▼ Abstract: Chemical cleansing with immersion in denture cleansers has been indicated for denture biofilm control in patients with limited motor capacity. Although previous studies have shown that a single immersion in those agents is able to substantially reduce Candida albicans biofilm levels, the effect of the routine use of denture cleansers on the Candida residual biofilm is poorly understood. This study evaluated the efficacy of daily use of an enzymatic denture cleanser on C. albicans biofilm formed on denture base materials; and the enzymatic activities of Candida biofilm cells after daily exposure to this cleanser agent. Polymethyl methacrylate (PMMA) and polyamide resins specimens were prepared (n=54), and their surface roughness was standardized (0.34 ±0.02 ?m). Saliva-coated specimens were randomly divided by lottery into 12 groups (n=9) for biofilm assay. C. albicans biofilm was formed for 72 hours, and then specimens were treated for 1, 4 or 7 days, once a day, with an enzymatic cleanser (Polident 3 Minutes), or distilled water (negative control). Remaining adherent microorganisms were removed from the treated specimens by ultrasonic waves at 7 watts for 30 seconds, and then colony-forming units (CFU) were calculated and remaining cells enzymatic activities were determined. Data were analyzed by 1-way or 2-way ANOVA followed by the Tukey-Kramer test. C. albicans biofilm formed on polyamide resin showed significantly higher Candida levels and phospholipase activity (p<0.001) than biofilm formed on PMMA resin. The enzymatic cleanser significantly reduced C. albicans levels in all evaluated periods (p<0.001); however, the number of this microorganism increased with time, showing statistical difference among the treatment periods (p<0.001). The daily exposure to the denture cleanser increased Candida cells virulence, with regard to phospholipase activity. Our study has shown that the enzymatic cleanser daily use did not prevent C. albicans proliferation in residual biofilm; however, this agent reduced this fungus rate of growth.

▼ Abstract: Candida spp. biofilm formed on removable denture surfaces is considered the main etiologic factor of candidosis, being the C. albicans and C.glabrata the species most frequently found in this condition. The antifungic fluconazol (FLZ) is commonly used in the treatment of candidosis, however its success is limited due to the resistance developed by Candida to this medicament. Considering the importance of the structure and morphology of Candida biofilms in the candidosis, the aim of this study was to evaluate the effect of FLZ on the bioactivity, biostructure and morphology of Candida spp. biofilms formed in the presence of this antifungal agent. Specimens (10 mm x 2 mm) were fabricated using water bath poly(methylmethacrylate) resin (PMMA). Salivary pellicles were formed on the PMMA surface, and biofilms of a reference strain and two clinical isolates of C. albicans (ATCC 90028, P01, P34) and C. glabrata (ATCC 2001, P11, P31) were developed for a period of 48h. Two groups were formed: control and experimental. FLZ at 2.56 µg/mL, concentration bioavailable in saliva, was added to the medium of the experimental group. The culture mediums of the control and experimental groups were changed at 24 hours. The bioactivities of the biofilms were evaluated with XTT reduction colorimetric assay. The biostructure was analyzed by the Confocal Scanning Laser Microscopy and the cell morphology analyzed by the Transmission Electron Microscopy. The data were analyzed by Student's t-test, with significance level set at 5%. The presence of FLZ decreased the bioactivity of all C. albicans biofilms (p<0.001), it did not change the structure and morphology of P34. As regards C. glabrata biofilms bioactivity and biostructure, no statistically significant differences were found between control and experimental groups for biofilms of all strains. It could be concluded that the alterations in bioactivity, biostructure and cell morphology in response to the treatment with fluconazole, bioavailable concentration present in saliva, depends on the Candida spp. strain Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: Candida infections have high prevalence; therefore, better understanding of the development mechanisms of biofilms is required for the reduction of virulence and for more appropriated clinical management. The aim of this study was to analyse the virulence of Candida albicans biofilms developed under different conditions. The role of biomaterial surfaces, salivary pellicle, and stage of biofilm development has been reported in Chapter 1. The influence of the presence of other microorganisms in virulence of C. albicans and on the interaction with the epithelium was evaluated in Chapter 2. The role of the atmosphere and of the biofilm¿s bacterial population was investigated in Chapter 3. In Chapter 1, C. albicans biofilms were developed on acrylic resin and titanium discs coated with saliva pellicle, or saliva with blood plasma pellicle. The materials¿ surfaces were analysed with regards to surface roughness and surface free energy (SFE). We evaluated the number of viable organisms, the DNA concentration, the metabolic activity, the expression of virulence factors and the architecture of the biofilms. There were no differences in the surface roughness of materials. The pellicles eliminated the differences between SFE of materials. Higher SFE was observed for discs coated with pellicles of saliva with plasma. The number of viable organisms, the DNA concentration and the metabolic activity increased throughout the biofilm maturation. Higher metabolic activity, increased expression of ALS1, ALS3 and HWP1, and more hyphae were observed in biofilms grown in the presence of saliva with plasma pellicle. There were no differences between the materials. In conclusion, the presence of saliva with plasma pellicle increases the C. albicans virulence. In chapter 2, mature biofilms (72 h) of C. albicans, or C. albicans with bacteria, were developed on the surface of acrylic resin discs. These biofilms were then analysed or used to infect a reconstituted human oral epithelium model (RHOE). Biofilms were evaluated according to the number of hyphae and the expression of virulence factors. The epithelial response was evaluated by the expression of IL-18 and Dectin1, by the activity of lactate dehydrogenase enzyme (LDH), and with regards the epithelial invasion. Increased number of hyphae and increased expression of HWP1, SAP4 and SAP6 were observed in multi-species biofilms developed on acrylic. Multi-species biofilms that have infected RHOE also had a greater number of hyphae and increased expression of ALS3, EPA1, SAP6 and HWP1. Consequently, these epithelia showed greater tissue invasion, higher LDH activity and higher IL-18 expression. We concluded, therefore, that the presence of bacteria promotes the virulence and pathogenicity of C. albicans. In Chapter 3, biofilms of C. albicans and C. albicans with streptococci were developed on titanium, aerobically and anaerobically. C. albicans biofilms (mixed or not-mixed with streptococci) were also grown in the presence Porphyromonas gingivalis, anaerobically. Biofilms were… Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Silva, Wander José da, 1980- (advisor), Del Bel Cury, Altair Antoninha, 1948- (coadvisor), Universidade Estadual de Campinas.

