▼ Evaluation of the facial soft tissue profile is an essential part of the orthodontic treatment planning process. This retrospective study investigates longitudinal soft tissue changes in orthodontically untreated subjects with Class II division 1 malocclusions throughout the circumpubertal growth peak period. Lateral cephalometric radiographs of two groups of untreated males and females with Class II division 1 malocclusions were evaluated for soft tissue profile changes from the late pre-pubertal peak period (T1) to the early post-pubertal peak period (T2), where T1 and T2 correspond to CS3 and CS5 stages respectively, from the improved version of the Cervical Vertebral Maturation (CVM) method devised by Baccetti et al. Four commonly used linear measurements and five angular measurements were evaluated and compared for both groups. Differences between measurements for females at T1 and T2, between males at T1 and T2, between males and females at each time point, between absolute changes in males and females during the circumpubertal growth peak period, and between Class II subjects and a Class I control group at each time point, were tested for statistically significant differences. Results showed that males have a longer circumpubertal growth peak period that starts at a later age. Females with Class II division 1 malocclusions have a more convex soft tissue profile compared to males. A notable increase in total soft tissue profile convexity, and increased retrusiveness of upper and lower lips relative to E plane occurs subsequent to the pubertal growth peak in males and females. It is largely attributed to forward growth of the nose. Compared to Class I controls, Class II subjects have more convex profiles.

▼ Inadequate oral hygiene practices lead to gingivitis, periodontitis, and tooth decay. There are numerous oral care products on the market which aim to assist the general public to improve plaque removal efficacy at home, such as disclosing tablets, mouth rinses, and toothpastes containing antimicrobials. Plaque-A-Way (TJA Health, Joliet, IL) is a newly developed dentifrice which incorporates a disclosing agent into the formulation. The purpose of this study was to compare the plaque removal efficacy of Plaque-A-Way to that of a placebo toothpaste.
There are several methods for measuring plaque in the oral cavity. These include conventional plaque indices, which measure the presence, absence, or amount of plaque in designated tooth locations; planimetry, which maps the outline of plaque and calculates the percentage of coverage; quantitative light-induced fluorescence (QLF), which illuminates the oral cavity with ultraviolet light that results in red auto-fluorescence of plaque deposits; and digital plaque imaging analysis (DPIA), which discloses plaque with fluorescein causing deposits to glow yellow-green when exposed to ultraviolet light followed by a computerized photo analysis.
Thirty-five subjects completed this study. After a period of refraining from oral hygiene, subjects were asked to brush their teeth with either the test toothpaste (Plaque-A-Way) or a placebo toothpaste at two separate appointments. No special brushing instructions were given to the subjects. A rinse sequence was completed using fluorescein to disclose any remaining plaque after brushing. An
intraoral photo was captured and analyzed for percentage plaque coverage using custom made DPIA software.
The changes of plaque percentages between appointments for the control and test groups were calculated and there were no statistically significant differences found between the two. This suggests that the use of Plaque-A-Way did not result in a significant amount of plaque removal compared to the placebo with the testing protocol used. This may have been due to several limitations to this study including: non-specific brushing instructions, small sample size, inconsistent lighting parameters, and investigator subjectivity during photo processing. Despite inconclusive results obtained from the present study, the test toothpaste (Plaque-A-Way) demonstrates potential as a valuable over-the counter (OTC) oral hygiene aid for the general public.

▼ Background:
Ineffective oral hygiene may cause damage to hard and soft tissues, especially in orthodontic patients whose fixed appliances trap plaque close to tooth surfaces. Products able to reveal remaining plaque after mechanical removal have the potential to increase patients’ awareness and encourage more thorough homecare, and therefore reduce oral disease. However, no products with the combined properties of dentifrice and plaque-indicator were previously available on the market. The purpose of this study was to test a novel product (PlaqueHD) to determine whether it promotes more effective plaque removal than conventional dentifrices.
Methods:
Thirty-one participants were randomized and divided into groups. Control group participants used only control toothpaste at two visits; experimental group participants had a baseline visit with control toothpaste and a second visit with experimental toothpaste. The control and the experimental toothpaste had similar chemical compositions apart from the presence of plaque-indicating dye in the experimental toothpaste.
Prior to both visits there was a brief period of hygiene cessation. At the initial visit for both groups, subjects were asked to brush using the control toothpaste, then rinse with a fluorescein solution, then take intraoral photographs. Photographs were taken using an ultraviolet digital plaque imaging assessment which detects plaque-bound fluorescein on tooth surfaces. The second visit followed identical protocols, however the control group continued to brush with the control toothpaste while the experimental group received PlaqueHD and were asked to “brush away any green staining” they may see. Images from the two time points were compared using custom software to calculate a percentage change of remaining plaque. Statistics were performed to determine mean plaque reduction.
Results:
Results show that participants using the experimental product had significantly less plaque remaining between visits (51.3% plaque reduction, p=0.015) than participants using the control dentifrice only (22.5% plaque reduction, p=0.189).
Conclusions:
The results of this study demonstrated that plaque removal was significantly more effective when using toothpaste containing plaque-indicating dye. Patient hygiene can significantly improve, especially for those whose fixed orthodontic appliances are an inherent cleaning obstacle that can be more easily overcome when using a visual hygiene indicator.

