▼ The bilayer tablet contains two layers of materials. However, such tablets have higher tendency to crack at the interface or even layer separation. Interfacial bonding strength (IBS) is the strength that bonds two layers at the interface. Understanding the mechanism of forming an adequate IBS is critical to the successful development of a bilayer tablet product. The first step is to establish a standard measuring method for obtaining accurate IBS. Both shear and tensile tests are commonly used to measure IBS, which shows a linear correlation. However, the shear test has a more complicated result due to complex stress application and tablet testing orientation, which is not an issue for the tensile test. Therefore, the tensile test is preferred for straightforward data interpretation because of uniform applied stress. Thus, the tensile strength becomes a standard method for measuring IBS. IBS of four layer combinations between microcrystalline cellulose (MCC) and lactose 24AN (Lac), i.e., MCC/MCC, Lac/Lac, MCC/Lac and Lac/MCC (1st/2nd), were measured under various first layer (P1) and second layer compaction pressures (P2) to validate the hypothesis that IBS is controlled by bonding area (BA) and bonding strength (BS) interplay at the interface. BA is the contact area between first layer and second layer powders at the interface and BS is the strength interactions over the contact area. As a result, any factors that influence either BA or BS affect IBS. Moreover, differential radial expansion between layers also affects IBS. In this work, BA is assessed by surface waviness and tablet porosity, while BS is assessed by tablet strength at zero porosity. Lower P1 leads to higher porosity of the first layer and higher P2 generally leads to greater surface waviness at the interface, both leading to larger BA and, thus, higher IBS. However, higher P2 causes a larger difference in radial expansion when two layers are different materials, which weakens IBS. The materials in the two layers determine BS, which follows the descending order of MCC/MCC > MCC/Lac (Lac/MCC) > Lac/Lac. The trends in the effects of these factors on measured IBS support the hypothesis. Further, bilayer tablets with each layer containing the mixture of MCC and lactose in different ratios with/without hydroxypropyl methylcellulose (HPMC) K15M are studied to understand the compositional effect on IBS under two P1s (20 and 100 MPa) and a fixed P2 of 200 MPa. The multi-component bilayer tablets make the trend of IBS more complicated as a function of MCC content. Still, IBS changes can be explained by the BA and BS interplay. The increase of MCC can increase BS but, at the same time, decrease BA. The addition of HPMC decreases BS for lower IBS. The interplay between BA and BS will determine IBS. Particle size is also an important factor to affect IBS. Two sizes of microcrystalline cellulose (MCC) and lactose anhydrate were prepared to study the effect of particle size on IBS of bilayer tablets. The effect of particle size on IBS is also influenced by…

▼ Adequate mechanical strength is a critical requirement to the successful development of a tablet product. Before tablet compression, powders are often engineered by various processes including wet granulation and surface coating, which may improve or adversely affect the powder tableting performance. Such effects, commonly, result from a change in either particle mechanical properties or particulate (size, shape) properties. In this work, tableting performance is interpreted based on the qualitative bonding-area and bonding-strength (BABS) model. The tabletability of the microcrystalline cellulose (MCC) granules deteriorates rapidly with increasing amount of granulating water and eventually leads to over-granulation at high water level. Granule surface smoothing, size enlargement, granule densification and shape rounding are the dominant factors leading to the tabletability reduction of plastic MCC. Incorporation of increasing amounts of brittle excipients, such as lactose or dibasic calcium phosphate reduces the rate of tabletability reduction by promoting more granule fragmentation, introducing more surface area available for bonding. When a sufficient amount of brittle excipients is used, the over-granulation phenomenon can be eliminated. Surface coating of incompressible MCC pellets with highly bonding polymer leads to sufficient surface deformation and adhesion to enable direct compression of the pellets into tablets of adequate mechanical strength. This improvement is enhanced by the presence of moisture, which plasticizes the polymer to allow the development of a larger bonding area between coated pellets. The relationship between mechanical properties and tableting behavior is systematically investigated in polymeric composites using celecoxib-polyvinylpyrrolidone vinyl acetate solid dispersions. Mechanical properties such as indentation hardness of the solid dispersions were measured using nanoindentation. Incorporation of celecoxib up to 60% by weight hardens the polymers, which reduces bonding area but increases bonding strength. On the other hand, moisture softens the solid dispersions and facilitates deformation under pressure to improve tablet mechanical strength. In summary, insights into the deteriorated tabletability of wet granulated powders have been developed and strategies for improving tabletability have been demonstrated. Also, the relationship between particle mechanical properties and tableting performance has been examined using solid dispersions. The BABS model has been further developed to enable its widespread application in interpreting complex tableting behavior.

MICROTENSILE BOND STRENGTH OF NEW PASTE/PASTE RESIN-MODIFIED GLASS IONOMER CEMENT SYSTEMS: THE EFFECT OF DENTIN PRETREATMENT by Yasser Fawaz Al-fawaz Indiana University School of Dentistry Indianapolis, Indiana Background: In order to improve the clinical performance of RMGIC 3M ESPE and GC America introduced paste/paste resin-modified glass ionomer cements, Ketac™ Nano and Fuji Filling™ LC, respectively. Both companies developed non-rinse substrate conditioners (i.e., Ketac Nano Primer-3M ESPE and GC Self-Conditioner-GC America) that should be used with these new materials instead of the conventional polyacrylic acid. It has been also advised by both manufacturer’s to use this novel substrate conditioner with the previously marketed RMGICs. Objective: to investigate whether the use of novel non-rinse conditioners (i.e., Ketac Nano Primer 3M ESPE and GC Self Conditioner GC America) as substrate pre-treatment and the new paste/paste resin-modified glass-ionomer cement, RMGIC (Ketac™ Nano 3M ESPE and Fuji Filling™ LC GC America) would affect the microtensile dentin bond strength (µTBS) of the material when compared to the traditional RMGIC with polyacrylic acid as a surface substrate pre-treatment. Materials and Methods: 96 extracted non-restored human molar were sectioned to expose occlusal dentin. Dentin surface was finished with SiC paper to standardize the smear layer. Bonding protocols of the different materials to dentin were performed following the use of two dentin conditioners. Eight groups (n=12) were tested: G1: Ketac Nano Primer + Ketac Nano, G2: Ketac Conditioner + Ketac Nano, G3: Ketac Nano Primer + Photac Fil, G4: Ketac Conditioner + Photac Fil, G5: GC Self Conditioner + Fuji Filling LC, G6: GC Cavity Conditioner + Fuji Filling LC, G7: GC Self Conditioner + Fuji II LC and G8: GC Cavity Conditioner + Fuji II LC. The specimens were stored in 37°C for 24h in 100% humidity before cutting non-trimmed beams for the µTBS with cross-sectional areas of approximately 0.8 × 0.8 mm2. Nine beams were used from each specimen. Test was done using universal testing machine at a cross-head speed of 1mm/min. Debonded specimens were examined under a stereomicroscope at 45× magnification to evaluate the failure mode. Eight randomly chosen representative debonded beams were imaged under a scanning electron microscope (SEM). Results: µTBS in MPa (mean ± SE) were: G1: 9.5±1.0, G2: 11.0±1.0, G3:20.0±1.0, G4:16.8±0.9, G5: 15.1±1.0, G6: pre-test failure, G7: 20.0±1.0, G8:14.1±0.9. Weibull-distribution survival analysis was used to compare the differences in microtensile peak stress among the groups. Group5 has cohesive predominant faultier mod while the other groups have adhesive predominant failure. Conclusion: Within the limitations of this study, the use of the novel non-rinse conditioners did not improve the microtensile bond strength of new paste/paste RMGIC to dentin. In fact, the use of the novel non-rinse conditioners enhanced the bond…