▼ Abstract: The opportunistic pathogen Candida albicans and streptococci of the Mitis group form complex communities in multiple oral sites, where the environment and nutrient availability change constantly. We aimed to study structural and virulence characteristics of Candida albicans biofilms in the presence or absence of S. oralis, growing on a three-dimensional model of human oral mucosa, under different conditions: (1) moisture of mucosal surface (wet or semi dry), (2) nutrient availability (BHI supplementation on culture media) and (3) hyphal morphotype (hyphae or pseudohyphae). For this it was used a three-dimensional model of the human oral mucosa formed by immortalized oral keratinocytes (OKF6-TERT2 or SCC15 cell lines) on a fibroblast-embedded collagenous matrix to grow biofilms. Infections were carried out using Streptococcus oralis 34, a C. albicans reference strain and pseudohyphal mutants with a homozygous deletion of the ndt80, or tup1 gene. Determination of biofilm biovolume and structure was done by confocal scanning laser microscopy with biofilms stained by immunofluorescence using an anti-Candida antibody and a Streptococcus probe. As determinant of virulence, 5-?m-thick tissue sections were stained same way or with hematoxylin and eosin in order to detect invasion of microorganisms. Also tissue damage was measured by lactate dehydrogenase release in the culture media. Statistical analyses were performed using SigmaPlot 12 software at 5% significance level. Data were evaluated by analysis of variance (ANOVA) and when statistical significances were found, all pairwise multiple comparison procedures were performed with Bonferroni t-test, with ? = 5%. Under wet conditions C. albicans extended long intertwined hyphae, forming a homogeneous surface biofilm. Mixed biofilms had a stratified structure, with S. oralis growing in close contact to the mucosa and C. albicans growing on the bacterial surface. Under semi-dry conditions, C. albicans formed localized foci of dense growth from which hyphae extended radially to intertwine with hyphae from adjacent foci. In mixed biofilms this promoted focal growth of S. oralis co-localizing with C. albicans. Although Candida biofilm biovolume was significantly greater under wet conditions (P<0.001), there was minimal tissue invasion compared to semidry conditions where the epithelial barrier was completely destroyed. Supplementing the infection medium with nutrients under semidry conditions did not change the biofilm architecture but intensified focal growth and increased biofilm biovolume and tissue invasion/damage (P<0.001), proportionally to the tested concentrations. Pseudohyphal mutants formed defective mixed biofilms, with most S. oralis in contact with the epithelial surface, below the pseudohyphal mass. Interestingly, the presence of S. oralis promoted fungal invasion and tissue damage under all conditions. Moisture, nutrient availability, hyphal morphotype and presence of S. oralis strongly affect architecture and virulence of mucosal fungal biofilms Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: Considering the impact of biomechanical environment and bone condition on the prognostic of therapy with dental implants, this study aimed (1) to evaluate the influence of the type of prosthetic abutment associated to different implant connections on bone biomechanical behavior of immediately or delayed loaded implants (Chapter 1); (2) to investigate the effect of single or combined application of high-frequency loading through whole body vibration (WBV) and bisphosphonates (Alendronate, ALN) on the mechanical competence and micro-structure of osteoporotic bone (Chapter 2); (3) to evaluate the impact of combination therapy with WBV and ALN at differing dosages on osteoporotic bone micro-architecture (Chapter 3). In Chapter 1, tridimensional (3D) finite element models comprising a mandible with a single molar implant were created varying the type of prosthetic abutment (UCLA or conical), implant connection (external hexagon, EH or internal hexagon, IH), occlusal loading (axial or oblique), both for immediately or delayed loaded implants. Analysis of variance was used to evaluate the peak of maximum principal stress and strain in cortical and trabecular after applying a 100 N occlusal load. It was observed that the type of prosthetic abutment and implant connection influenced the bone stresses and strains of immediately loaded implants, showing the association of conical abutments with IH implants the lower values of bone stress/strain. In Chapter 2, 34 female Wistar rats were ovariectomized (OVX) or sham-operated (shOVX) and divided into five groups: shOVX, OVX-shamWBV (shWBV, lack of mechanical stimulation), OVX-WBV, ALN-shWBV and ALN-WBV. WBV loading was applied for 10 min/day using 10 consecutive steps of HF loading (130, 135, 140, 145, 150, 130, 135, 140, 145, 150 Hz) at acceleration of 0.3g for 14 days. At the same experimental period, ALN was administered at a dosage of 2 mg/kg/dose, 3x/week. Finite element analysis based on micro-CT was employed to assess bone biomechanical properties (stiffness and strength), relative to trabecular and cortical bone micro-structural parameters. Compared to HF loading, ALN treatment is preferred for improving the compromised mechanical competence of osteoporotic bone. In addition, the association of ALN with HF loading results in an additive effect on bone micro-architecture. In Chapter 3, 56 female Wistar rats OVX or shOVX were divided into seven groups: shOVX, OVX-shWBV, OVX-WBV, ALN(x)-shWBV, ALN(x)-WBV, ALN(y)-shWBV and ALN(y)-WBV. The application of WBV was performed according to the same protocol described previously. Nevertheless, ALN therapy, alone or in combination with WBV, was administered at different dosages [ALN(x): 2mg/kg, conventional dose or ALN(y): 1 mg/kg, reduced dose], 3x/semana. Both mechanical and pharmacological treatments were performed for 6-week experimental period. Micro-CT analyses were performed to evaluate the trabecular bone micro-architecture at the end of experimental period. It was observed that a ALN therapy at a lower concentration… Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: : The oral rehabilitation with implant-supported fixed prosthesis in the maxilla is the most suitable option and is widely enshrined in the literature. Due to the high requirement aesthetics in this area, the rehabilitation with implants, single or multiple, is a big challenge for both the professional and the patient. In this sense, not only the aesthetics but also the mechanical factors acting in these rehabilitations are very important to the longevity of treatment. Thus, the positioning and the number of the implants to be installed in the anterior maxilla have been decisive factors in the planning of the case, both from the aesthetic and mechanical point of view. In this study was evaluated the influence of the number and the arrangement of the implants in stress distribution in the implants, components and prosthetic rehabilitation in different arrangements (04 implants (4I), 02 implants in the region of the central incisors (CS), 02 implants being one the central incisor and the opposite lateral incisor (CSLS) implants 02 in the region of the lateral incisors (LS)) in the anterior maxillary area by means of the method three-dimensional (3D) finite element method (FEM). The 3D models were obtained and they contained the following structures: anterior maxillary region (cortical and trabecular bone), cylindrical titanium implants (3.75x11mm) prosthetic interface type Morse taper, abutments in titanium alloy, zirconium framework and ceramic crowns. Bone tissue and the crowns were obtained by tomographic cone Beam image. The implants, abutments and prosthetic framework were created from the CAD computer software (Computer Aided Design) SolidWorks®. Subsequently the models have been exported to the computer software of numerical analysis ANSYS Workbench® for analysis and achievement of results. The magnitude of the force applied on each unit was 37,5N distributed on the palatine faces of the prosthetic crown, at a 45° angle to the long axis of each crowns, i.e. the total load applied to the prosthesis was 150N. The data obtained emphasized the stress distribution and the higher stress values the equivalent von Mises (MPa) of each model. The number of implants revealed a significant influence on the mechanical behavior of rehabilitation and other structures, justified by the lower stress values found in the model 4I, in all its components (112 MPa/Implants, 93 MPa/Abutments, 61MPa/Framework and 53 MPa/Ceramic crowns). However, when the number has decreased to two implants, as seen in the LS model, there was a higher concentration of tension in all the evaluated structures (654MPa/Implants, 716 MPa/Abutments, 200 MPa/Framework and 182 MPa/Ceramic crowns). The CS and the CSLS models showed similar mechanical behavior to each other, but with lower stress values that the LS model and larger than the 4I model (295 and 412 MPa/Implants, 174 and 228 MPa/Abutments, 195 and 80 MPa/Framework and 121.17 and 107 MPa/Ceramic crowns respectively). It was concluded that a larger number of implants to support a FPPs,… Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: The evaluation of microbial interactions is extremely important for the comprehension of communities¿ development and their control. As biofilm form, bacteria are adhered to salivary-pellicle covered-surfaces and still interacting with other species for coadhesion and coaggregation. These interactions occur due to adhesins molecules present onto microorganisms surfaces. Two important adhesins are the Receptor of Polysaccharide (RPS) in S. oralis (So) and fimbriae onto Actinomyces oris (Ao) surface, both bacteria are first colonizers of oral surfaces. These adhesins have essential role in bacterial adhesion onto the pellicle, in the interaction with other microorganisms and on biofilm formation. Their relationship and the molecular base of interactions with the fungus C. albicans are still under investigation. The aims of this study were to evaluate the interactions between S. oralis (So), A. oris (Ao) with C. albicans (Ca) and the role of RPS and Fimbriae I/II planktonically and as biofilms. Combinations of dual and triadic species in wild types and mutants strains lacking RPS and Fimbriae types I and II were designed for that: I (Ao + Ca), II (So + Ca), III (So + Ao + Ca), IV (Ao ?Fim + Ca), V (So ?RPS + Ca), VI (Ao ?Fim + So + Ca) and VII (Ao ?Fim + So ?RPS + Ca). The mono-species biofilms were developed as well. The microorganisms grown planktonically for 3 hours in YPTG medium (YNB, peptone, triptone in phosphate buffer supplemented with glucose) and the interactions evaluated by fluorescence microscopy. The biofilms were developed onto resin discs and glass cover slips covered with salivary pellicle (2 hours) in the same medium until 24 hours. The viability was determined by biomass in 7 hours biofilms and Colony-forming units (CFU/mL) in 