▼ Hypothesis: We hypothesize that there is no statistical significant mean difference nor association of the vertical location and sagittal dimension between the minimum cross sectional area (MCSA) of airway in CBCT scans and the minimum sagittal linear dimension (MSLD) of airway in 2D reconstructed lateral cephalograms (RLC) in an orthodontic population. Objective: To investigate the mean difference and association of the vertical location and sagittal dimension between MCSA of airway in CBCT scans and MSLD of airway in 2D RLC. Methods: CBCT-scans of 91 patients, grouped into three age groups (≤20, 21-40 and >40 years), were utilized to perform a 3D assessment of the upper airway and to reconstruct lateral and postero- anterior cephalograms (PAC). Airway volume, MCSA, vertical level and sagittal dimension of MCSA in CBCT and MSLD of airway in 2D RLC as well as linear transverse measurements in 2D reconstructed PAC were computed and analyzed. Results: In all age groups, there was no significant mean difference between the vertical location of MSCA in CBCT and MSLD in 2D RLC. However, there was a significant mean difference between the sagittal dimension of MCSA in CBCT and MSLD in 2D RLC (p< 0.05). In all age groups, correlation tests showed moderate-strong significant correlation between the vertical location of MSCA in CBCT and MSLD in 2D RLC (0.611 ≥ r ≤ 0.727). Pearson correlation test showed strong significant correlation between the sagittal dimension of MSCA in CBCT and MSLD in 2D RLC (r = 0.873) in the youngest age group. Conclusion: Two dimensional reconstructed lateral cephalograms may be used as screening tool to identify the vertical location of minimum sagittal measurement of oropharyngeal airway. However, comprehensive assessment of airway characteristics is better achieved with CBCT-based 3D evaluation. Funding: UIC College of Dentistry, Department of Orthodontics.

▼ Introduction: Gingival crevicular fluid (GCF) has been widely investigated as a potential source of biomarkers for an individual’s oral and general health information. MicroRNAs (miRNAs) are non-coding RNAs that are involved in post-transcriptional gene regulation. In this study, we investigated potentials of certain miRNAs in GCF as biomarkers for detection of periodontal remodeling during OTM. The aim of the study was to confirm the presence of secretory miRNAs in GCF and investigate temporal expression profiles of specific secretory miRNAs during the course of orthodontic tooth movement.
Methods: A total of 70 subjects were recruited in the study from the patients receiving treatment at the
University of
Illinois at Chicago’s orthodontic clinic. The inclusion criteria included subjects requiring extraction of maxillary first premolars as part of their comprehensive treatment with edgewise fixed appliances. Ultimately 11 GCF samples were collected from
healthy subjects between the ages 10 and 18 (mean 14.5 years old), who maintained excellent oral hygiene throughout the study. GCF was collected using absorbent Periopaper strip at six timepoints.
T0: prior to bonding the fixed orthodontic appliances
T1: on the day of canine retraction
T2: 60 minutes after activating the power chain
T3: 1 day after the canine retraction visit
T4: 7 days after the canine retraction visit
T5: between 5 weeks after initiation of canine retraction
Human Let7d, g and i were used for normalization of secretory miRNA levels in GCF. Wilcoxon Sign Rank and Kruskal-Wallis and Mann-Whitney U statistical analyses were used in this study
Results: In all studied miRNAs, the change in expression of miRNA from T1 to T5 showed statistical significance consistently (p-value ranging from 0.005 to 0.047). Changes between T1 and T2 were only observed in miRNA-29b. Changes between T1 and T4 were observed in both miRNA-101 and miRNA-29b. Analyzing all the time points together, Kruskal-Wallis test showed no statistical significant difference between miRNA-29a, miRNA-29b and miRNA-29c, (p>0.05, p-value ranging from 0.201 to 0.802) indicating the similarity in profile change of miRNA-29 family.
Conclusions: We concluded that secretory miRNAs exist in GCF and the expression levels of miRNA-29 family change during orthodontic tooth movement.