▼ Orthodontic attachments must be able to bond to a wide range of tooth and prosthetic surfaces. Despite the high prevalence of fluorosis in many parts of South Africa (Louw A, Chikte U 1997), only limited information is available on the integrity of the bond between orthodontic brackets and fluorosed teeth. The objective of this study was to measure and compare Shear Bond Strengths (SBSs) of metal and ceramic orthodontic brackets on fluorosed and non-fluorosed teeth. One hundred and twenty (60 fluorosed and 60 non-fluorosed) extracted premolar teeth were divided into four groups A to D, consisting of 30 teeth in each group. BluGloo® was used as an orthodontic adhesive to bond brackets on the buccal surface of each tooth. The experimental groups consisted of Group A, in which Nu-Edge® metal brackets were used and Group B, in which InspireIce® ceramic brackets were bonded to fluorosed teeth. Group C and D consisted of Nu-Edge® metal brackets and InspireIce® ceramic respectively, bonded to non-fluorosed teeth. Bonding techniques were kept the same and standardised for all four groups. An Instron testing device was used to debond and measure the SBSs. SBSs were compared using ANOVA with posthoc analysis done using Dunnett’s C test for pairwise comparisons. Significance was set at P<0.05. The results showed that SBS of Group B>Group C>Group D>Group A. Ceramic brackets bonded to fluorosed teeth had the highest SBS with a mean of 15.78 (SD=9.07) Megapascals (MPa), while metal brackets bonded to fluorosed teeth produced the lowest SBS of 8.41 (SD=4.68) MPa. The SBSs of ceramic brackets bonded to fluorosed teeth was significantly higher than that of SBS of metal brackets bonded to fluorosed teeth, but not significantly different from SBSs obtained from either brackets bonded to non-flurosed teeth. The BluGloo adhesive if used to bond ceramic brackets to fluorosed teeth can produce adequate SBS for clinical use. The recommendation from this study is that ceramic brackets can be used efficiently to bond to fluorosed teeth. A follow up study should be carried out to assess the nature of enamel damage caused during debonding of flourosed teeth. This is a laboratory study and thus the clinical application should be interpreted with caution. Advisors/Committee Members: Dawjee, S.M. (advisor).

▼ Interface bonding between pavement layers is a key factor affecting the performance of any pavement structure. Over the years, several studies have been performed to better understand bonding between pavement layers. The first phase of this study was a laboratory assessment, which analyzed different parameters to better characterize the interlayer bond in pavements. Phase 2 of the study was a field validation and evaluation. This thesis, based on the results of phase 2, focuses on optimizing in-situ tack coat application rate and field installation. The main objectives of phase 2 were to validate the lab-determined optimum residual application rate for tack coat materials on a milled hot-mix asphalt (HMA) surface and to evaluate field performance of tack coat materials. Several parameters were analyzed, including the cleaning method prior to tack coat application, the paving procedure, tack coat type, and existing pavement surface texture. Tack coat materials used were SS-1h, SS-1hp, and SS-1vh (non-track tack coat). For the cleaning methods, the conventional procedures, broom and vacuum, were used on most of the sections and were compared to air-blast cleaning. Two paving procedures were studied: the conventional paving method using a distributor truck and a regular paver, and the spray paver, which applies tack coat and paves at the same time. Twenty-six sections were constructed on Interstate 80 in Illinois, and 19 sections were built on Illinois Route 98. The Interstate 80 test sections were constructed on three existing pavement surfaces: milled HMA, milled Portland cement concrete (PCC), and fresh binder stone mastic asphalt (SMA). Two tests were used to analyze interface bonding: the interface shear test and the torque bond test. The test section on Illinois Route 98 was constructed on a milled surface. All specimens were cored in the field and tested at the Illinois Center for Transportation (ICT) using the Interface Shear Test Device (ISTD). The results showed similar bond strength for the two types of cleaning methods; however, air-blast cleaning required use of a lower optimum residual application rate in the field to achieve the same bond strength. The bond strength at the interface when tack coat was applied with a spray paver is similar to the bond strength achieved when a conventional paver was used. The optimum residual application rate for milled surfaces obtained from the laboratory was 0.06 gal/yd2 (0.27 L/m2). This rate was validated at both test sites. The optimum residual application rate obtained for fresh binder SMA was 0.02 gal/yd2 (0.09 L/m2). SS-1vh performed better than any other tack coat material studied, and SS-1hp performed better than SS-1h. iii Identification of the optimum tack coat application rate will help ensure cost-effective and efficient tack coat application and will enhance pavement performance. It will also help the industry to better optimize resources and improve pavement performance. Advisors/Committee Members: Al-Qadi, Imad L. (advisor).

▼ Thermosonic ball bonding is a key technology in electrical interconnections between an integrated circuit and an external circuitry in microelectronics. Although this bonding process has been extensively utilised in electronics packaging industry, certain fundamental aspects behind all the practice are still not fully understood. This thesis is intended to address the existing knowledge gap in terms of bonding mechanisms and interfacial characteristics that are involved in thermosonic gold and copper ball bonding on aluminium pads. The research specifically targets the fine pitch interconnect applications where a thin metal wire of approximately 20 µm in diameter is commonly used. In thermosonic ball bonding process, a thin gold or copper ball formed at the end of a wire is attached to an aluminum pad through a combination of ultrasonic energy, pressure and heat, in order to initiate a complex solid-state reaction. In this research, the mechanisms of thermosonic ball bonding were elaborated by carefully examining interfacial characteristics as the results of the bonding process by utilising dual-beam focused ion beam and high resolution transmission electron microscopy, including the breakdown of the native alumina layer on Al pads, and formation of initial intermetallic compounds (IMCs). The effect of bonding parameters on these interfacial behaviours and bonding strength is also investigated in order to establish an inter-relationship between them. Interfacial evolution in both Au-Al and Cu-Al bonds during isothermal annealing in the temperature rage from 175ºC to 250ºC was investigated and compared. The results obtained demonstrated that the remnant alumina remains inside IMCs and moves towards the ball during annealing. The IMCs are formed preferentially in the peripheral and the central areas of the bonds during bonding and, moreover, they grow from the initially formed IMC particles. Growth kinetics of Cu-Al IMCs obey a parabolic growth law before the Al pad is completely consumed. The activation energies calculated for the growth of CuAl2, Cu9Al4 and the combination (CuAl2 + Cu9Al4) are 60.66 kJ/mol, 75.61 kJ/mol, and 65.83 kJ/mol, respectively. In Au-Al bonds, Au-Al IMC growth is controlled by diffusion only at the start of the annealing process. A t⁰.2-0.3 growth law can be applied to the Au-Al IMC growth after the Al pad is depleted. The sequence of IMC phase transformation in both Au-Al and Cu-Al bonds were investigated. Voids in Au-Al bonds grow dramatically during annealing, however, only a few voids nucleate and grow very slowly in Cu-Al bonds. The mechanisms of void formation, including volumetric shrinkage, oxidation and metal diffusion were proposed and discussed.