1.5 and 24 hours biofilms. The temporal development and microbial distribution were evaluated by confocal, optical and fluorescence microscopies. So and Ao interacted as wild types and particular biofilm formation was observed in the presence of one or two mutant strains. All bacteria interacted planktonically with Ca in all combinations and do not compete for binding sites onto fungal surface. The presence of Ca in biofilms influenced the bacterial community improvement, Ao mutant strain to biofilm formation and bacteria stimulated hyphal growth. There is a new distribution and cell prevalence in three-species biofilms containing mutant bacteria. Based on these results, it can be concluded that first colonizers bacteria So and Ao interact with Ca planktonically or within biofilms, although the interspecies interactions are RPS and fimbriae independent Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: Dental implant surface treatments are being developed in order to increase roughness and consequently improve chemotaxis to optimize osseointegration. Despite the clinical success of dental implants, it is known that in many cases, marginal bone loss occurs in the peri-implant area and the mechanism related to this process is not clear in the literature. Some studies described that during implant insertion the peaks created to produce rougher surfaces, are prone to break and micro and nanoparticles of titanium are released in the peri-implant tissue culminating in an osteolytic process. The immune system reacts against the shed particles and the macrophages are the first cell linage interacting with titanium particles stimulating an inflammatory process that can overproduce cytokines, leading to bone resorption. In order to evaluate inflammatory response by macrophages, an in vitro study (Study 1) was developed culturing THP-1 cell linage in the presence of micro and nanoparticles of titanium in association with Lipopolysaccharide from Porphyromonas gengivalis (LPS PG) for 12h, 24 and 48h and pro-inflammatory cytokines related to the osteolytic process TNF-?, IL1-?, IL-6 were evaluated. Gene expression was analyzed using ??Cq method and Elisa comparing to the standard curve, the data were analyzed using ANOVA two-way and Tukey¿s test (p<0.05). As results it was observed that in the presence of micro and nanoparticles of titanium gene expression and protein production were increased compared to control, and the association of titanium particles and LPS PG did not increase gene expression and protein production compared to groups treated with titanium particles. Also to assess bone reaction in the presence of titanium microparticles an animal study (Study 2) was performed with 14 New Zealand White Rabbits, implants with turned surface were placed in tibia with 3mg of microparticles of titanium and femur using 1mg of microparticles of titanium in both legs of the animals. Data were analyzed using regression mixed model (p<0.05). After 7 and 28 days bone contact decreases in test group compared to control by histological and histomorphometric analysis. Moreover, 6 animals received 12 implants in tibia to evaluate the main osteogenic genes and after 7 days a decrease in the expression was observed. Conclusively the presence of titanium particles affects early stages of osseointegration Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: This study assessed the influence of four implant macrogeometries on bone properties and peri-implant health parameters during the healing process. Ninety-nine implants were placed bilaterally in posterior mandibles of 23 patients. Each patient received at least 4 unique dental implant macrogeometries: the standard geometry Integra (IN) and three geometries that induce a `healing chamber¿: Duo (D), Compact (C) and Infra (IF). The insertion torque (IT) and the implant stability quotient (ISQ) were measured as a proxy for the primary or secondary stability (PS and SS, respectively). In addition, three clinical parameters related to the peri-implant health were monitored: the visible plaque index (VPI), the peri-implant inflammation (PI) and the presence of calculus (CC). The data were collected after 7, 14, 21, 42, 60 and 90 days. The outcome variables were compared using one-way ANOVAs and repeated measures ANOVAs or ANOVA-R followed by the Turkey-Kramer test. The Spearman correlation test was performed to investigate the associations between: i) bone and mechanical characteristics (IT x PS), ii) bone type and type of implant, iii) IT and ISQ for all time intervals. All analyses were considered significant at the 5% level. Macrogeometry did not significantly influence IT and ISQ values. The minimum ISQ was recorded after 7 days (p = 0.0001). An intermediate ISQ was found after 14 days, where the ISQ reached values that are statistically identical to the primary stability. The VPI was influenced by the healing time (p = 0.0001) and by the interaction between time and implant macrogeometry (p = 0.0328), with significantly higher scores for the D and IN implants after 7 days. The PI was only influenced by the healing time (p = 0.0001), and showed a significant decrease from the time of 7 (1.07 ± 0.89) to 21 days (0.18 ± 0.18). A significant positive correlation was observed between IT and total bone height (r = 0.2504; p = 0.0149) and between IT and lingual cortical width (r = 0.2621; p = 0.0107). Conversely, IT and medullary thickness (r = -0.2193, p = 0.0337), total bone width (r = -0.2865; p = 0.0054) and buccal cortical width (r = -0.22227, p = 0.0319) were negatively correlated. The most significant correlation between IT and SS values was recorded by D implants after 90 days ?? (r = 0.5964; p = 0.0027). Within the limitations of this study, it can be concluded that macrogeometry did not influence IT nor ISQ values. Minimum stability was observed after 7 days, and the secondary stability started between 7 and 14 days. The relationship between IT and SS was more evident for the Duo implant, but only in the final stage of healing process (90 days) Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: The use of mini-implants (IDR) and mini-implants (IM) has been widespread, however, studies are still needed to assess their predictability, clinical, biological and functional behavior as mandibular overdenture (OM) retainers. In order to verify the clinical and functional success of this treatment in total edentulous patients with limited bone availability, four different studies were delineated: I) Systematic review (SR) and meta-analysis, a systematized search in 6 databases to identify studies using MI and NDI as MO retainers and reporting data on survival, success and marginal bone loss (MBL) for meta-analysis; II) Longitudinal clinical study that evaluated the clinical behavior of 60 NDI as MO retainers installed in 30 patients with clinically atrophic mandible and high edentulism time, were followed for up to 1 year after loading. The outcomes were: peri-implant health (plate index - PI; calculus - C; gingival index - GI; probing depth ¿ PD; bleeding on probing - BoP), Primary and secondary stability of the implants (ISQ), survival, success, MBL, marginal bone level change (MBC), and description of complications/maintenance during the treatment; III) Longitudinal clinical study with 1 year of follow-up, that evaluated the masticatory function (MF) evolution and oral health related quality of life (OHRQoL) of 23 edentulous patients with clinically atrophic mandible and high edentulism time were rehabilitated with mandibular overdenture. The MF was evaluated through masticatory performance (MP) tests and swallowing threshold (ST). And the OHRQoL was evaluated through three different questionnaires OHIP-ENDENT, GOHAI and DIDL. IV) Longitudinal clinical study comparing the MF, OHRQoL and satisfaction of 26 edentulous patients classified as atrophic patients (AP) and non-atrophic patients (NAP) before and up to 1 year after MO loading. The outcomes were MP and ST tests and DIDL questionnaire as an OHRQoL indicator and patient satisfaction. Through the results of study I, it is demonstrate that MI and NDI present clinical behavior similar to those of standard diameter implants (SDI), MBL found for MI and NDI were clinically similar to those reported in the literature for SDI. NDIs show better predictability than MI when conventionally loaded. In the clinical study II, we observed that the NDI present clinical behavior similar to that already reported for SDI, directly dependent of the patient care and peri-implant tissues monitoring. The PD decreased gradually, evidencing the soft tissues sealing around the attachments protecting the marginal bone. The MBL 1 year after MO loading (-0.23 ± 0.5 mm) was similar (P> 0.05) at the MBL immediately the implant installation (-0.13 ± 0, 47 mm). The MBC after 1-year loading was -0.06 ± 0.64 mm. On average, a return per patient was required to adjust the base or exchange the pink O-ring. The clinical study, referring to article III described a significant improvement in MF and OHRQoL of the clinically atrophic edentulous patients after the MO loading, and the… Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: Due to the increasing demand for aesthetic procedures, the use of high-strength ceramics is coming every day more common in implantology. The use of ceramic abutments has presented poor mechanical behavior and unfavorable interaction with the implant connections. As an alternative, ceramic restorations with custom staining and emergency profile can be made using CAD/CAM systems and chairside cemented on titanium bases out of the mouth, allowing control over cement excess flow and margins finishing. Many commercially available digital systems using CAD/CAM technology could be used to produce restorations over titanium bases, optimizing the fabrication process and maybe showing better marginal and internal adaptation when compared to conventional systems. Different manufacturers offer digital library of their products where pre-defined internal gaps are available. There is no consensus regarding which internal gap offer better mechanical behavior as well as what is this influence on internal and marginal ceramic prosthesis adaptation. In the present study, thirty - six coppings (n = 36) of Ceramill ZOLID FX zirconia (Amann Girrbach) with three different internal gaps (25 µm, 50 µm e 75 µm) were cemented with Panavia F (Kuraray) on titanium bases (Link - Neodent), 12 on each group. Then, measurements of the marginal and internal interfaces were obtained by optical microscopy, and subjected to pull out in a universal machine with 0.5 mm / min head velocity, then analyzed comparatively. Results were compared statistically by Tukey test with significance level of 5% and Pearson's correlation. There was no correlation between the different internal gaps and Pull out resistance (p> 0.05) and no significant influence of the different internal gaps in the marginal adaptation (p> 0.05). Only a statistically significant difference (p <0.05) was