ABSTRACT
Hypothesis: There is no difference in tensile bond strength values of metal orthodontic attachments to feldspathic porcelain and zirconia with various bonding protocols.
Objectives: To evaluate the tensile bond strength (TBS) of metal orthodontic attachments to sandblasted feldspathic porcelain and zirconia with various protocols.
Methods: Thirty-six (36) feldspathic porcelain and 36 zirconia disc samples were prepared, ultrasonically cleansed, glazed, embedded in acrylic blocks, and sandblasted. Each material was divided into three groups according to one or more of the following surface treatments: hydrofluoric acid 4% (HF), Porcelain conditioner silane primer (Reliance Orthodontic Products, Itasca, IL) (trimethoxysilyl-propyl-2-methyl-2-propeonic acid and acetone), Reliance Assure® (RA®) (Reliance Orthodontic Products, Itasca, IL) primer (biphenyl dimethacrylate, hydroxymethyl acrylate), Reliance Assure plus® (RA® plus) (Reliance Orthodontic Products, Itasca, IL) primer (bisphenol A-glycidyl methacrylate and ethanol), Z Prime™ plus (Bisco, Schaumburg, IL) zirconia primer (biphenyl dimethacrylate, 10-methacryloyloxydecyl dihydrogen phosphate, and ethanol). A round traction hook (TP Orthodontics, La Porte, IN) was bonded to each sample using Pad Lock™ light cure composite (Reliance Orthodontic Products, Itasca, IL) cured for 20 seconds. Static tensile bond strength tests were performed in a universal testing machine (Model 1125, Instron Corp, Canton, MA) at 1mm/min cross-head speed. The adhesive remnant index (ARI) scoring was done in an optical microscope. Data obtained (MPa) were analyzed using ANOVA. ARI scores were analyzed using crosstabulation and Pearson chi-square test. Significance level was set at 0.05.
Results: No statistically significant mean difference in the TBS was found among the different bonding protocols for feldspathic and zirconia: (Mean ± S.D.; p-value) = (4.57±0.70; 0.369) and (5.29±0.55; 0.944) respectively. ARI scores for feldspathic was not statistically significant; p-value=0.569, for zirconia the results indicated that RA® plus, Z Prime™ plus and silane are significantly different; p-value=0.026. Silanization of zirconia samples resulted in more than 50% of the adhesive being left at the debonded site.
Conclusion: Silanization following sandblasting resulted in tensile bond strengths comparable to other bonding protocols for feldspathic and zirconia surfaces.

▼ Hypothesis: Effects of unilateral maxillary premolar extraction treatment on dental arch form and midline deviation do not differ significantly from bilateral maxillary premolar extraction treatment. Distances of corresponding points between right and left sides of the dental arch are approximately the same within each group. Objective: A retrospective study evaluating post-treatment maxillary arch forms and midlines for asymmetry in Class II subdivisions treated with unilateral and bilateral maxillary premolar extractions. Methods: Using GeoMagicTM and MATLABTM softwares, best fit curves expressed as quadratic polynomials were generated from post-treatment digital models of fifteen Class II subdivisions treated with unilateral and twenty with bilateral maxillary premolar extractions. Transverse and sagittal measurements were recorded to analyze asymmetry in arch form. Midline deviation relative to the mid-palatal raphe was calculated. Dental models were superimposed on constructed reference planes to generate average post-treatment arches. Statistical comparisons were performed with significance level set at p ≤ 0.05. Results: Within the unilateral extraction group, anterior, anterior-middle and middle segments showed significant differences in arch form between right and left sides transversely, and all segments of the arch aside from the posterior segment in the sagittal dimension. Bilateral premolar extraction treatment did not show significant differences in arch form between right and left sides in either dimension. Significant differences were found between the groups in anterior and anterior-middle segments of the arch transversely, and in the middle and middle-posterior segments sagittally. A significant difference in midline deviation relative to the mid-sagittal plane was observed between the groups. Superimposed average arches showed similar results. Conclusions: Unilateral maxillary extraction treatment generally results in a narrower and more posteriorly displaced arch form on the extraction side, with a deviated maxillary midline from the mid-palatal raphe towards the extraction side of the arch.

▼ INTRODUCTION: One of the most common side effects of orthodontic treatment is root resorption, a reactive process in which the length of the dental roots become progressively shortened during treatment. A phenomenon of developmentally-short dental roots, known as Short Root Anomaly (SRA) has been observed in many orthodontic patients of Hispanic descent in the UIC Orthodontic clinic. Studies have reported a predisposition to root resorption in Caucasian patients with developmentally short roots. While the presentation of SRA in Hispanic patients has been described previously, it is not known if this population is predisposed to increased orthodontic root resorption.
METHODS: Maxillary and mandibular central and lateral incisors and second premolars of 40 Hispanic patients with SRA (19 male, 21 female) and 40 Caucasian patients (19 male, 21 female), matched for age and extractions, were evaluated for root resorption following comprehensive orthodontic treatment. Panoramic radiographs were measured digitally and relative root length was calculated before and after orthodontic treatment.
RESULTS: The results from paired sample t-tests demonstrate that, while there was statistically significant root resorption in the control group following comprehensive orthodontic treatment, orthodontic root resorption was not significant in the Hispanic group (P> 0.05). When genders were separated, Hispanic females did experience a mild degree of root resorption in the upper incisors. Caucasian females experienced greater root resorption than Caucasian males.
CONCLUSION: These data indicate that Hispanic SRA patients may be safely treated with orthodontics and could be at no more risk of root resorption than Caucasian patients with normal initial root length. Although more studies are needed, these findings can be used in making educated treatment decisions regarding this specialized population of orthodontic patients. To the authors’ knowledge, this is the first study to evaluate the response of Hispanic patients with SRA to orthodontic treatment.