Indiana University-Purdue University Indianapolis (IUPUI)

In adhesive dentistry, obtaining a good bond is a fundamental goal. It has been suggested that filler addition to the adhesives would increase the bonding strength of the adhesive layer. Halloysite aluminosilicate nanotubes (HNTs) are biocompatible, hydrophilic, durable, and have high mechanical strength. These advantages make them good candidates to be used as reinforcing agents for improving the properties of dental adhesives. The objective of this study was to evaluate the effect of incorporating HNTs into a commercial two-step etch-and-rinse adhesive system or one-step self-etch adhesive system on dentin shear bond strength. HNTs were incorporated into the two commercial adhesive systems in 0 wt%, 5 wt%, 10 wt%, and 20 wt%. The commercial control adhesives and the experimental adhesives were used to bond occlusal dentin of 120 extracted human molar teeth and then tested for shear bond strength by a universal testing machine with a semi-circular edge at a crosshead speed of 1.0 mm/min. Debonded specimens were examined under light microscopy to evaluate the fracture pattern. Resin-dentin interface were evaluated under scanning electron microscopy (SEM) after bonding dentin slabs using commercial control adhesives and experimental adhesive that showed numerically highest shear bond strength from each adhesive system. Two-way ANOVA was used to evaluate the effects of adhesive system and nanofiller content on shear bond strength. Pair-wise comparisons between groups were made using Fisher's (LSD) (p < 0.05). For the self-etch adhesive system, only incorporation of 5 wt% showed a significant increase in shear bond strength to dentin compared with the commercial control group. For the etch-and-rinse adhesive system, there was no significant difference in shear bond strength between HNTs filled adhesives groups and the commercial control group. Resin-dentin interface SEM evaluation showed nanotubes infiltrated into dentinal tubules. In conclusion, incorporating the self-etch adhesive system with 5 wt% HNTs increased the bond strength to dentin. Incorporation of up to 10 wt% filler concentration into both the self-etch and the etch-and-rinse adhesive systems did not adversely affect the bond strength to dentin or the handling properties. HNTs can penetrate along with resin tags into dentinal tubules, which could expand the use of their unique properties.

Purpose: With the recent advent of many 1-step adhesive systems, clinicians’ preference have also been shifting to these systems in the clinics, although, these adhesives are being reported to produce lower bond strength compared to 2- or 3-step adhesives. Most of the 1-step adhesives are universal adhesives usable either in a self-etching mode or in a total-etching mode with a prior phosphoric acid etching step. Furthermore, bond strength of total-etch adhesives to moist dentin was found to be higher than that of dry dentin in a number of studies. The purpose of this study was to evaluate the bond performance of an universal adhesive to dentin in different etching strategies using micro-tensile bond strength (μTBS) to dentin, SEM and TEM. Methods: Two adhesive systems used were, CLEARFIL Universal Bond (CUB) and 2-step self- etch adhesive CLEARFIL Mega Bond (CMB). K-ETCHANT Syringe (Ech) was used as an etching agent. Flat dentin surfaces of human molars were exposed and polished using600 SiC paper under running water. The prepared dentin surfaces were then subdivided into the following four groups: MB (CMB in self-etch mode)- the control, NE (CUB without Ech), ED (CUB applied in dry conditions following Ech) and EW (CUB applied in wet conditions following Ech). After resin composite build-up, each specimen was sectioned after water storage at 37°C for 24 hours to obtain beams with a bonded area of 1 mm2. µTBS test was performed at a cross-head speed of 1mm/min using half of the beams from each group. Rest of the beams was tested after 6 months. The data were analyzed by one-way analysis of variance and Tukey’s test. Results: Only ED showed significantly lower µTBS after 6 months compared to its 24 hours counterpart. There was no significant difference between the 4 groups in both 24 hours and 6 months. CUB showed stable adhesion durability regardless of the strategies. Conclusion: CLEARFIL Universal Bond (CUB) showed sufficient dentin bond strength in both self-etch and total-etch strategies. In terms of bond durability, wet bonding to acid-etched dentin may be preferred over bonding to dry acid-etched dentin.

▼ Bi-material interface is often observed in many advanced materials and structures. Measurement of the interface bonding strength is more challenging than the measurement of pure tensile or shear strength of a homogeneous material because of the presence of the stress singularity at the interface corner, non-uniform stress distribution along the interface and the co-existence of normal and shear stress components. In this PhD research project, a new innovative test method including specimen design, test procedure and an iterative calculation algorithm, is developed for more accurate determination of the interface bonding strength. Three different types of bi-material interface are considered in this study; interface between elastic and elastic materials, elastic and viscoelastic materials, and viscoelastic and viscoelastic materials. Analytical solutions are developed to determine the stress singularity and conditions for its elimination for all the above three types of interface. The analytical solution for the elastic/elastic bi-material interface is derived based on the axi-symmetric asymptotic analysis. For the elastic/viscoelastic and viscoelastic/viscoelastic bi-material interfaces, the analytical solutions are obtained from the solution of elastic/elastic interface through the elastic-viscoelastic correspondence principle. The developed analytical solutions are verified by FEM numerical analyses. The elastic properties of materials are determined through uni-axial tensile tests and the viscoelastic properties are by relaxation tests. It is found that the order of the stress singularity changes with time due to the viscoelasticity of materials. If any stress singularity exists at the interface corner, with time the order of singularity increases. For a non–singular case, the stress singularity may increase or decrease with time, depends on the specimen geometry. With the developed design that can eliminate the stress singularity at the interface corner, the loading capacity of the specimen is also increased. For example, the tensile load carrying capacity of such designed aluminum/epoxy bonded joint is increased by 2.65 times than that of the ASTM (American Society for Testing and Materials) butt joint design. Finally, as a practical application of this research, the optimal ranges of bonding angles at the interface corners of porcelain fused to metal (PFM) dental crowns with precious or non-precious metal alloys are suggested.

Este estudo objetivou avaliar o efeito do armazenamento em água na resistência de união [μTBS] de diferentes abordagens de adesão à dentina. As superfícies oclusais de 24 terceiros molares hígidos foram cortadas, planificadas e, a smear layer padronizada. Os dentes foram divididos aleatoriamente em 4 grupos de acordo com a abordagem de união, ou seja, convencionais, de 3 passos (Adper Scotchbond Multi-Purpose, 3M ESPE - SBMP) e, de 2 passos (Adper Single Bond 2, 3M ESPE -SB); autocondicionantes, de 2 passos (AdheSE, Ivoclar/Vivadent - AD) e, de 1 passo (Adper Prompt L-Pop, 3M ESPE - LP). Após o procedimento adesivo (n=6) os dentes foram restaurados pela técnica incremental com resina composta Filtek Supreme XT (3M ESPE). Obteve-se 240 espécimes em forma de palitos com área aproximada de 0,8 mm2. Dos espécimes obtidos para cada grupo (n=60), metade foi submetido ao teste de resistência de união imediato [IM] (n=30) e, a outra metade foi armazenada em água para realização do teste após 6 meses de armazenamento [6M](n=30). A ANOVA 2 fatores e o pós-teste de Tukey mostraram que não ocorreu degradação após 6M, exceto para o SB, ainda assim, a maior média da resistência de união IM e 6M foi do SB (49.13 e 40.27 MPa). O LP mostrou as menores médias nos dois períodos de avaliação (18.35 e 18.34 MPa). O AD e o SBMP apresentaram desempenho intermediário. Entretanto, o SB apresentou redução significativa da resistência de união após 6M, apesar disso, obteve os melhores resultados. Concluiu-se que embora ocorreu uma degradação significativa para o SB, este sistema foi o que apresentou maior μTBS após 6 meses de armazenamento em água. O teste de microtração não foi sensível para detectar a degradação dos sistemas adesivos com valores mais baixos de μTBS.