observed in measures of internal gaps in the cervical region. All groups tested showed vertical marginal discrepancy within the clinically acceptable limits (120 µm). There was no influence of tested internal gap levels on pull out resistance Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: The development of Candida albicans biofilms may be mediated by a differential expression of proteic ligand sites in the acquired pellicle formed onto the oral prosthesis surfaces. Therefore, the main objective of this study was to evaluate the influence of salivary and plasmatic-derived proteins on the development of C. albicans biofilms. In the first chapter the state-of-the-art was reviewed for methodologies applied to the analysis of proteins. From the knowledge of the methodologies, the research was realized aiming to characterize the protein profile of acquired pellicles (ADP) on poly(methylmetacrilate) surfaces' specimens in the presence of saliva or saliva supplemented with blood plasma. ADP composition was analyzed by mass spectrometry techniques, which results demonstrated a significant difference in the obtained proteome between the groups. Moreover, the influence of these pellicles was evaluated for the surface free energy (SFE) and expression of virulence factors by C. albicans biofilms. The findings demonstrated that the binding of plasmatic proteins in the ADP determined increases in both experimental variables. From these data, the individual effect of some identified ADP proteins was evaluated on C. albicans biofilm development. With this objective, C. albicans biofilms were developed (90 min, 24, 48 and 72 h) over mono-protein pellicles of albumin; mucin I and II; lactoferrin; fibrinogen; C3b; IgA and histatin 5. For each time point, biofilms were analyzed for metabolic activity (XTT assay), structural biofilm conformation (Confocal scanning laser microscopy) and, expression of virulence factors by means of enzymatic activity assays. Based on the generated evidences of these studies, we can conclude that adsorbed salivary and plasmatic proteins as proteic integuments keep their biological function, and thus exert a modulatory influence on C. albicans biofilm development Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: Strategies to prevent and to reduce biofilm formation on dentures are necessary, since they may become a reservoir of microorganisms. Additionally, it is important, in establishing a protocol for denture cleaning, to evaluate the effect of the cleaning agent on the prosthetic material and the patients' acceptability. Therefore, the objective of this study was to evaluate the effect of sodium hypochlorite (NaOCl) 0.5% on biofilm, color stability and surface roughness (Ra) of removable dentures besides the patients' satisfaction with the treatment. Fifteen volunteers were recruited and, after accepting the conditions of the Term of Consent approved by the Ethics Committee of FOP / UNICAMP, were instructed to daily immerse their dentures in a 0.5% NaOCl solution for 3 minutes. The follow-up time was 90 days and outcome variables were measured on baseline and on days 30, 60 and 90. For microbiological evaluation, samples were obtained from dentures and saliva. Swabs were taken from the whole surface of the dentures and, then, individually placed in a sterile tube containing 3 ml of PBS. Next, each volunteer was asked to spit into an empty sterile tube. All tubes were sonicated (7W, 30 s), the initial solutions serially diluted and plated in triplicate on blood agar and CHROMagar and, after an incubation period of 48 h at 37°C, the number of colony forming units (cfu/mL) was determined. Color stability was measured with a reflectance spectrophotometer and evaluated using the CIELab system. It was also quantified in accordance with units of the National Bureau of Standards (NBS). To Ra assessment, an in situ design was developed. Specimens (5 x 5 x 2 mm) (n = 90) of heat-polymerized acrylic resin were fabricated and fixed in the buccal posterior surface of lower dentures. The surface roughness was measured using a profilometer. To evaluate the acceptability of the cleaning protocol, each volunteer was asked to translate in values their degree of satisfaction with the treatment at an interval ranging from 0 (totally dissatisfied) to 10 (totally satisfied). A significant reduction in the number of total micro-organisms (ANOVA; p ? 0.05) and Candida spp was observed throughout the treatment. Although changes had been observed in L *, a * b * values, there were no significant color changes (Friedman; p ? 0.05). The surface roughness did not present significant changes after the evaluation period (Kruskal Wallis; p ? 0.05). The volunteers' satisfaction increased throughout the experimental period, reaching 87% of individuals totally satisfied. Data revealed that the 0.5% NaOCl immersion protocol was effective in reducing microorganisms, color changes exhibited for all dentures can be considered clinically acceptable and the surface roughness did not show significant changes. Also, the cleaning method was well accepted by volunteers Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: The maintenance of adequate denture hygiene is of paramount importance to prevent biofilm accumulation which acts as a reservoir of microorganisms that can cause local and systemic infections. Although brushing is a well established method for denture cleaning, visual and manual limitations of some patients can reduce its efficacy. Therefore, the use of denture cleansers (DC) has been indicated as a complementary method for denture hygiene. Considering this, the aims of this study were to (i) evaluate, in an in vitro model, the effect of daily immersion in DC on a multispecies biofilm develop on denture-base acrylic resin and (ii) assess the effect of DC on controlling biofilm from removable partial dentures (RPD) surfaces. For the in vitro study, specimens were fabricated using acrylic resin on which it was develop a multispecies biofilm (Candida albicans, Veillonella dispar, Streptococcus mutans, Streptococcus oralis, Fusubacterium nucleatum e Actinomyces naeslundii). After 64.5 hours of biofilm growth, the specimens were randomized into control and experimental groups. The specimens of experimental group were submitted to 3-minutes immersions on DC solution daily for seven consecutive days; the biofilms of control group were developed for the same period without any treatment. The biofilms from both groups were collected after 1, 4 and 7 experimental days (n=16) and analyzed for viable cells and polysaccharides concentration. Additionally, the biofilms topography and cellular morphology were analysed by scanning electron microscopy ) and confocal microscopy. For in vivo evaluation of DC, 25 volunteers that used RPD were selected. They were instructed to complement their dentures hygiene by immersing them on DC solution, for 3 minutes, during 15 days. The biofilm present on RPD was collected immediately before and after the experimental period and the number of total microorganisms, total streptococci and Candida spp. were quantified. In the in vitro study, it was observed that daily immersion on DC significantly reduced the total microorganisms in comparison to control group, in all periods evaluated. (Two-way Anova, p<0.05). This reduction was also observed for individual bacteria and F. nucleatum and V. dispar were not detected on biofilms exposed to DC. It was observed a gradual increase of C. albicans count in biofilms of experimental group while, in control group, Candida counts decreased and it was not observed viable cells after seven experimental days. Additionally, extracellular polysaccharides concentration was significantly higher in experimental group after 7 days of treatment (Two way Anova, p<0.05). The microscopy images revealed a remarkable presence of hyphae in experimental group. In clinical study, it was observed a reduction on total microorganisms and total streptococci. However, no difference was observed in Candida spp. counts (paired t-test, p<0.05). It can be concluded that daily exposure to DC reduced total microorganisms on multispecies biofilms but did no demonstrated efficacy… Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

The aims of this study were: to evaluate the influence of incorporation of fluorescent dye Rhodamine B (R) in the properties mechanical: cohesive strength (CS), elastic modulus (E) and flexural strength (FS) of the selfetching Clearfil SE Bond and etch-and-rinse Scotchbond Multi-Purpose (Study 1); validating the modified microtensile method using micro-specimens cross section of 0.09 mm2 (?TBS) and evaluate the influence of R in bond strength in dentin and interfacial integrity by confocal microscopy (study 2). To evaluate the influence of the dye, 0.16 mg/ml of R were incorporated into adhesives thus forming two groups for each adhesive: groups of labeled adhesives and no-labeled totaling 4 experimental groups. For the analysis of CS, E and FS the specimens were made from a silicone matrix. About the matrix were 10 ?L dispensed adhesive varying according to each group of adhesives stained or not. CS (n = 10), E and FS (n = 5) were evaluated in a universal testing machine at 0.5 mm/min until failure of the specimen. For visualization in confocal microscopy and bond strength analysis (n = 8), the adhesives were applied to the occlusal dentine surface 32 of human premolars. After procedures adhesives, composite crowns approximately (16 mm2) were built up with Charisma Opal (Kulzer - color A3). Then for testing modified microtensile, micro-specimens beam-shaped were prepared. Prior to mechanical testing micromorphological analysis of micro-sticks of the groups of labeled adhesives was performed using CLSM. Subsequently bond strength was measured using the modified microtensile test in a universal testing machine speed of 0.5 mm/min. The results showed that the behavior of the adhesive systems investigated did not change regardless of the presence of the dye, as there were no significant differences in mechanical properties studied: bond strength, tensile strength, flexural strength, modulus of elasticity, as well as interfacial integrity. The preparation of micro-specimens did not affect the results of the bond strength test. According to the analysis results and parameters: coefficient of variation percentage of fracture pattern and incidence of early failures, it is concluded that the modified microtensile test was considered a reliable method for evaluating the bond strength of adhesive systems. The confocal microscopic visualization technique yielded detailed information of the adhesive interface and can be well suited for evaluating the effectiveness of adhesive systems. Thus, it is possible to associate both methods give a more realistic and reliable adhesive restoration on the presence of fluorescent dye Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Paulillo, Luis Alexandre Maffei Sartini, 1962- (advisor), Universidade Estadual de Campinas.