▼ Hypothesis: In the long term, Vivera® and Essix® ACE are not significantly different in transmittance, surface roughness, and flexural modulus among 7 cleaning methods. Objective: Clear retainers have increased in popularity due to their esthetic nature. However, few studies have focused on long-term maintenance of these retainers. This study evaluated the long-term effects of 7 different cleaning methods on light transmittance, flexural modulus, and surface roughness of Vivera® material. Methods: Vivera® retainer (Align® Technology) specimens (n=10,2x0.5x0.04in) were exposed to 7 different cleaning methods: Invisalign® cleaning crystals, Polident®, Listerine®, 2.5% vinegar, 0.6% sodium hypochlorite, 3% hydrogen peroxide, and toothbrushing with distilled water twice a week for 6 months. Before treatment and after 6 months, light transmittance, flexural modulus, and surface roughness of specimens were quantified. Qualitative assessment of random specimens from each method was performed at 6 months using a scanning electron microscope. Mean difference comparisons were done using the independent student t-test and ANOVA (P<0.05). Results: A decrease in transmittance of specimens was found with all cleaning methods compared to baseline, with toothbrushing causing the greatest decrease for Vivera® and Listerine® causing the greatest decrease for ACE. Surface roughness was unaffected by the cleaning methods except NaOCl eliciting a difference in Vivera and Listerine with ACE. Quantitative analysis with SEM however showed negligible difference. Vinegar and toothbrushing showed an increase in flexural modulus in Vivera®, however when compared to each other, showed no difference. All methods increased modulus for ACE except for Invisalign Crystals. Hydrogen peroxide caused the greatest decrease in flexibility of ACE. Conclusions: Over the long-term there is a gradual decrease in transmittance of clear retainers with certain solutions creating less translucency. Surface roughness and flexibility are generally unaffected in the long term but may be affected by oxiders. Funding: Align® Technology

▼ Hypothesis: We first hypothesize that there is diversity of teaching methods and resources available for residents in periodontics programs through North America. Secondly, we want to discover the top articles listed by different periodontics program in order to unify of content for teaching in North America.
Objective: To provide information regarding teaching methods and contents in order to prepare residents for ABP in every program.
Methods: Part one: The initial survey was sent to the 63 Periodontics Department Program Directors of American and Canadian schools. Included was an 8-page questionnaire and blank flash drive to be used in transmitting detailed literature review subjects and articles. The responding schools were then categorized into five different regions: 1- East, 2- West, 3- Midwest, 4- South, 5- Canada. Reponses were given a numeric code with the identification of the school linked to the code stored separately to ensure program confidentiality.
Part two: The original excel spread sheet was composed of 6 columns in order of article title, school number, region, institution’s choice of topics, and classification based on classic/ current/ or implant literature. In order to unify the referencing layout for all articles, the American Medical Association (AMA) format was used.
Results: The results show no significant differences between selected regions with regards to teaching methodology of classical, contemporary, implant literature review courses. Formulated cross tabulation reveals different frequencies in individual responses. However, it clearly reveals significant differences in the contents of the courses.
Conclusions: This research emphasizes the need to unify and comprehensively set forth a protocol in selecting the contents of literature reviewed for every resident at every level of their education. In addition, providing consolidated and comprehensive course contents can help every resident in national exam preparations.

▼ Introduction: The purpose of this randomized controlled trial was to evaluate the effect of AcceleDent Aura device on maxillary and mandibular arch alignment and pain during orthodontic treatment with SureSmile. Methods: Seventy-one subjects undergoing non-extraction comprehensive orthodontic treatment with SureSmile were randomly assigned into experimental group that used AcceleDent device and control group that used no additional device. Little’s irregularity index was used to evaluate maxillary and mandibular anterior teeth alignment at four time points – initial, 3 months, 6 months, and 12 month or end of treatment. Pain intensity and compliance with AcceleDent were recorded. Results: Out of total initial sample, data from sixty-one subjects were analyzed. There were no statistical significant differences in the initial upper and lower arches irregularity indices between the two groups, p-value > 0.05. At all follow up time points, the mean irregularity indices were consecutively smaller for both upper and lower arches. Within each group these differences were statistically significant with p-value <0.001. However, the mean differences in irregularity index were not statistically significant between the experimental and control groups at any time points. There was no difference in pain levels between the two groups during initial 3 months of the treatment for the 3 days evaluated; however, pain was significantly lower in the experimental group from the third month until the end of the treatment, p-value = 0.006. Average compliance with AcceleDent use was 78%. Conclusion: The AcceleDent Aura device had no effect on arch alignment. Likewise, device did not have any effect on pain level during initial three months. After 3 months until the end of the treatment, AcceleDent group had significantly less pain compared to the control group during the initial 3 days post-adjustment appointments.