The purpose of this study was to evaluate the effects of water storage on resindentin bond strengths [μTBS] formed by different adhesive bonding approaches. A flat superficial dentin surface the 24 human third molars were exposed and polished to create a standardized smear layer. The teeth were randomly distributed into four different: total-etch 3 step (Adper Scotchbond Multi-Purpose, 3M ESPE - SBMP), and total-etch 2 step (Adper Single Bond 2, 3M ESPE - SB); self-etch 2 step (AdheSE, Ivoclar/Vivadent - AD); and self-etch 1 step (Adper Prompt LPop , 3M ESPE - LP). Following the adhesive application (n=6), resin composite crowns were incrementally placed (Filtek Supreme XT - 3M ESPE) in order to obtain bonded sticks, with a cross-sectioned area of about 0,8 mm2. The bonded sticks were randomly divided and assigned to be tested immediately [IM] (n=30) or after 6 months of water storage [6M](n=30). Two-way ANOVA and Tukeys test showed that none of the adhesives showed degradation after 6 months, except SB, which was the one that achieved the highest μTBS either in the immediate time (49.13 MPa) and after 6 months (40.27 MPa). LP showed the lowest μTBS in both periods of evaluation (18.35 and 18.34 MPa). AD and SBMP showed intermediate…

O objetivo deste estudo foi avaliar o efeito da aplicação vibratória de adesivos autocondicionantes simplificados na resistência de união à dentina e nanoinfiltração, tanto no tempo imediato como após 6 meses de armazenamento em água. A superfície oclusal de trinta terceiros molares foi desgastada até obtenção de uma superfície plana de dentina. Três sistemas adesivos autocondicionantes de 1 passo (One Coat 7.0 [OC], Coltène Whaledent; Clearfil S3 Bond [CS], Kuraray e FuturaBond NR [FB], Voco) foram aplicados de forma suave (SU) ou vibratória (VB) (n=5). Após a construção de coroas de resina composta (Opallis, FGM), os espécimes foram armazenados durante 24 h em água destilada a 37 C. Ao término deste período os espécimes foram cortados longitudinalmente nas direções x e y para conseguir palitos com seção transversal de 0,8 mm2. Os espécimes foram testados sob tração (0,5 mm/min) no tempo imediato [IM] ou após 6 meses de armazenamento em água [6M]. Dois espécimes de cada dente nos respectivos períodos de armazenamento foram imersos por 24 h em uma solução 50% por peso, revelados (8 h) e analisados em microscopia eletrônica de varredura. A quantidade de penetração de nitrato de prata na interface adesiva foi medida no software ImageTool 3.0. Os dados de cada adesivo provenientes de cada teste foram submetidos a uma análise de variância de dois fatores (Forma de Aplicação vs. Tempo) e teste de Tukey (α=0,05) para contraste das médias. Maiores valores de resistência de união e menor deposição de nitrato de prata foram observados no tempo imediato e nos grupos de aplicação vibratória para os adesivos OC e CS. FB apresentou baixos valores de resistência de união independente do tipo de aplicação. Pode-se concluir que a aplicação vibratória pode aumentar os valores de resistência de união dos adesivos One Coat 7.0 e Clearfil S3 Bond retardando o processo de degradação destas interfaces.

The purpose of this study was to evaluate the effect of different application modes on the immediate and 6-month resin-dentin bond strength and silver nitrate uptake. Three one-step self-etch adhesive systems (One Coat 7.0 [OC], Coltène Whaledent; Clearfil S3 Bond [CS], Kuraray and FuturaBond NR [FB], Voco) were applied in a flat superficial dentin surface of thirty human molars under slight [S] or vibratory [V] application modes. Composite build-ups (Opallis, FGM) were constructed incrementally. After water storage at 37 C for 24 h, teeth were sectioned to obtain sticks with cross-sectional area of 0.8 mm2 to be tested in tension (0.5 mm/min) either immediately [IM] or after 6 months [6M] of water storage. Two bonded sticks from each tooth at each storage time were immersed in a 50% (w/v) solution of silver nitrate (24 h), photo-developed (8 h) and analyzed under SEM. The silver nitrate uptake was measured using the ImageTool 3.0 software. The data from each adhesive were analyzed by two-way ANOVA and Tukeys test (α = 0.05). The adhesives OC and CS showed higher resin-dentin bond strength values and lower silver nitrate…

Objetivo: Este estudo objetivou avaliar a radiopacidade, resistência máxima à tração,(RMT), microdureza (KHN), grau de conversão (GC), sorção de água (SA),solubilidade (SO), resistência de união (μTBS) de sistemas adesivos experimentais pela adição de nanopartículas de zircônia ou micropartículas de vidro de bárioborosilicato. Material e métodos: Dez sistemas adesivos experimentais com diferentes concentrações de nanopartículas de zircônia [0(EX0), 15(EX15), 25(EX25), 35(EX35) e 50%(EX50) ou com micropartículas de óxido de bário-borosilicato [0(R0), 30(R30), 40(R40), 50(R50) e 60%(R60)] foram formulados tendo como base o sistema adesivo Ambar (FGM). O sistema adesivo Adper Single BondTM 2 (SB, 3M ESPE) foi utilizado como referência comercial. Foram confeccionados espécimes de adesivo para os testes de radiopacidade (n=5), KHN (n=5), SA (n=10) e SO (n=10) utilizando matriz metálica com 5,0 mm de diâmetro e 1,0 mm de profundidade e, para a RMT (n=5) uma matriz metálica com 10 mm de comprimento, 2 mm de largura, 1 mm de profundidade e, área de sessão transversal de 0,8 mm2. Os espectros FTIR foram obtidos de espécimes não polimerizados e polimerizados dos adesivos para determinar o GC dos materiais. Para μTBS, aplicou-se os adesivos na superfície de dentina de dentes molares humanos (n=7). Os dentes foram reconstruídos com resina composta e cortados para obtenção de espécimes em forma de palitos que foram testados imediatamente (IM) ou após 6 meses de armazenamento em água (6M). Os dados foram submetidos a ANOVA e pós-teste de Tukeys (α=0,05). Resultados:Todos os sistemas adesivos experimentais mostraram radiopacidade semelhante a do esmalte dental. Apenas o R60 mostrou valores de RMT mais elevado que os outros materiais. Os sistemas adesivos experimentais apresentaram valores mais altos de dureza Knoop quando comparado ao SB. Em geral, o GC dos adesivos experimentais não foi afetado pela adição de partículas e, significantemente superior ao SB. A maioria dos adesivos experimentais mostraram menor SA e SO que o SB.Conclusões: Tanto a adição de nanopartículas quanto de micropartículas foi capaz de conferir radiopacidade aos adesivos experimentais e, a adição de carga influenciou nas propriedades testadas. De modo geral, pode-se dizer que o melhor desempenho foi para a adição de micropartículas na concentração de 30%.

