Trends in Resin Composite Restoration Repair Teaching in Dental Colleges in Pakistan

Abstract Background The paradigm shift from replacement to repair of defective resin composite restorations to implement minimal intervention approaches has been popular. Therefore, the teaching of composite repair strategies is included in contemporary dental curricula across the globe. Methods A validated 18-item questionnaire pertaining to existing educational practices related to the teaching of defective composite restorations repair was acquired form dental colleges in Pakistan. Results The response rate was 63% and the majority of dental colleges (67%) reported that they have included the teaching of composite restorations repair in the curricula, where four colleges (33%) implemented only didactic teaching and eight colleges (66%) reported a combination of didactic teaching and clinical training. The composite repair indications taught included tooth substance conservation 100% (12), reduced cost to patient 84.3% (10) and dentist 100% (12), reduced iatrogenic pulpal damage 100% (12), and reduced chair side treatment time 91.3% (11), restoration-related defects (66% preferred repair), anterior tooth fracture from incisal/proximal margin (80% teach repair), and in case of posterior tooth cusp fracture (20% teach repair). Our results revealed that the choice of mechanical and adhesive substrate surface conditioning depended on case selection. Conclusion The teaching of defective composite restorations repair was less widespread and certain variations in teaching were identified. Nearly all dental colleges reported to incorporate current evidence of minimum invasive strategies of composite repair in curricula in future.

Composite Restoration

Objectives: the purpose of this study was to evaluate the knowledge among dental students at King Khalid University, Jazan University, and Najran University in the kingdom of Saudi Arabia about when to repair or replace defective direct composite restoration. Materials and Methods: A questionnaire-based survey was formulated, pursuing the information about management (repair/replacement) of defective composite restorations and distributed among 200 dental students of three universities in the southern region of the kingdom of Saudi Arabia.The data were collected with the help of an online questionnaire. Data entry and the analysis were done using the statistical software package SPSS version 20.0. It was presented using descriptive statistics in the form of frequencies and percentages for qualitative variables, and range means and standard deviations for age, quantitative variable. Analytic statistics ere done using Chi-Square tests (x2) to test the significant difference between categorical variables. The level of significance, the p-value was 0.01 (p < 0.01). Results: The decision to choose between composite repair or replacement was influenced by whether this topic was taught to them at various undergraduate levels during Bachelor of Dental Surgery. The reason associated with the decision to repair defective composite restorations, 76% reported as cost-effective followed by Increased longevity (71%), the permanent filling (70%), patient’s preference for repair (65%), and least time consuming (50%). 67% participants preferred significantly (p<0.001) repair due to secondary caries in the previously restored tooth with composite, followed by the small surface defect in a composite restoration (65%), risk of pulpal damage significantly (p<0.001) in a defective composite restoration (62.5%) and more invasive and destructive treatment option (35%). More than half of respondents 123 (61.5%) reported that they were not taught about composite repair during the Bachelor of Dental Surgery. Conclusion: It is suggested with the help of our study that didactic and clinical training components regarding composite repair should be seriously included in the teaching curriculum of dental institutions as it is in the best interest of the patient. Dental students should be provided with clinical training on this topic so that they can follow proper decision-making protocols available during repair or replacement of defective resin composite restorations. Other researches in the future can be carried out for refining the guidelines and techniques utilized for composite repair.

SUMMARY This clinical report illustrates a conservative technique to mask enamel discolorations in maxillary anterior teeth caused by hypomineralization associated with enamel fluorosis and subsequent direct resin composite to improve the anterior esthetics. The treatment consisted of at-home whitening with 10% carbamide peroxide gel with potassium nitrate and sodium fluoride in a custom-fitted tray to mask the brown-stained areas, followed by resin infiltration to mask the white spot areas. An existing resin composite restoration in the maxillary right central incisor was subsequently replaced after completion of the whitening and resin infiltration procedures, whereas the two misaligned and rotated maxillary lateral incisors were built up with direct resin composite restorations to provide the illusion of adequate arch alignment, as the patient was unable to use orthodontic therapy.

Purpose: The aim of this in vitro study was to investigate effects of consistency of resin composite and insertion techniques on the formation of porosity or inclusion of air bubbles in resin composite restorations. Materials and Methods: Three resin composites (Tetric Ceram HB, Tetric EvoCeram and Prodigy) were selected to represent high, intermediate and low viscosity, respectively. Simulated Class I cavities prepared in acrylic resin blocks were restored with one of the composites using both hand-instrument insertion and injection insertion techniques. The restorations were sectioned longitudinally and microscopically examined for the presence of porosity. Results: The materials of low (Prodigy) and high Tetric Ceram HB) viscosity exhibited a significantly less porosity than the material of a mediate viscosity. The porosities of Prodigy and Tetric Ceram HB restorations were comparable regardless of the insertion technique. Tetric EvoCeram restorations inserted by the hand technique contained more porous inclusions than those inserted using the injection technique. Conclusion: Porosities inside resin composite restorations apparently arose during the filling process, and the consistency of resin composite influenced the porosity formation of the composite restoration. Injection insertion was not found necessary to reduce porosities.

SUMMARY This study evaluated the influence of three different application techniques on contact formation and voids in anterior resin composite restorations. Artificial ivorine teeth were randomly assigned to three experimental groups, with 20 specimens in each group. One operator performed all restorations using the Teflon tape, pull-through, or bioclear matrix technique. The treatment time required for each restoration was recorded. An examiner blinded to the treatment group performed the visual evaluation of six criteria, including proper contact formation. The restored teeth were cut to yield a total of 180 sections for microscopic evaluation. The Kruskal-Wallis procedure was performed to evaluate the significance of treatment time, number of voids, percent porosity area, and void diameter. There were significant differences in treatment time among the three groups (p<0.05). The bioclear matrix technique required the least time for the treatment of one diastema closure (p<0.05). The Teflon tape technique resulted in proper contact formation in 80% of specimens, a rate that was significantly lower than that associated with the pull-through and bioclear matrix techniques (p<0.05). Out of 540 imaging areas 160 images were free of voids. The number of voids and the percent porosity area were not significantly different among the three techniques (p>0.05). However, the mean void diameter was greater with the bioclear matrix technique compared to the other two techniques (p<0.05).