▼ Abstract: Catecolamine-O-methyltransferase (COMT) is an enzyme with broad biological functions, including pain modulation, exerted through metabolization of substrates such as dopamine, epinephrine, and norepinephrine. It is well known that COMT activity is genetically polymorphic in humans, and correlates to individual pain perception and efficiency in its remission among temporomandibular disorder (TMD) patients treated with propranolol. Thus, our first aim was to investigate new single nucleotide polymorphism (SNP) that might mark for this benefit. Indeed, we have found a new SNP, rs165774 (G>A), that was associated with TMD or intermediate phenotypes in two different cohorts. This polymorphism, in turn, is in close proximity to a second SNP, rs165895 (T>C), both in the 3' untranslated region (3'UTR) of an alternative COMT mRNA that has not yet been characterized. Therefore, we also aimed to (i) verify the expression of this transcript in different human tissues and cell systems, tracking it through RT-PCR (Reverse Transcriptase - Polymerase Chain Reaction); (ii) predict the crystalline structure of the enzyme encoded by it, modeling it with discrete molecular dynamics; (iii) express it in a cell system and compare its relative expression and enzymatic activity to the conventional isoform, using RT-PCR and HPLC (High Performance Liquid Chromatography), respectively; and (iv) verify the effects of SNPs rs165774 and rs165895 on the transcript, creating different mutants by site-directed mutagenesis and observing their effects on the relative expression and enzymatic activity. Our findings show that (i) the alternative COMT transcript is expressed in different human tissues and cell systems; (ii) the crystalline structure of its enzyme exhibits a unique C-terminus that is distinct from the conventional isoform; and that this transcript is (iii) less relatively expressed and its enzyme is less active than the conventional transcript and enzyme, respectively, and (iv) is regulated, at transcriptional level, by the SNPs rs165774 e rs165895. With this study, we conclude that SNP SNPs rs165774 is a strong genetic marker for TMD; that along with SNPs rs165895, they are located in the 3'UTR of an alternative COMT mRNA which proved, for the first time, to be able of encoding an alternative isoform of the enzyme that exhibits enzymatic activity; and that this alternative COMT mRNA is regulated, at transcriptional level, by both SNPs Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Rizzatti-Barbosa, Celia Marisa, 1957- (advisor), Universidade Estadual de Campinas.

▼ Abstract: The colonization of different substrata present in the oral cavity by microorganisms and the biofilm development are the etiological factors of the majority of oral diseases. Besides the teeth, materials such as titanium and polymethylmetacrylate are commonly found in this environment and the role these substrata play on the prevalence of bacterial and fungal population in oral biofilms are poorly understood. In addition, the behavior of microbial population of multispecies oral biofilms in the presence of antimicrobials released in saliva remains unknown. Thus, the aim of this study was (i) to evaluate the effect of different substrata on the prevalence of microorganisms in an oral multispecies biofilms and (ii) the effect of antimicrobials released in saliva on the microbial population of a multispecies biofilms. For the first study hydroxyapatite, titanium and polymethylmetacrylate (PMMA) discs were used as substrata for biofilm development mimicking tooth enamel, dental implant and denture base, respectively. The multispecies biofilm model was composed by five bacteria (Streptococcus oralis, Streptococcus mutans, Actinomyces naeslundii, Veillonella dispar and Fusobacterium nucleatum) and one yeast (Candida albicans). Mature biofilms (64.5 h of development) were removed by ultrasonic waves, plated on agar media and CFU counts of each microorganism were calculated. Scanning electron microscopy was used to visualize the materials' surface. Data were analyzed by one-way ANOVA. For the second study the same multispecies biofilm model was used. Two antibiotics, azithromycin and metronidazole, and one antifungal, fluconazole, were evaluated. Mature biofilms (64.5 h development) were exposed to azithromycin, metronidazole or fluconazole at concentrations found in saliva of 2.12 ug/mL, 15.15 ug/mL and 2.56 ug/ml, respectively, for 24h. After this period, the biofilm was removed by ultrasonic waves, plated on agar media and CFU counts of each microorganism were calculated. Scanning electron microscopy and confocal scanning laser microscopy with cells stained by fluorescent in situ hybridization (FISH) technique were used to assess the biofilm structure. Data were analyzed by independent-samples t-test and Mann-Whitney nonparametric test. The first study showed no difference in the biofilm population for each microorganism among the three materials evaluated (p>0.05). In the second study, all antimicrobials evaluated were able to change microbial population (p<0.05), however none of the antimicrobials was able to completely eliminate a specific microorganism from the biofilm. Azithromycin reduced A. naeslundii and V. dispar population while increased C. albicans (p<0.05). Metronidazole reduced all the microorganisms evaluated, with a great reduction for V. dispar and F. nucleatum (p<0.001). Fluconazole reduced C. albicans and F. nucleatum population and increased S. oralis and V. dispar counts (p<0.05). It can be concluded that the substrata were not able to interfere with the formation of multispecies biofilms… Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: Dental implants receive surface treatments to create micro- and nanostructures on surface to increase the contacting area with bone, which favors osseointegration. However, the resistance of these structures in face of the friction against the bone tissue during the implant insertion is not evaluated yet. Thus, the objective in this study was to quantify by means of roughness parameters the surface wear caused by the insertion procedure in the bone tissue and to investigate the presence of loose titanium particles at bone-implant interface (Chapter 1); to evaluate the influence of plasma nitriding treatment on surface properties of titanium and on its biocompatibility (Chapter 2); and to investigate the protein adsorption in vitro and osteogenesis around amino-functionalized implants placed in rabbits (Chapter 3). In Chapter 1, roughness of three implants representing different geometries and surface treatments were evaluated by interferometry before and after insertion into bovine rib blocks. The blocks were also evaluated by microscopy to identify titanium particles at the interface. The amplitude of all roughness parameters were smaller after the insertion procedure for all implant groups and microscopic images revealed presence of loose titanium and aluminum particles at the interface, concentrated at the cortical crest. Therefore, it was concluded that moderately rough surfaces can release loose particles at the interface. In Chapter 2, titanium discs (12.7 × 2 mm) with moderately rough surface were nitrided by cold plasma. Human osteoblasts (SAOS-2) were cultivated on the discs for 1, 3, 5 and 7 days. Cell proliferation and differentiation were evaluated by MTS, production of alkaline phosphatase and by qPCR. It was observed that plasma nitriding increased the nitrogen content on surface, and also hardness, wettability and nanostructures. No significant difference between titanium and nitrided surface was seen on cell behavior. Therefore, it was concluded that nitriding treatment increase surface hardness and does not jeopardize the biocompatibility of titanium. In Chapter 3, titanium was amino-functionalized by 3-aminopropyltriethoxysilane. Protein profile was identified by mass spectroscopy after discs were immersed in human blood plasma for 3 h. To evaluate osteogenesis, titanium implants (3.75 × 6 mm) were placed in 10 New Zealand adult rabbits (1 in the femoral distal metaphysis and 2 in the tibial proximal metaphysis of both legs). The animals were sacrificed after 3 and 6 weeks and implants with adjacent bone were collected, fixed and included in resin blocks. After, 20 ?m thick slides were prepared at the central region of each implant and stained by toluidine blue. Histomorphometric analysis consisted of measuring the bone-to-implant contact (BIC). Treated surface exhibited higher amount of adsorbed proteins; however, lower relative abundance of fibronectin. No significant difference was identified between the groups for BIC values after 3 and 6 weeks. Therefore, amino-functionalization… Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: The short implants are an alternative treatment for edges reabsorbed. However, using short implant at the posterior atrophic mandibular has showed higher biomechanical risk due to higher crown following to the increase of inter-maxillary space. Aiming to offset the unfavorable biomechanics is advisable to use less rigid restorative materials, retention system for the prosthesis to facilitate the stress distribution and use of implants with larger diameters. However, the influences of these prosthetic factors and insertion torque on stress concentration are not clearly understood. Thus, the objectives were to evaluate by tridimensional finite element method the influence of: I) crown-to-implant (C/I) ratio, retention system, restorative material and occlusal loading on stress concentrations within a single posterior crown supported by a short implant; II) different insertion torques on the stress and strain distribution in cortical and cancellous bones. For the first objective, thirty-two finite element models of an atrophic posterior edentulous mandible were created. Each model received a metal-ceramic crown, cemented or screwed, over a single external hexagon implant with 7 mm length and 5 mm diameter at the first molar region. The