The aim of this study was to evaluate the radiopacity, ultimate tensile strength (UTS), microhardness (KHN), degree of conversion (DC), water sorption (WS), solubility (SO), microtensile bond strength (μTBS) and of experimental dental adhesives with increased addition of barium-borosilicate zirconia nanoparticles or glass microparticles. Methods: Ten experimental adhesive systems with different concentrations of zirconia nanoparticles [0(EX0), 15(EX15), 25(EX25), 35(EX35) and 50%(EX50) and barium-borosilicate oxide microparticles [0(R0), 30(R30), 40(R40), 50(R50) e 60%(R60)] were formulated based on the adhesive system Ambar (FGM). The adhesive Adper Single BondTM 2 (SB, 3M ESPE) was…

Purpose: With the recent advent of many 1-step adhesive systems, clinicians’ preference have also been shifting to these systems in the clinics, although, these adhesives are being reported to produce lower bond strength compared to 2- or 3-step adhesives. Most of the 1-step adhesives are universal adhesives usable either in a self-etching mode or in a total-etching mode with a prior phosphoric acid etching step. Furthermore, bond strength of total-etch adhesives to moist dentin was found to be higher than that of dry dentin in a number of studies. The purpose of this study was to evaluate the bond performance of an universal adhesive to dentin in different etching strategies using micro-tensile bond strength (μTBS) to dentin, SEM and TEM. Methods: Two adhesive systems used were, CLEARFIL Universal Bond (CUB) and 2-step self- etch adhesive CLEARFIL Mega Bond (CMB). K-ETCHANT Syringe (Ech) was used as an etching agent. Flat dentin surfaces of human molars were exposed and polished using600 SiC paper under running water. The prepared dentin surfaces were then subdivided into the following four groups: MB (CMB in self-etch mode)- the control, NE (CUB without Ech), ED (CUB applied in dry conditions following Ech) and EW (CUB applied in wet conditions following Ech). After resin composite build-up, each specimen was sectioned after water storage at 37°C for 24 hours to obtain beams with a bonded area of 1 mm2. µTBS test was performed at a cross-head speed of 1mm/min using half of the beams from each group. Rest of the beams was tested after 6 months. The data were analyzed by one-way analysis of variance and Tukey’s test. Results: Only ED showed significantly lower µTBS after 6 months compared to its 24 hours counterpart. There was no significant difference between the 4 groups in both 24 hours and 6 months. CUB showed stable adhesion durability regardless of the strategies. Conclusion: CLEARFIL Universal Bond (CUB) showed sufficient dentin bond strength in both self-etch and total-etch strategies. In terms of bond durability, wet bonding to acid-etched dentin may be preferred over bonding to dry acid-etched dentin.

目的：臨床において 1 ステップ接着システムが広く使用されている．その多くはセルフエッチモードでも，リン酸エッチングと併用するトータルエッチモードでも使用できるユニバーサルボンドである．しかし，接着強さは従来型の接着システムと比較すると低いという報告もある．また，脱灰象牙質へのレジンの浸透には処理面を完全に乾燥しないウェットボンディングが有効という報告もある．そこで，象牙質湿潤状態がユニバーサルボンド CLEARFIL Universal Bond（CUB）のトータルエッチモードでの接着性能に与える影響を微小引張り試験，走査電子顕微鏡（SEM）および透過電子顕微鏡（TEM）で検討した．材料と方法：接着材として CUB，充填材として CLEARFIL AP-X Shade A3（AP-X），表面処理材として K-ETCHANT Syringe（Ech），接着材の比較材料として CLEARFIL Mega Bond（CMB）を用いた．28本のヒト抜去大臼歯を歯軸に対して歯科技工用トリマーにて垂直に研削し，象牙質面を露出させ耐水研磨紙#600 で研磨，水洗したものを被着面とした．歯面処理は以下 4 条件で行った．1.

Este estudo teve como objetivo a análise da interface de adesão à dentina humana, de um sistema restaurador adesivo à base de silorano. Foram confeccionadas cavidades com 4mm X 3mm X 5mm em 40 molares humanos extraídos divididos em 4 grupos aleatoriamente: Grupos SB e SB-6m: sistema adesivo (Adper™ Single Bond) + resina composta (Filtek Z250); Grupos P90 e P90-6m: sistema adesivo (P90 System Adhesive) + resina composta (Filtek P90™). Em todos os grupos, as restaurações foram inseridas em 4 incrementos oblíquos. Após a restauração, os dentes foram seccionados em fatias de 0,8mm de espessura em uma máquina de cortes com um disco de diamante. Uma fatia de cada dente foi separada aleatoriamente para análise em microscópio óptico para verificação de fendas na interface adesiva. As demais fatias foram seccionadas em palitos (0,8mm X 0,8mm) para os testes de microtração em uma máquina de ensaios universal EMIC. Os e dos grupos SB e P90 permaneceram em água deionizada em estufa a 370C por 24 horas e os grupos SB-6m e P90-6m permaneceram em água deionizada em estufa a 370C por um período de 6 meses. Os resultados de resistência de união foram submetidos à análise de variância a 2 critérios ANOVA e a presença de fendas internas foi analisada pelo testeChi-quadrado. Houve diferença estatisticamente significante na resistência de união entre os materiais (p>0,05) e tempo de armazenagem. Quanto à presença de fendas internas, foi evidenciada sua presença em todos os grupos, sem diferença etatisticamente significante entre eles (p>0,05). Conclui-se que não houve diferença entre os sistemas restauradores á base de Bis-GMA e de silorano os 2 períodos avaliados (24h e 6 meses).

This study aimed to analyse the adhesive interface to human dentin of a silorane based adhesive system. Cavities were fabricated with 4.0 mm X 3mm X 5mm in 40 extracted human molars randomly divided into 4 groups: Groups SB and SB-6m: adhesive system (Adper™ Single Bond) + composite (Filtek Z250); Groups P90 and P90- 6m: adhesive system (P90 System Adhesive) + composite (Filtek™ P90). In all groups, the restorations were inserted in 4 oblique increments. After 24 hours, teeth were sectioned buccolingually into 0.8mm slices with diamond saw. One slice of each tooth was randomly separated for microscope analysis. The other slices were sectioned into 0.8mm X0.8mm sticks for microtensile tests in a universal testing machine EMIC. Sticks of groups SB and P90 remained in deionized water at 370C C for 24 hours and sticks of groups SB-6m and P90-6m remained in deionized water at 370C for a period of six months. After storage period . The results of bond strength were analysed by Two-way ANOVA and the presence of internal gaps was analyzed by chi-square test. There was no significant difference in bond strength between materials (p> 0.05) and storage time. Regarding the presence of internal rifts, their presence was evident in all groups, with no statistically significant difference between them (p> .05).

▼ Este estudo avaliou a influência do uso do digluconato de clorexidina como inibidor de metaloproteinase na resistência adesiva e dureza da camada de adesivo e camada hibrida de uma resina composta à dentina humana, por meio de ensaio de microtração e nanoedentação. Os fatores de variação estudados foram dois sistemas adesivos com estratégias de aplicação distintas Adper Scotchbond Multi-Purpose (3M ESPE, St. Paul, MN, USA) e Clearfil SE Bond (Kuraray Co., Osaka, Japan), e ainda foram realizados tratamentos no substrato dentinário utilizando duas concentrações de digluconato de clorexidina sendo estas 2% e 0,2% e grupos controle sem tratamento com clorexidina. As unidades experimentais foram compostas por 48 molares humanos hígidos divididos aleatoriamente em 6 grupos (n=8). Nestes foram aplicados os procedimentos adesivos e realizados os tratamentos de superfície, com clorexidina, previamente aos procedimentos adesivos. Após esta etapa foram confeccionadas as restaurações com espessura de 5mm sobre as superfícies dentinárias. Após 24h de armazenamento em água destilada, os dentes restaurados foram cortados para a obtenção de corpos de prova em forma de palito, com secção transversal de aproximadamente 1mm2. De cada grupo foram selecionados aleatoriamente 5 palitos para o ensaio de dureza. O restante dos palitos viáveis de cada dente foram submetidos ao teste de microtração a uma velocidade de 0,5mm/min até que ocorresse a fratura da interface adesiva. Para o teste de nanoedentação cada um dos 5 palitos referentes aos 6 grupos estudados receberam 10 endentações, sendo 5 na camada de adesivo e 5 na camada hibrida, com distância de 10m entre si. Essas endentações foram realizadas com ultramicrôdurometro (DUH-W211S, Shimadzu Co., Tokyo, Japan). Os dados referentes aos testes de microtração dos seis grupos foram submetidos à análise de variância e teste de Tukey (p<0,05). As médias dos grupos foram: Grupo 1: Clearfil SE controle ( 28.50±0.47); Grupo 2: Adper Scotchbond controle (43.90±7.26); Grupo3: Clearfil SE/ clorexidina 2% (30.43±6.59); Grupo 4: Adper Scotchbond/ clorexidina 2% (39.21±4.69); Grupo 5: Clearfil SE 0,2%( 27.28±7.05); Grupo 6: Adper Scotchbond/ clorexidina 0,2% (35.70±6.43). Na comparação entre as médias dos grupos obteve-se que nenhum dos adesivos testados apresentou alteração na sua resistência de união com o uso do digluconato de clorexidina a 2% ou a 0,2% em análise imediata. Os grupos em que foi utilizado o adesivo Scotchbond apresentaram maiores valores de resistência de união que os grupos em que foi utilizado o sistema adesivo autocondicionante (Clearfil) independente da realização ou não do tratamento de superfície com digluconato clorexidina. Os valores de dureza da camada de adesivo não apresentaram diferenças estatisticamente significantes entre os grupos controle ou entre tratamentos, apenas o grupo com tratamento prévio Clearfil SE/Clorexidina 0,2% apresentou maior valores de dureza na camada de adesivo quando comparado ao grupo Scotchbond com a mesma concentração de clorexidina.