▼ Since its introduction to the orthodontic field in the 1970s, Nickel-Titanium (Ni-Ti) has become the predominant material for the initial leveling and aligning phase of orthodontic treatment. The alloy’s ability to reversibly transform between two lattice structures determines the material’s properties, and thus, its clinical practicality. This transformation occurs as a result of a change in ambient temperature or in the area of a locally applied stress. The range of temperatures over which Ni-Ti transforms from one lattice structure to the other is called its transformation temperature range (TTR). Consequently, TTR is largely responsible for the clinical application of Ni-Ti.
The aim of this study was to examine how varying levels of strain affected the transformation temperature of two brands of Ni-Ti archwires using the bend and free recovery (BFR) method. Strain was altered in this study by two different techniques. The first technique was by varying the diameter of the mandrel over which the Ni-Ti wire was bent, where a smaller diameter mandrel results in a higher strain placed on the archwire. The second technique of varying wire strain was by bending two different dimensions of wires over the same size mandrel, where a larger wire results in a higher strain placed on the archwire. Additionally, the manufacturer-reported transformation temperatures of the wires were compared to the transformation temperatures obtained in this study.
The results demonstrated that TTR values are affected by strain. Increased strain resulted in increased transformation temperature values and decreased range. While this was the trend for increased strain whether by decreasing mandrel diameter or increasing wire size, one company did not have similar results when strain was increased by increasing wire dimension. This may have been a result of only testing two production lots. Additionally, there was a statistically significant difference between the obtained values in this study and those reported by the manufacturers.

▼ The objective of the this study was to compare accuracy and reliability of the American Board of Orthodontics Discrepancy Index obtained manually on plaster casts (the gold standard) with scores obtained using their digital models in OrthoCad software and Motion View’s Ortho Insight 3D software. Plaster models were obtained from 45 previous patients with varying degrees of malocclusion. Measurements were completed manually with a periodontal probe as necessary. The same casts were scanned and analyzed using Ortho Insight 3D (Motion View Software, Hixson, TN). Alginate impressions were made of the original plaster casts and sent to OrthoCad (Cadent, Carlstadt, NJ) for digital model fabrication and analysis. Total DI score and its target disorders were computed manually on plaster casts and digitally using the respective software. Intra-rater and inter-rater reliability was assessed for 15 subjects using Spearman’s Rho correlation test. Accuracy DI scores and its target disorders were assessed for all 45 subjects using Wilcoxon signed ranks test to determine differences in digital calculation compared to manual calculation. Intra-rater and inter-rater reliability was high for total DI score and most target disorders (r>0.8). No significant difference was found between total DI score when measured with OrthoCad compared to manual calculation. Total DI score calculated by Ortho Insight 3D was found to be significantly larger than manual calculation by 2.71 points.

▼ Palatal rugae, also known as plicae palatinae transversae and rugae palatine, are situated in the anterior third of the hard mucosal palate in the roof of the mouth. While there is literature suggesting that the palatal rugae could be used for human identification, most of these studies use two-dimensional (2D) approach. Scanning three-dimensional (3D) technology could facilitate the computerized matching of palatal rugae patterns in a manner comparable to the current gold standard for assessing fingerprints.
The aims of this study were to evaluate palatal rugae patterns using three-dimensional (3D) digital models; to compare the most clinically relevant digital model conversion techniques for identification of the palatal rugae; to develop a protocol for overlay registration; to determine changes in palatal rugae individual patterns through time and following orthodontic treatment; and to investigate the efficiency and accuracy of 3D matching processes between different individuals’ patterns.
Initially, the palatal rugae area for each digital impression was isolated as a separate 3D image, and two impressions were registered by manual alignment followed by global registration. Five cross sections in the anteroposterior dimension and four cross sections in the transverse dimension were computed which generated eighteen 2D variables. In addition, thirteen 3D variables were defined using the annotation function in the software: the posterior point of incisive papilla (IP), and the most medial and lateral end points of the palatal rugae (R1MR, R1ML, R1LR, R1LL, R2MR, R2ML, R2LR, R2LL, R3MR, R3ML, R3LR, and R3LL). The deviation magnitude for each variable was statistically analyzed in this study.
Five different data sets with the same thirty one different landmarks were evaluated in this study. The results demonstrated that two-dimensional (2D) images and linear measurements in anteroposterior and transverse dimension were not sufficient for comparing different digital model conversion techniques using the palatal rugae. 3D digital models proved to be a highly effective tool in evaluating different palatal rugae patterns. The 3D landmarks showed no statistically mean differences over time and as a result of orthodontic treatment. No statistically mean difference was found between different digital model conversion techniques, between OrthoCAD™ and Ortho Insight 3D™ and between Ortho Insight 3D™ and the iTero® scans, when using twelve 3D palatal rugae landmarks for comparison. Although all twelve palatal 3D landmarks could be used for human identification over time, certain landmarks showed more significant impact on the matching process and were arranged by strength and importance.
In this study, a three-dimensional (3D) approach was developed and utilized for human verification and identification using the palatal rugae pattern. Proposed values for 3D palatal landmarks were introduced that could be useful in biometrics and forensic odontology for human verification or identification in cases of traffic accidents,…