C/I ratio ranged from 1:1, 1.5:1, 2:1 to 2.5:1. The models were loaded by simulating a normal and traumatic occlusion. After the convergence analysis of 5% to mesh refinement, the numerical analysis was performed on Ansys Workbench 10.0® software. The maximum principal stress for cortical and cancellous bone and von Mises stress (?vM) for the implant and abutment screw were computed and analyzed using analysis of variance. For the second objective, six models were built and each of them received an implant with one of the following insertion torques: 30, 40, 50, 60, 70 or 80 Ncm. The ?max and the maximum principal strain (max) were obtained for cortical and cancellous bone. Pearson's correlation test was used to determine the correlation between insertion torque and stress concentration in the periimplant bone tissue. The results showed that traumatic occlusion and increasing C/I ratio significantly increased the stress concentration in cortical bone, cancellous bone, implant and prosthetic screw. The prosthetic retention system significantly influenced the stress concentration, but at a lower level than the C/I ratio or occlusal loading. The screw-retained prosthesis displayed higher stress levels than the cement-retained prosthesis in all components. The stress concentration was not affected by the restorative material. For the second objective, the increase in the insertion torque generated an increase in the ?max and ?max values for cortical and cancellous bone. It is concluded that occlusion is main factor that most influences the stress concentration at the implant prosthodontic supported by short and high insertion torques that increase concentrations of stress and strain in the peri-implant bone tissue Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: The restoration of severely broken-down and endodontically-treated incisors (ETI) is a major challenge in daily practice and is commonly undertaken using various types of posts and composite resin buildups. Additional time, materials and risk involved in the placement of the post is not accompanied by an increase in mechanical resistance of the root-restoration complex. Use of a post was even correlated to a higher rate of unrestorable fractures. The aim of this study was to investigate the restoration of broken-down endodontically-treated incisors with and without ferrule using glass ceramic crowns bonded to composite resin core-buildups with or without post. Article number one used forty-five decoronated endodontically-treated bovine incisors divided in 3 groups: FP as control (2-mm ferrule, a glass-fiber post and nanohybrid composite resin buildup), FNp (with 2-mm ferrule and nanohybrid composite resin build-up) and NfP (without ferrule, glass fiber post and nanohybrid composite resin build-up). The second study used sixty decoronated endodontically-treated bovine incisors without ferrule divided in 4 groups: NfPfB (glass-fiber post and bulk-fill composite resin build-up), NfPfP (glass-fiber post and dual-cure glass glass reinforced composite resin build-up), NfPt (titanium post and nanohybrid composite resin build-up) and NfPtB (a titanium post bulk-fill composite resin build-up). All teeth were prepared to receive bonded lithium-disilicate ceramic crowns and were subjected to accelerated fatigue testing. Cyclic isometric loading was applied to the incisal edge at an angle of 30O, a frequency of 5Hz, beginning with a load of 100 N (5000 cycles). A 100N load increase was applied each 15,000 cycles. Specimens were loaded until failure or to a maximum of 1,000N (140,000 cycles). Groups were compared using the Kaplan Meier survival analysis (Log rank test at p?0.05). Failure mode was classified in restorable, possibly restorable and catastrophic. None of the tested specimen withstood all 140,000 load cycles. Specimens without ferrule were affected by an initial failure phenomenon (wide gap at the lingual margin between the buildup/crown assembly and the root). There was a significant difference in mean survived cycles between the ferrule groups (73,332 and 73,244 cycles, respectively) and the no-ferrule groups (50,121 cycles; p=0.001). The use of a glass-fiber post was not significant in presence of the ferrule (p=0.884). The no-ferrule groups had similar survival rate (29,649 to 30,987 mean survived cycles until initial failure), except for the NfPfB that showed the highest result (39,761X cycles). However, none of the posts and buildup materials were able to match the performance of the ferrule group (73,244 cycles). In all groups with posts, 100% of failures were unrestorable (catastrophic). The no-post group had 50% of restorable and possibly restorable failures. The survival of broken-down nonvital incisors was improved by the presence of the ferrule but not by the glass-fiber reinforced post.

▼ Abstract: Sucrose is the most cariogenic dietary carbohydrate but in the presence of starch this cariogenicity can be increased. However, conflicting results have been found about the cariogenic potential of starch + sucrose combination to dentin, which may be related to the differences in the models of evaluation used. Most in vitro experiments that evaluated the cariogenic potential of starchy products were made with S. mutans biofilm model, not composed of bacteria involved with the direct or indirect metabolism of starch. In this study, we have expanded the knowledge on this subject using a biofilm model composed of Sm is the most cariogenic oral bacteria, An has amylolytic activity and Sg is an initial colonizer that expresses a binding protein to ?-amylase, which are essential bacteria for the starch metabolism in the oral cavity. The objective of this study was to evaluate the effect of the starch + sucrose combination in root dentin using a tri-species biofilm model, contemplating the salivary amylase activity. An in vitro and blind study was conducted in three independent experiments with n total = 18. Biofilm Sm+Sg+An were grown on bovine root dentin blocks (7x4x1 mm), which surface hardnesses were previously determined. The biofilms were grown in ultrafiltered tryptone and yeast extract broth (UTYEB) containing 0.1 mM glucose and they were exposed to 4 treatment groups: 0.9% NaCl, 1% starch, 10% sucrose or 1% starch + 10% sucrose. The treatments were carried out for 3 min, 8 times per day for 4 days. To simulate the effect of ?¿amylase, biofilms were treated (1 min) with human saliva stimulated before each treatment exposure and salivary amylase was also added into the culture medium. To evaluate the biofilms acidogenicity, the culture pH of culture medium was determined 2x/day, after the 8 treatments exposure and after an overnight period. After 96 h, the biofilms were collected for analyses of bacterial viability, biomass and quantity of polysaccharides. The dentine demineralization was assessed by surface hardness loss (%SHL). The biofilm bio-architecture was qualitatively analyzed by confocal microscopy laser scanning (CLSM). The quantitative data were analyzed by ANOVA followed by Tukey's test at 5% significance level. Biofilms treated with starch + sucrose were more acidogenic (p < 0.05) than those exposed to sucrose alone, showing after the 8 treatments exposure a lower culture medium pH (4.89 ± 0.29 vs. 5.19 ± 0.32). Treatment with starch + sucrose combination provoked greater demineralization (%SHL= 53.2 ± 7.0) than sucrose group (43.2 ± 8.7). Biofilms treated with starch + sucrose did not differ statistically from the sucrose group regarding biomass, bacterial viability and the amount of polysaccharides (p > 0.05). The CLSM analysis suggested that the biofilm formed in the presence of starch + sucrose combination is the most volumous. The findings show additional experimental evidence that starch + sucrose combination is more cariogenic for root dentine than the isolated effect of sucrose Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Cury, Jaime Aparecido, 1947- (advisor), Del Bel Cury, Altair Antoninha, 1948- (coadvisor), Universidade Estadual de Campinas.

▼ Abstract: The restoration of severely broken-down and endodontically-treated incisors (ETI) is a major challenge in daily practice and is commonly undertaken using various types of posts and composite resin buildups. Traditional tooth preparation for post insertion requires substantial amount of hard tissue reduction. With the advent of adhesive dentistry seems to be possible restore endodontically treated incisors without post. The aim of this study is to investigate the adhesive restoration of ETI without ferrule using two type of endocrowns; or ceramic crowns bonded to 3 types of resin core buildups. Article number one used forty-five decoronated endodontically-treated bovine incisors without ferrule (Nf) were divided in 3 groups and restored with various adhesive postless (Np) core-buildups: NfNp using nano-hybrid composite, NfNpB using bulk-fill composite (B) buildup and NfNpFR using fiber-reinforced composite. Previously published data from the same authors about post-and-core buildups (fiber-reinforced post with nano-hybrid composite buildup without ferrule, NfPf group) using the same experimental setup was included for comparison. The second study used thirty decoronated endodontically-treated bovine incisors without ferrule. They were divided in 2 groups and restored with two types of postless CAD/CAM endocrowns using lithium disilicate (Eld) or resin nanoceramics (Erc) blocks. Previously published data from the same authors about lithium disilicate crowns bonded over a post-and-core build-up without ferrule (NfPf) and a 2mm-ferrule (FNp) or ferruless (NfNpFR) core build-ups without post using the same experimental setup were included for comparison. All teeth were prepared to receive bonded crown or endocrown and were subjected to accelerated fatigue testing. Cyclic isometric loading was applied to the incisal edge at an angle of 30O, a frequency of 5Hz, beginning with a load of 100 N (5000 cycles). A 100N load increase was applied each 15,000 cycles.