Resumo: O objetivo neste estudo foi avaliar a nanodureza e módulo de elasticidade da interface adesiva e sua correlação com a resistência de união do compósito à dentina após armazenamento em água por 24 horas e seis meses. Foram utilizados 80 dentes terceiros molares humanos hígidos que foram divididos aleatoriamente em quatro grupos de acordo com o sistema adesivo (Adper Scotchbond Multiuso, Adper Single Bond 2, Clearfil SE Bond e Clearfil S3 Bond) e subdividos de acordo com o período de armazenamento de 24 horas e seis meses (n=10). Dos 10 dentes, três foram selecionados para o ensaio de nanoindentação e sete para o ensaio de microtração. Os dentes foram preparados para obter superfícies planas em dentina, sobre as quais os adesivos foram aplicados e fotopolimerizados conforme as instruções dos fabricantes. Após aplicação do adesivo, a porção de resina composta foi construída de forma incremental e os dentes restaurados foram armazenados em água destilada a 37°C por 24 horas e seis meses. Os espécimes foram obtidos após o período de armazenamento em água a 37°C por 24 horas e 6 meses. Para o teste de resistência à microtração, os dentes foram seccionados para obtenção de espécimes em forma de palito com área seccional de 1 mm2. Para o teste de nanoindentação os dentes foram seccionados para obtenção de fatias com espessura de 2 mm, posteriormente incluídas em resina epóxica e a superfície exposta submetida ao desgaste com lixas abrasivas e polidas com suspensão diamantada. Foram realizadas cinco nanoindentações na camada de adesivo, na camada híbrida e na dentina, com carga de 1000 ?N em ciclo trapezoidal. A análise estatística foi realizada pelo teste de correlação de Spearman, ANOVA dois fatores (sistema adesivo e tempo de armazenamento) para todas as variáveis em estudo, seguida de comparações múltiplas de Tukey (5%). A análise de Spearman mostrou correlação significativa apenas para o módulo de elasticidade da camada de adesivo em relação resistência de união. A ANOVA não mostrou interação entre os fatores sistema adesivo e tempo de armazenamento; porém, o fator sistema adesivo isolado apresentou diferença significativa para o módulo de elasticidade e nanodureza da camada de adesivo para o adesivo Adper Single Bond 2. Os valores de resistência de união mostraram que o adesivo convencional de três passos Adper Scotchbond Multiuso e o autocondicionante de dois passos Clearfil SE Bond foram estatisticamente superiores aos adesivos convencional de dois passos Adper Single Bond 2 e autocondicionante de único passo Clearfil S3 Bond. Para os dados de nanodureza e módulo de elasticidade apenas a camada de adesivo do adesivo Adper Single Bond 2 foi estatisticamente significativa. Em…

Resumo: O objetivo neste estudo foi avaliar a influência de diferentes ciclos de temperatura na resistência da união (µTBS) e nanoinfiltração de sistemas adesivos comerciais (Convencional, autocondicionante e universal). Para este estudo foram selecionados molares humanos hígidos recém-extraídos (n=10). As raízes dos dentes foram seccionadas aproximadamente 1 mm abaixo da junção cemento-esmalte e o esmalte da superfície oclusal removido com discos diamantados de dupla face. Os dentes foram separados em três grupos: Single Bond 2 (convencional), Clearfil SE Bond (autocondicionate) e Single Bond Universal (universal). Sobre a superfície da dentina condicionada foi confeccionado um bloco de resina composta nas dimensões de 6 x 4 x 4 mm (comprimento, largura e altura, respectivamente). Em seguida, as amostras foram seccionadas em palitos (1 x 1 mm) e submetidos aos seguintes ciclos térmicos: Ciclo tradicional (5°/37°/55°C); Ciclo frio (5°/37°C); Ciclo quente (37°/55°C). As amostras foram fixadas na máquina de ensaio universal para o teste de resistência à microtração, com velocidade de 0,5 mm/min. O tipo de fratura foi analisado em microscópio eletrônico de varredura e classificadas em adesiva, mista, coesiva em resina e coesiva em dentina. Para calcular a área da camada hibrida infiltrada, imagens com aumento de 1000x das regiões central e das extremidades dos palitos foram avaliadas com software Image J (Imag J 1.42q, Wayne Rasband, National Institutes of health, USA). Os valores médios obtidos no ensaio de microtração (MPa) e nanoinfiltração (%) foram submetidos à ANOVA dois fatores e teste de Tukey (p<0,05). Os ciclos tradicional e frio proporcionaram valores similares da resistência da união no Single Bond 2, enquanto o quente o maior valor, diferindo estatisticamente dos demais grupos (p <0,05). O ciclo tradicional proporcionou menor valor de µTBS nos adesivos Clearfil SE Bond e Single Bond Universal e o quente o maior, ambos similares, enquanto o frio proporcionou valores intermediários. Quando os adesivos foram comparados em relação a cada ciclo, o tradicional proporcionou valores estatisticamente similares. Nos ciclos frio e quente o menor valor foi apresentado pelo adesivo Single Bond 2, com diferença significativa quando comparado com Clearfil SE Bond e Single Bond Universal com valores maiores e similares. Os ciclos térmicos (5/ 37/ 55° C; 5/ 37° C e 37/ 55° C) promoveram diferentes efeitos sobre a resistência da união e nanoinfiltração de sistemas adesivos comerciais. Os maiores valores de µTBS foram observados sob efeito do ciclo quente

The aim of this study was to evaluate the influence of different temperature cycles on the bond strength (?TBS) and nanoleakage…

O objetivo da presente dissertação foi avaliar a resistência da união de dentes de resina acrílica à base da prótese total removível confeccionada pela técnica convencional e CAD/CAM. No presente estudo, um teste de microtração foi realizado com uma máquina de teste universal, onde os materiais usados na construção de próteses totais removíveis foram testados. Foi avaliada a resistência à microtração de adesão de duas resinas acrílicas usadas para base de prótese, uma pré-polimerizada usada em sistemas CAD/CAM e outra por termopolimerização convencional juntamente com os dentes de resina acrílica pré-fabricados. Um total de 24 dentes molares artificiais foram preparados e divididos em 4 grupos (n = 6), de acordo com a resina utilizada e o tempo de armazenamento previo ao ensaio. A análise estatística foi realizada por meio de análise de variância de duas vias (ANOVA) com um nível de significância de 5% e um teste post hoc de Tukey. A resistência de união do acrílico com a polimerização ativada por calor aos dentes foi superior ao sistema CAD/CAM. A análise mostrou uma diferença estatisticamente significativa entre os grupos em relação ao tipo de material utilizado (resinas acrílicas convencionais polimerizadas em relação ao disco de resina acrílica CAD/CAM (p = 0.001).