▼ Background: Decalcification of enamel is a major concern for orthodontists. The patient’s diet plays a major role in the demineralization process. In recent years, soft drink consumption in developing countries has increased dramatically. It is the orthodontist’s responsibility to minimalize white spot lesions during orthodontic treatment. Preventive measures include oral hygiene and fluoride treatments. Othodontist applied primer is another preventative measure that does not rely on patient compliance. Newer highly filled and flouride relesaing primers such as Opal Seal are now available. The effectiveness of these primers in preventing demineralization have not been extensively studied using newer evaluation methods.
Methods: Bovine incisors were prepared and sectioned into blocks of enamel. Quantitiative Light-Induced Fluorescence (QLF) images were taken at baseline. Samples were randomly assigned into the control group (exposed enamel), Transbond XT group, or Opal Seal Group. Aging was simulated by subjecting the samples to 500 cycles in a thermocycling apparatus. Following thermocycling, the samples were pH cycled. During the acidic challenge, samples were exposed to a test beverage twice a day for 25 minutes. Test beverages included water, Diet Mountain Dew ,and Coke Classic. Samples underwent a total of 7 days of cycling. Final QLF images were taken to evaluate the demineralization of enamel.
Results: A statistically significant interaction was found between the surface protected groups and the test beverage groups (p<0.05). A statistically signficant difference (p<0.05) was found between the Coke Classic group, Diet Mountain Dew (DMD), and Water treated groups. There was also a statistically significant difference between the Opal Seal, Transbond XT, and control groups (p<0.05).
Conclusions: Coke Classic was the most aggressive in eroding through the sealant layer resulting in demineralization. The most protective effect was seen in the Opal Seal group with statistically significant prevention of demineraization versus control and Trasbond XT. Transbond XT showed statistically significant protection vesus control in the Coke Classic treated group only. These data suggests that enamel surface protection using a highly filled and flouride releasing and recharging primer may be a beneficial technique during orthodontic treatment to prevent enamel decalcification.

▼ Objective: The study objective was to investigate what type of esthetic orthodontic wire coating provides less frictional resistance when used with ceramic polycrystalline brackets compared to each other and to non-coated stainless steel archwire. Consistency of wire sizes with dimensions reported by manufacturers, and effect of stainless steel core diameter on frictional characteristics were also investigated. Methods: Canine retraction model was constructed allowing to simulate forces and conditions existing on the bracket/wire interface during orthodontic tooth movement. Static and kinetic resistance to sliding of three coated archwires from different manufacturers was measured using Instron testing machine and compared to each other and non-coated stainless steel control wire. Dimensions of wires as received and diameter of stainless steel core after coating removal was measured with optical profile projector. Results: Significant differences exist in static and kinetic friction between tested wires in experimental conditions. Dimensions of all coated wires differ significantly from reported by manufacturers’ sizes. Conclusions: Type of esthetic coating effects frictional characteristics of orthodontic wires and should be considered by clinicians for predictable treatment outcomes.

▼ Hypothesis: There is no statistically significant mean difference in vertical dimension changes between the quad helix expander and the bonded rapid palatal expander during phase I treatment for growing skeletal class I and class II
subjects.
Objective: The objective of this study was to determine if there is a significantly different effect on vertical changes during palatal expansion in phase I treatment using a quad helix expander or a bonded rapid palatal expander in growing skeletal class I and class II subjects.
Methods: This retrospective study looked at two treatment groups, a quad helix expander group and a bonded rapid palatal expander group, before treatment (T1) and after the completion of phase I treatment (T2) to assess changes in the vertical dimension after palatal expansion treatment. Each treatment group was also compared to an untreated predicted growth model. All subjects were growing patients with either a class I or class II skeletal pattern. Lateral cephalograms taken before treatment and after the completion of expansion and phase I treatment were traced using Dolphin Imaging, and these cephalometric tracings were used to analyze the changes in vertical dimension.
Results: When the quad helix and bonded rapid palatal expander groups were compared to each other, no difference was found at T1, but significant differences at T2 were found for the variables convexity, lower facial height, total facial height, facial axis, and FMA. When the two treatment groups at T2 were compared to their respective untreated predicted growth models, a significant difference was found for the variable lower facial height for the quad helix group and for the variable U6-PP for the bonded expander group.
Conclusions: The differences found at T2 between the two groups suggested that the quad helix expander had more control over skeletal vertical measurements than the bonded rapid palatal expander, based on this sample. When comparing treatment results to untreated predicted growth values, the quad helix expander appeared to maintain lower facial height better than the bonded rapid palatal expander, and the bonded rapid palatal expander appeared to maintain the
maxillary first molar vertical height better than the quad helix expander. Overall, both the quad helix expander and the bonded rapid palatal expander showed minimal vertical changes during palatal expansion treatment.