Failure mode was classified in restorable, possibly restorable and catastrophic. None of the tested specimen withstood all 140,000 load cycles. Even though there were no statistically significant differences between postless experimental groups, the fiber-reinforced core build-up yielded the highest mean cycles to failure (46,023) compared to NfNp and NfNpB (38,899 and 39,751 respectively). NfNpFR also outperformed the post-and-core buildup from the previous study (35,026). There was no statistically significant difference between endocrown materials (Eld with 53,448 and Erc with 52,397; p=0.844). Endocrowns outperformed the group with lithium disilicate crowns on incisors without ferrule and post-and-core build-up (NfPf with 35,025 cycles), had no statistically difference to postless composite resin core build-up (NfNpFR with 45,557 cycles) and had lower survival compared to the group with… Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: In this study, the effect of blasting with different sizes of aluminum oxide particles (Al2O3) on surface quality was evaluated on Y-TZP (yttria stabilized tetragonal zirconia) and bond strength between Y-TZP and resin cement after storage. In Chapter 1, sixty samples of Y-TZP were randomly divided into three groups according to the treatments: control (untreated) and blasting (standoff distance 10 mm, 90° angle, 2.5 bar for 15 seconds) with Al2O3 particles (45 ?m or 150 ?m). To evaluate the contact angle, nine specimens were submitted to Fringe Projection Phase Shifting (FPPS). To quantify the roughness (Ra), the specimens (n = 10) were measured in profilometer (Mitutoyo Surf Test SE 1700) and characterized by the atomic force microscope (MFA) and scanning electron microscope (SEM). The bond strength (BS) was evaluated after 24 hours and 6 months and the failure mode was evaluated in mixed, adhesive or cohesive. The data from Ra and contact angle were subject to one-way ANOVA and Tukey¿s test (? = 0.05) and data from BS was subject to two-way ANOVA) and Tukey¿s test (? = 0.05). Blasting increased the superficial Ra of the Y-TZP (? = 0.0001), however, the alumina blasting had no effect on the contact angle (? = 0.76). The storage time did not affect the RU values (? = 0.1753) but the blasting (? = 0.0004) and the interaction between blasting and storage time (? = 0.02) did. Control and 45?m- blasted groups presented similar values of BS between 24 hours and 6 months-water storage, while the 150?m-blasted group presented the highest value of BS when evaluated in 24h, nonetheless, this bond strength was reduced in presence of water. In Chapter 2, sixty Y-TZP samples were randomly divided into 6 groups according to the surface treatments previously described. Half of the specimens were submitted to mechanical fatigue while the other half was stored for 24 hours for flexural strength test, conducted on a universal test machine and the data of Y-TZP fractured were obtained in Newton, then, converted to Mega Pascal. Phase transformation was analyzed by Micro- Raman spectroscopy and X-ray diffraction (XRD). for characterization of crystals and evaluation of phase transformation. The data from flexural strength were subject to two-way ANOVA Tukey's test (? = 0.05). Blasting increased flexural strength (? = 0.0307); however, the mechanical fatigue decreased it (? = 0.0005). All groups showed presence of tetragonal phase only. Blasting with Al2O3 particles increases Y-TZP flexural strength, but mechanical fatigue decreased this strength without causing phase transformation. Thus, blasting with 45?m particles Al2O3 promoted better flexural strength without causing phase transformation and provided a constant bond strength after 6 months Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Aguiar, Flavio Henrique Baggio, 1977- (advisor), Universidade Estadual de Campinas.

The groups were divided according to the length (11.0, 9.0, 7.0 e 5.0mm) and diameter of the implants (conventional - Ci with 4.0 mm or wide - Wi with 5.0 mm) the groups division was: Ci9 (9.0x4.0mm), Ci7 (7.0x4.0mm ), Ci5 (5.0x4.0mm ), Wi9 (9.0x5.0mm ), Wi7 (7.0x5.0mm ) and Wi5 (5.0x5.0mm ) that was compared to CG (11.0x4.0mm). The influence of prosthesis-implant ratio was analyzed at four levels: 1.2:1; 1.7:1; 2.5:1 and 4.0:1. The models are made representing the anterior section of the mandible, with four cone Morse tape implants and prosthetic components (abutment, bar, retaining screw and dentures - when applicable). The cantilever extension (15mm) was equal for all groups, in both experiments. The load was applied at the end of the cantilever. For the "in vitro" study the shear stress was obtained in 5 peri-implant points around the distal (load side) and the subsequent implant using Fringes® software (load of 0.15 kgf). For the " in silico " test the Maximum Principal Stress was obtained for bone and von Mises stress for implants and prosthetic components using the Ansys Workbench® software (load 100N). The results showed that there is a greater transmission of stress to peri-implant area when smaller implants are used. Implants 5mm long showed different biomechanical behavior when compared to other groups, with higher levels of stress to the bone and implants. Implants with larger diameter decrease the stress in the bone tissue, increasing levels of stress on the prosthetic components. Short implants are responsible for the increase of the stress values in retention screws. The prosthesis-implant ratio favors the increase of stress concentration in the cortical bone, especially for extreme prosthesis-implant ratio (4:1/20:5 mm). Was conclude that despite the increased tension around the implants and prosthetic screws short implants represent an option for rehabilitation of atrophic jaws in order to eliminate grafting procedures, especially when associated with large-diameter implants, except for 5mm implants associated to extreme P:I ratio Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: The use of removable partial denture (RPD) still remains as a viable alternative to an efficient oral rehabilitation. However, due the metal framework lack of esthetic, it has been suggested the use of flexible materials as substitutes to the metal clasps, even thought this material maintains controversial regarding its dimensional properties. In this manuscript, our group compared two materials used in the fabrication of RPD regarding its water sorption and solubility and load transmission by distal extension. For this, poly (methyl methacrylate) (PMMA) and polyamide (POL) discs (n=7) were used to manufacture specimens that were evaluated regarding its water sorption and solubility. For load transmission by distal extension, Kennedy Class I mandibular models were made with photo elastic resin and 3 different RPD were tested: traditional RPD with metal framework and PMMA flange (Control); RPD with metal framework and clasps and flange in POL (POL-Metal); and RPD totally manufactured in POL (TOT-POL). Load of 0.5 and 1.0 kgF were applied to distal extension and the image of the load transmission in the photo-elastic model was captured. Kruskal-Wallis test were used for data analysis. Results showed no statistical difference between both materials regarding water sorption (p=0.6682) and solubility (p=0.4095). Photo-elastic analyses showed higher load transmission by distal extension by both POL group when compared to control group. Within the limitations of this study, it can be concluded that although POL had similar behavior to PMMA regarding water sorption and solubility, the load transmission by distal extension in RPD manufactured with POL shows the worst results, but clinical studies should de done with this material to indicates its use Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Silva, Wander José da, 1980- (advisor), Del Bel Cury, Altair Antoninha, 1948- (coadvisor), Universidade Estadual de Campinas.