The aim of this thesis was to evaluate the bond strength between artificial resin teeth and the acrylic denture base made by the conventional technique and CAD/CAM. In the present study, a microtensile bond strength test was performed with a universal test machine, where the materials used in the construction of removable complete dentures were tested. The microtensile bond strength of two PMMA acrylic resins used for the complete denture base was evaluated, one pre-polymerized used in CAD/CAM systems and another by conventional heat cure together with commercial available acrylic resin teeth. 24 artificial teeth were prepared and divided into 4 groups (n = 6). Two different acrylic resin and two storage time. Both species were evaluated immediately for their preparation and 2 groups aged and tested at 6 months. Statistical analysis was performed by a two-way ANOVA at 0.05 significance level with a post hoc Tukey test. The bond strength of heat-polymerized acrylic was higher than CAD/CAM system. The analysis showed a significant statistical difference among the groups related to the type of material used (conventional heat-polymerized acrylic resins vs CAD/CAM acrylic resins disc (p = 0.001).

Resumo: Objetivo: avaliar as propriedades físicas e a resitência de união à microtração de adesivos experimentais contendo oligômeros de tiouretano (TU) e/ou partículas de carga funcionalizadas com TU. Materiais e métodos: uma matriz orgânica base contendo 60%BisGMA/40%HEMA (peso) +0,2% DMPA 1 (fotoiniciador) + 0,5% BHT(inbidor) - (BH-controle) foi formulada; o oligômero de TU PETMP-DEMODUR (tetrafuncional) foi sintetizado e adicionado em 20%(peso) à matriz orgânica dos grupos contendo TU (BH+ 20%TU); para os grupos contendo partículas de carga, estas foram funcionalizadas com metacrilato-MF ou com tiouretano-TF e adicionadas em 10%(vol). Os grupos experimentais foram: BH; BH+10%MF; BH+10%TF; BH+20%TU+10%MF; BH+20%TU+10%TF; BH+20%TU. Os grupos foram submetidos aos testes: resistência de união à microtração (RUMT) em 24 h e 6 meses em dentina hígida (n=6); resistência à flexão (RF) por três pontos em ambiente seco (n=6) e armazenadas em água por 7 dias (n=6); Cinética de polimerização (n=3) (grau de conversão-GC e taxa máxima de polimerização-Rpmax); Sorção e Solubilidade (SR/SL) (n=3); e, Viscosidade (V)(n=3). Para a RUMT, foi adicionado 40% etanol(vol) aos grupos experimentais. Os dados foram submetidos a ANOVA um fator e teste de Tukey (p<0,05). Para a comparação entre os tempos de armazenagem das amostras da RUMT, foi aplicado o test (p<0,05). Para a RUMT (p=0,13) e SR/SL (p>0,5) e RF a seco (p>0,05), não houve diferença significativa entre os grupos. Os grupos contendo TU na matriz apresentaram os menores valores de RF (p<0,05) quando armazenados por 7 dias em água. Os grupos contendo TU na matriz apresentaram os maiores valores de GC e não houve diferença significativa entre os grupos quanto a GC-na-Rpmax. A Rpmax foi maior para o BH+20%TU+10%MF, seguido pelo BH e BH+10%TF, e os menores valores encontrados para os BH+10%MF, BH+20%TU+10%TF e BH+20%TU. Os grupos contendo TU na matriz mostraram maiores valores de viscosidade, sendo o BH+20%TU+10%TF, o qual possui TU na matriz e na funcionalização das cargas, o maior valor de viscosidade. Conclusão: Tendo em vista que a adição de TU na matriz melhorou o grau de conversão final, conclui-se que a adição de TU na matriz de adesivos experimentais apresenta-se como uma estratégia promissora

The aim of the study was to evaluate the effect of adding thio-urethane oligomers (TU) on physical properties and the microtensile bond strength of experimental adhesive and/or thio-urethane functionalized fillers.

This study aims to test different adhesive protocols, as well as influence of chemical changes of Single Bond Universal to verify improvement in bond strength and stability of the hybrid layer. One hundred and forty-four teeth was obtained through the Bank of Human permanent teeth of UFSM and randomly assigned to each group, divided by the type of application protocol (control, Chlorhexidine, Warm Air, Double adhesive application, Photoactivation for 40 seconds and "All in One"), the type of adhesive (Single Bond Universal and Single Bond Universal modified) and storage time (24 hours and 06 months). To test the effects of the chemical change versus protocol was used a single multi-mode ethanol-based adhesive (Single Bond Universal) to isolate the chemical composition factor. Changes in chemical composition were held by incorporating the adhesive of a acrylamide of pharmaceutical use. The addition of the polymer will occur in a concentration of 1ml/0,05ml the adhesive to generate a different versions to be tested. To analyze the differences between the two adhesives, ultimate bond strength analyzes was made to compare properties of the universal single bond with the universal single bond modified. To verify differences in the hybrid layer and the bond strength between the adhesive and the different application protocols, microtensile tests was done. The conceptual hypothesis of this study is that altered viscosity and different application protocols will improve adhesive properties and long-term bond strength. The null hypothesis is that changes in the protocol and viscosity of the adhesive do not result in significant improvements in outcomes studied. The results observed in the two articles showed an increase in dentin bond strength when an adhesive with addition of acrylamide was used, as well as an increase in its intrinsic resistance verified by ultimate tests in both articles. Among the protocols, the group "all-in-One" obtained the best results but without statistical difference compared to Chlorhexidine, Warm air and Double Application. The Control group presented the worst result however was not statistically worse than the 40s Group. The addition of acrylamide in a universal ethanol based adhesive increased its intrinsic resistance as well as the dentin bond strength. Some changes in the adhesive´s protocol of a universal adhesive also increased the dentin bond strength.

Este trabalho tem o propósito de testar diferentes protocolos adesivos, bem como influência da alteração de composição do sistema adesivo universal Single Bond Universal com o intuito de verificar o efeito obtido na resistência de união e estabilidade da camada híbrida. Cento e quarenta e quatro dentes foram obtidos através do Banco de dentes permanentes Humanos da UFSM e distribuídos aleatoriamente para cada grupo, divididos de acordo com o protocolo de aplicação (Controle, Clorexidina, Ar Quente, Dupla aplicação do adesivo, Fotoativação por 40 segundos e “All in…