▼ Hypothesis: Tooth size ratios for an ideal occlusion proposed by Bolton 1958 are significantly different than the ratios obtained from American Board of Orthodontics (ABO) certified orthodontically treated cases. Objectives: To compare tooth size ratios from cases that passed ABO exam, with Bolton’s tooth size ratios. To determine the correlation between tooth size ratios and over jet, overbite, anterior tooth inclination, and thickness. Methods: 94 stone models and cephalometric radiographs of finished cases that passed ABO examination were used to measure the anterior and the overall ratios and 52 cases were used for the overall ratio. The Mesiodistal width of each tooth, overjet, overbite, and teeth proclination was measured. Results: T-test shows both overall and anterior ratios have no significant difference from Bolton ratios. The test of correlation showed that both overall and anterior ratios had a significant correlation with overjet, overbite, and upper incisors thickness. Tooth angulation shows no significant correlation with tooth size ratios. Conclusions: Bolton's tooth size ratios are identical to those obtained by ABO certified cases. There is a relatively low inverse correlation between tooth size ratios and overjet, overbite, and upper incisors tooth thickness. Funding: Thanks to Orthopli Corp. for donating the digital gauge caliber. IRB protocol: 20120640-69258-1

▼ Hypothesis: It was hypothesized that a significant association exists between maxillary central incisor inclination and the discrepancy between actual tooth length and tooth length measured on a panoramic radiograph. Objective: The purpose of this study was to determine if the discrepancy between the actual maxillary central incisor length measured on a cone beam computed tomograph (CBCT) and the maxillary central incisor length measured on a panoramic radiograph is associated with the tooth’s buccolingual inclination as determined from a lateral cephalogram. Methods: Digital panoramic radiographs, lateral cephalograms, and CBCT scans were taken on thirty-five dry skulls obtained from the
University of
Illinois at
Chicago College of Dentistry. The lateral cephalograms were used to record the maxillary central incisor inclination with respect to two different reference lines, the sella-nasion line (U1SN) and the Frankfort horizontal line (U1FH). The vertical length of the most facially-positioned central incisor was measured on the panoramic and CBCT images of each skull. The differences in maxillary central incisor length from panoramic to CBCT image were recorded (DU1PACT). Correlation testing was conducted to assess if a significant association exists between DU1PACT and U1SN as well as betweetn DU1PACT and U1FH. Results: Significant, positive correlations were found between DU1PACT and U1SN as well as between DU1PACT and U1FH (p<0.05). Conclusions; The cephalometric inclination of the maxillary central incisors in this study were positively associated with the difference between their actual length as determined from a CBCT scan and their lengths determined from a panoramic radiograph. It is suggested that this association be considered in all studies involving tooth length assessment on panoramic images.

▼ We hypothesize that the three-dimensional asymmetry analysis as postulated by Katsumata et al will reveal more diagnostic information for individuals with HFM than traditional cephalometric analyses. We further hypothesize that there will be a direct relationship between mandibular asymmetry values and the corresponding Pruzansky-Kaban score. The objectives in this study are to: evaluate HFM in three-dimensions using an asymmetry index classification system, determine which mandibular segments are more affected, and compare this new classification approach to established descriptive classification systems. The experimental group consisted of 16 individuals with diagnosed HFM that had initial CBCT scans. Established cephalometric landmarks were indentified on the images and three-dimensional measurments were gathered. These measurments were then inserted into an equation to calculate the asymmetry index value for each landmark. Bilateral linear measurements of the mandibular body and ramus were compared. Finally, mandibular asymmetry values were compared to the corresponding Pruzansky-Kaban score. All skeletal landmarks were found to have significantly(p<0.05) larger asymmetry values when compared to unaffected controls. The mandibular body and ramus on the affected side were significantly(p<0.001) smaller than the unaffected side. A positive correlation(p=0.008) was found between the mandibular asymmetry value and Pruzansky-Kaban score. The study showed that individuals with HFM have asymmetry in the maxilla, mandibular body, and mandibular ramus. The study also introduced a new method for classifying HFM quantitatively.

▼ Hypothesis: Oropharyngeal 2D and 3D airway variables will be associated with MAS treatment response in terms of change in respiratory disturbance index (RDI) and change in minimum oxygen desaturation (SaO2). The association between oropharyngeal 2D and 3D airway variables with MAS treatment response will depend on sleep position, sleep state, mandibular protrusion, initial OSA severity, BMI, and neck circumference.
Objective: To identify the association between oropharyngeal airway dimensions derived from cone beam computed tomography (CBCT) and MAS treatment response, and to determine whether it is affected by mandibular protrusion, sleep state, sleep position, initial OSA severity, BMI, and neck circumference.
Methods: Thirty-three adults were assessed retrospectively. Dolphin 3D was used to measure the airway in pretreatment CBCTs. Airway volume, length, and minimal cross-sectional area (CSA) were calculated, as well as transverse and A-P dimensions and minimal CSA location. Pre- and post-treatment polysomnograms (PSGs) assessed OSA severity via RDI, and changes in minimal SaO2, supine and non-supine RDI, and NREM and REM RDI.
Results: This study included 23 males and 10 females. Ten, fifteen, and eight initially presented with mild, moderate, and severe OSA, respectively. Oropharyngeal 2D and 3D airway variables were associated with treatment response. Multivariate models explained treatment response, wherein initial OSA severity was a primary predictor in four models, and the combination of total airway volume and initial BMI were predictors in two models.
Conclusions: Patients with higher initial OSA severity and smaller airway volumes may have increased response to MAS therapy. Decreases in airway volume due to skeletal rather than soft tissue obstruction may enable better MAS treatment response. Since MAS targets upper airway, patients with superior airway constriction illustrate increased treatment response potential as well as decreased titration to achieve desirable outcome.