▼ Abstract: Reinforced glass-ceramics represent a promising alternative to metal ceramics and high-strength polycrystalline ceramics for prosthetic rehabilitation due to a combination of favorable mechanical and optical properties. Such features have supported the fabrication of monolithic crowns, without requiring a veneering ceramic. It has been shown that monolithic rehabilitations present higher resistance when compared to conventional prostheses, which has also supported the fabrication of reduced-thickness restorations. The zirconia-reinforced lithium silicate (ZLS) ceramic system was recently introduced on the dental market, and its fatigue fracture behavior and survival predictions have not been addressed yet. Thus, this study investigated the reliability and failure mode of monolithic ZLS crowns of different thicknesses. Monolithic molar crowns of different thicknesses (1.5 mm, 1.0 mm, and 0.5 mm) were modeled and milled through ZLS blocks (n=21/group) using a CAD/CAM system. The crowns were cemented on epoxy resin replicas (G10) due to its similar properties to dentin. Single load-to-failure test was performed to determine the step-stress profiles (mild, moderate and aggressive) (n=3/group). Then, 18 specimens of each group were allocated in the step-stress profiles and the accelerated fatigue test was performed by sliding an indenter 0.7 mm lingually down on the distobuccal cusp until specimen fracture or suspension. Characteristic failure load for each thickness was calculated (90% two-sided confidence interval). Use level probability Weibull curves and reliability for missions of 100,000 cycles at 100, 200, 300, 400, 600 and 800 N cycles were plotted and calculated (90% two-sided confidence interval). Fractured specimens were analyzed using a polarized-light optical microscope and scanning electron microscopy (SEM) to characterize fracture patterns. Beta (ß) values greater than 1 for all ZLS crown thicknesses suggest that the damage accumulation due to fatigue was an acceleration factor for failure. Characteristic failure load levels were 1,571 (1,479 - 1,668) N for 1.5mm-thickness ZLS crown, followed by 1,121 (1,028 - 1,222) N for 1.0mm-, and 750 (604 - 932) N for 0.5mm-thickness. While 0.5 mm ZLS crowns exhibited a significant reduction in the reliability at 200, 300 and 400 N mission loads (69%, 41% and 19%, respectively), no significant difference was observed between 1.0 mm and 1.5 mm crowns, with both thicknesses maintaining the probability of survival at approximately 90%. Failure primarily comprised bulk fracture where critical radial cracks originated from the cementation surface beneath the indenter loading trail and propagated towards the cervical margin of the crown. Accordingly, 1.5mm- and 1.0mm-thickness monolithic ZLS crowns presented higher probability of survival compared to 0.5mm crowns. Bulk fracture was the chief failure mode, regardless of thickness Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: The bioactive behavior in dental materials has been investigated in several dentistry field. Some studies have successfully modified dental ceramics by adding bioactive glass (BG), making those materials able to exhibit a bioactive behavior. However, those compositions have presented poor mechanical properties which could be related to an inappropriate thermal treatment. Additionally, other properties as chemical solubility, hardness, surface roughness and color stability, which may be affected, have not been tested. Thus, the objective of this study was to evaluate the physical and mechanical properties of a leucite-reinforced glass ceramic modified by bioactive glass. For this, different compositions of dental ceramic (DC) modified by 58S bioactive glass were synthesized by sol-gel method (BG20: 80wt% DC + 20wt% BG, BG30: 70wt% DC + 30wt% BG and BG40: 60wt% DC + 40wt% BG). First, the compositions were characterized by differential scanning calorimetry and had its biaxial flexural strength assessed after different sintering temperature (910, 950, 1000 and 1050 °C). A 100wt% DC group sintered according to the manufacturer¿s recommendation (910 °C) was used as a control group. The sintering temperature that promoted the highest flexural strength values for each composition (BG20 at 950 °C, BG30 at 1000 °C and BG40 at 1050 °C) were used to evaluate the bioactive behavior, chemical solubility, microhardness, surface roughness and color stability. To investigate the bioactive behavior, the groups were evaluated by X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) with and without Simulated Body Fluid (SBF) immersion for 21 days. For microhardness (n=5), the groups were evaluated by a microhardness tester with a Knoop indenter Knoop. Chemical solubility (n=10) was evaluated by immersion in 4% acetic acid solution for 16 hours, surface roughness (n=10) by a 3D optical profiler and color stability (n=10) by CIEL*a*b* system. Experimental groups showed indication of bioactive behavior with SBF immersion. All the experimental groups presented flexural strength lower than the control group (p < 0.05; ANOVA/Tukey¿s test) and were similar among them. The hardness was only higher in the BG40 group compared to the control group. The chemical solubility increased with the increase of the BG content in the compositions. On the other hand, the surface roughness and color stability tend to be better in the groups with major BG amount. No experimental composition was able to obtain desirable results in all properties studied. More studies need to be performed so that the composition and heat treatment could contribute to suitable mechanical performances allied a balance between bioactive behavior and chemical solubility as well as low surface roughness and low color change Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: The prosthetic complications usually involve the abutment-screw integrity, where the abutment¿s screw is the most affected component. Thus, the study of surface treatments in order to improve the material¿s mechanical behavior might contribute to increase the long-term success follow-up. The aim of this study was to assess the influence DLC (Diamond-like Carbon) deposition method at the abutment¿s screw on the mechanical behavior of single implant-supported restorations. For this, seventy-five abutment¿s screws were allocated into three groups according to the DLC surface treatment method of deposition (25/group): CTRL: control (no treatment); RFPA (Radio Frequency Plasma-activated) (experimental group); UMS (Unbalanced Magnetron Sputtering) (experimental group); First, twelve screws (n=4/group) were characterized by nanoindentation testing, where the nanohardness and Young¿s modulus were measured by nanoindentation testing at the coated and not-coated groups. Data were statistically evaluated through linear mixed models. The Young¿s modulus previously measured were used to conduct a finite element analysis (in silico). Then, a square block (5 x 5 x 10mm) was constructed to simulate a titanium substrate; Onto the block, a 4 µm-thick surface coating and a counterpart were modeled. Three groups were obtained according to the DLC Young¿s modulus properties: CTRL (control - no DLC coating), UMS and RFPA. A 30 N-load was applied into the counterpart based on a screw thread cross-section to simulate the screw tightening. The shear stress (MPa) and deformation (µm) were measured considering two locations: loading face and interface between substrate and coating. For the step-stress accelerate life-testing (in vitro), twenty-one screws were connected into customized abutments and then into external hexagon implants (4.0 x 10mm). All screws were tightening with the same tightening force (30N) using a digital wrench and following the manufacture¿s instruction. Three samples of each group were undergone to the uniaxial compression testing until failure. The mean load-to-fracture were used to design the step profiles as followed: mild (n=9/group), moderate (n=6/group) and aggressive (n=3/group) according to the speed rapidness increase. The use of level probability Weibull curves and reliability for a given mission of 50,000 and 100,000 cycles at 100 N, 150 and 200N were calculated. The most representative fractured samples were observed under scanning electron microscopy (SEM) to fractography characterization. According to the nanoindentation results, both DLC groups showed higher nanohardness than control (p<.01). The UMS showed higher elastic modulus than Ctrl and RFPA (p=.00). There was no difference between the elastic modulus of CTRL and RFPA (p>.05). The in silico analysis showed that, the higher the Young¿s modulus the greater the shear stress at interface between substrate and coating. Regarding the fatigue testing, the CTRL and RFPA showed ß<1, (ß =0.68 and ß=0.62, respectively), indicating that failures were… Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.

▼ Abstract: In this study was verified the accuracy and porosity of denture submitted for double cycles of polymerization. Thirty six mas ter cast were made in dental stone from the impression of metal die. These master cast were divided by three groups of 12 elements each. Denture bases of conventional acrylic resin were made on the casts of the groups I e II (GI and GIl), polymerized in water bath duril1g 9 hours at 730C, and specific resin for denture bases for microwave polymerization were made on the casts of group III (GllI) and cured in microwave oven at 500W during 3 minutes. The accuracy was verified by the weight of a impression material was put between the denture base and cast die under load of 2 Kg. Afterwards, all the denture bases were relining by addition method, and those of the group 1 and III were relined with the same material and polymerization tech.l11c. The denture bases of the group II were filled with the same resin, however cured in microwave oven with 500W during 3 mil1utes. The accuracy was revaluable by the same way as described above. The porosity, was verified by the immersion of the polish specimens in a solution of pennanent black i.nk and the pores were counted through a stereo light microscope with under magnification of 6,3 x. The average and standard deviation gotten for an accuracy before and after the relinil1g were respectively: G 1: 0,632 + 0,024 - 0,659 + 0,026; G2: 0,632 + 0,033 - 0,677 + 0,031; G3: 0,580 + 0,018 - 0,798 + 0,049. There was a significant difference only for the group TIl. The average and standard deviatio.l1 for the porosity before and after the relining were respectively: Gl = 8,33 + 0,63 - 9,25 + 0~85; G2 = 8,17 + 0,98 + 10,08 + 1,63; G3 = 5,42 + 0,78 - 6,58 + 1,02. The concluslon is that the conventional resin when polymerizated in the fust cycle by conventional method and in the second cycle by microwaves energy showed similar accuracy to conventional relining. ln relatiori to the porosity was verified that as after the fust and second cycle of polymerization, the conventional resin showed the highest number of pores Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Del Bel Cury, Altair Antoninha, 1948- (advisor), Universidade Estadual de Campinas.