▼ Le collage direct est maintenant utilisé par un nombre croissant d'applications en microélectronique (Elaboration de SOI, technologie imager Back Side Illumination, technologies 3D...). C'est une technique d'assemblage permettant de coller deux surfaces sans apport de matière adhésive. Principalement utilisée pour le collage de wafers, elle vient en complément de techniques telles que l'épitaxie ou le dépôt de couches minces. Ce collage s'effectue sous certaines conditions : il faut que les surfaces soient suffisamment propres, planes et lisses pour qu'il y ait une adhésion spontanée à température et pression ambiante. Enfin, un traitement thermique est appliqué pour augmenter l'énergie d'adhérence. Pendant le processus de fabrication, il peut apparaître des défauts de collage qui sont essentiellement dus à un piégeage de particules. Ces défauts se présentent sous la forme de bulles d'air. Finalement, les défauts de collage et l'énergie de collage sont les deux caractéristiques à partir desquelles est déduite une qualité de collage.Aujourd'hui, la technique utilisée pour la mesure d'énergie de collage est le clivage au coin. C'est une technique qui consiste dans un premier temps à séparer partiellement deux wafers par une lame, et dans un second temps, à calculer l'énergie de collage à partir d'une équation comportementale qui intègre la longueur de décollement. Mis à part le fait qu'elle permette la mesure d'énergie seulement sur quelques points, il se trouve que c'est une technique destructive. Un contrôle non destructif serait très intéressant pour l'industrie microélectronique et spécialement pour les lignes d'inspection. De plus, les procédés de fabrication microélectronique n'étant pas uniforme, avoir la possibilité d'obtenir une cartographie d'énergie de collage serait un atout majeur. A ce jour, aucune technique respectant ces deux exigences n'est connue. L'objectif de cette étude est d'utiliser la microscopie acoustique pour mesurer l'énergie de collage.Dans cette étude, un modèle inspiré de la "méthode des matrices hybrides" a été développé afin de modéliser des collages de différentes qualités. Le résultat de la modélisation montrera que le coefficient de réflexion acoustique de la structure collée est influencé par la qualité d'interface. En se plaçant dans des conditions précises, une méthode expérimentale est alors réalisée pour la mesure de la qualité d'interface. En parallèle, des wafers de Silicium réalisés par collage direct ont été spécialement conçus pour valider la méthode. Sur ce principe, des cartographies bidimensionnelles d'énergie de collage sont réalisées.Dans un second temps, la technique est améliorée afin d'augmenter la résolution latérale. Pour cela, un transducteur ayant une lentille est utilisé pour focalisé les ondes ultrasonores en points du collage. Une étude théorique est tout d'abord menée en utilisant le modèle du "spectre angulaire" afin de simuler la diffraction par la lentille. Enfin, des cartographies expérimentales confirmeront la faisabilité de mesures d'énergie de collage… Advisors/Committee Members: Le Clézio, Emmanuel (thesis director), Despaux, Gilles (thesis director).

L’électronisation de l’industrie a mené à l’augmentation de la pollution électromagnétique pouvant être néfaste pour les systèmes électroniques sensibles et les êtres vivants. L’un des moyens pour limiter la propagation des champs électromagnétiques est l’utilisation d’un blindage. L’étude s’est ainsi focalisée sur l’élaboration à froid d’un composite bimétallique pour le blindage magnétique. Le composite étudié allie les propriétés physiques de l’aluminium et de l’acier via le trilame Al8011/AcierDC01/Al8011. Le trilame est élaboré par colaminage à température ambiante. Il s’est avéré que la qualité de l’adhérence des interfaces Al/Acier et l’architecture du trilame dépendent fortement des paramètres du colaminage. Une préparation minutieuse des tôles et de leurs surfaces concomitantes se révèle être tout aussi importante que le colaminage en lui-même. De plus, au cours du colaminage, la tôle d’acier s’est montrée sensible à des instabilités plastiques qui amènent par la suite à sa striction et à sa fragmentation. Ces instabilités plastiques favorisent l’adhérence grâce à des soudages Al/Al mais n’en sont pas un prérequis. Au niveau de l’efficacité de blindage, le trilame s’est révélé être particulièrement intéressant puisque, grâce à sa composition et à sa structuration, il est capable d’atténuer aussi bien les champs magnétiques basses fréquences (< 1 kHz) que les champs magnétiques de plus hautes fréquences (> 1 kHz). Dans une étude à iso-masse, le trilame a présenté une meilleure efficacité de blindage que les tôles d’Al, de Cu et d’acier. Cependant, la fragmentation de l’acier dans le trilame s’est révélée être néfaste pour le blindage magnétique, nécessitant de faire alors un compromis entre tenue mécanique et efficacité de blindage.

The growth of electronic devices has led to an increase in electromagnetic pollution that can be harmful to sensitive electronic systems and living beings. One of the means of limiting the propagation of electromagnetic fields is the use of shielding. Then, the study focused on the elaboration of a bimetallic composite for magnetic shielding. The studied composite combines the physical properties of aluminum and steel via the Al8011/SteelDC01/Al8011 trilayer. The trilayer is produced by cold roll bonding (CRB). It has been found that the adherence quality of the Al/Steel interfaces and the architecture of the composite heavily depend on the CRB parameters. Careful preparation of the sheet and their concomitant surfaces is just as important as CRB itself. Furthermore, during CRB, the steel sheet was sensitive to plastic instabilities which subsequently led to its necking and fragmentation. These plastic instabilities promote adherence through Al/Al welds but are not a prerequisite. In terms of shielding effectiveness, the bimetallic composite has proved to be particularly interesting. Thanks to its composition and its structuring, it can attenuate both low (< 1 kHz) and high frequency (> 1 kHz) magnetic fields. In an iso-mass study, the composite showed a higher shielding…

▼ Strong underwater bonds between polycarbonate sheet and various other substrates were achieved using ethyl 2-cyanoacrylate gel cured with an anionic photoinitiator (dibenzoylferrocene). The gel reacts quickly with water on contact and forms a protective polyethyl cyanoacrylate (PECA) skin. This provides a diffusion barrier that protects the inner monomer from further reaction with or polymerisation by water (hydroxide ions). The PECA skin is, however, permeable to water and the inner monomer slowly reacts as water diffuses through the PECA skin. The application procedure for this adhesive is critical because of the fast reaction with water. The adhesive should be applied at the centre of the bond area in such a way as to cover the smallest exposed surface area and that it should not be spread out over the entire surface area. The PECA skin will rupture when the substrates are pressed together, exposing unreacted monomer to the fresh new surface between the two substrates. The adhesive displaces water as it propagates towards the joint edges. In this way it is able to form a strong underwater bond. Without a photoinitiator, ethyl cyanoacrylate adhesives will form strong bonds to smooth underwater surfaces. The addition of a photoinitiator (dibenzoylferrocene), however, increases the rate at which the bond strength develops. Photo differential scanning calorimetric (photo-DSC) analysis was used to determine the optimum photoinitiator concentration. A concentration of between 0.3% (m/m) and 0.1% (m/m) was found to be optimum for adhesive films between 0.5 and 1.2 mm thick. Epoxy-based underwater adhesives have the disadvantage that the cure rate is very slow at low water temperatures. In contrast, the current system features a negative temperature dependence. Therefore, the curing rate is faster at lower water temperatures, making it highly suitable for very cold environmental conditions. The underwater bonding properties of cyanoacrylate adhesive were measured on a wide range of metallic and non-metallic materials. Bond strengths ranged from 1 to 5 MPa respectively. Bond strength (0.2 mm film thickness) develops in a very short time (less than a minute) using a 5 mW/cm2 blue LED light source as trigger for the photo initiator. Water temperatures between 1.5 and 40 °C did not influence the ultimate bond strength achieved following 50 seconds of illumination. The reduction in bond strength due to the ethyl cyanoacrylates reacting with water was measured in artificial sea water and potable water. A 20% reduction in bond strength was found after 10 minutes of water exposure. The underwater bond should therefore be made as soon as possible following exposure to water. Bond ageing studies on both steel and polycarbonate showed an initial decrease in bond strength (during the first 50 hours); thereafter the bond strength stabilises.