▼ Purpose: The aims of this study were to determine (1) how microtensile bond strength (μTBS) is affected by proanthocyanidins (PACs) from an enriched fraction of a grape seed extract (EGSE) when incorporated as a primer in the dentin bonding process and (2) whether EGSE overcomes the deleterious effect of saliva contamination on the resin-dentin bond strength in primary molars.
Methods: extracted primary molars were ground to expose sound coronal dentin. The teeth were divided into four groups: (1) Control group, (2) 6.5% EGSE primer prior to adhesive, (3) Contamination with saliva after etching, (4) 6.5% EGSE primer prior to adhesive and contamination with saliva after etching. Samples were sectioned and evaluated for μTBS.
Results: The 6.5% EGSE used as a primer before bonding showed no significant difference in μTBS compared to controls in both non-contaminated and contaminated groups (p=0.46). There was a significant difference between control groups and groups with salivary contamination (F (1,201) = 24.321, p< 0.001). There was no difference of saliva-contaminated samples between control and 6.5% GSE treatment (F(1, 201)= 3.380, p=0.07).
Conclusions: EGSE did not enhance TBS in composite restorations for primary teeth.

▼ In this retrospective, cross-sectional study, our objective was to use a previously published cephalometric method to measure the maxillary and mandibular molar and premolar dentoalveolar heights of orthodontically untreated male and female subjects past their peak growth spurt as determined by CVMS stage V. Methods: A total sample size of 218 subjects with full permanent dentition that met defined inclusion and exclusion criteria, and grouping criteria were analyzed. Approximately 50% of the sample was obtained from the
University of
Illinois-
Chicago Department of Orthodontics, and 50% from private offices. The sample was diverse in ethnic backgrounds and representative of an urban practice setting, with ages ranging from 13-56 years old. Using cephalometric gropuing criteria, subjects were then assigned to one of the following groups: Class I normodivergent, Class II hyperdivergent or hypodivergent, or Class III hyperdivergent or hypodivergent. Cephalometric images were traced using Dolphin Imaging (v11.7) and data was analyzed using independent t-tests, one-way ANOVA, and Bonferroni post-hoc tests (p<0.05), using SPSS statistical software (v22.0). Results: Several statistically significant differences in mean dentoalveolar height measurements were found when comparing Class I subjects to the other groups, and when comparing hyperdivergent groups to hypodivergent groups, and when comparing Class II groups to Class III groups. Statistically significant differences ranged from 1.11mm-4.55mm. Gender dimorphism was also demonstrated, both in mean differences in dentoalveolar heights, and in the magnitude of differences between groups of the same gender. Because of the gender dimorphism, all groups were also separated by gender. Conclusions: The comparisons in this study showed strong trends of short maxillary posterior dentoalveolar heights in Class II hypodivergent subjects, and short mandibular posterior dentoalveolar heights of Class III hyperdivergent subjects.

▼ Hypothesis: There are no statistically significant mean differences in patient age at stages A-H of third molar mineralization in terms of sex, race, and quadrant. Objective: In forensic examination, observing stages of the dentition results in highly accurate age assessment but becomes more difficult once dental development is complete. This study evaluated the use of panoramic radiographs to determine chronologic age range utilizing the developmental stages of third molars. Methods: A total of 2000 panoramic radiographs of patients between the ages of 4-22 taken from years 2013-2015 at the
University of
Illinois College of Dentistry were analyzed. The development of third molars were classified into eight stages (A-H) according to Demirjian et al.’s classification method. The majority of subjects did not report ethnicity, however 213 identified as Hispanics. Differences between the chronological age of third molar mineralization were then compared among sex and quadrants. Results: The subjects’ mean age was 13.03 ± 1.68 years for males (392 subjects) and 13.19 ± 1.56 years for females (607 subjects). Hispanic males showed statistically significant lower mean age than Hispanic females at Q4 stage B (10.22 ± 1.39 vs 11.67±0.84) and Q1 stage D (12.73 ± 1.19 vs 13.47±1.12), p-values= 0.021 and 0.038, respectively. Otherwise, there were no statistically significant mean differences in age between Hispanic males and females for any other classification stage. The 95% confidence interval (CI) on age for each stage in all four quadrants was investigated and a narrow range between upper and lower boundary was observed. Conclusions: The majority of the results indicate no significant mean age differences in third molar mineralization among all four quadrants in both males and females. Panoramic radiographic assessment of third molar mineralization is a useful tool for age estimation in children and young adults. Funding: N/A. IRB/ACC protocol: IRB 2015-0892
