Aim:This study aims to evaluate and compare microleakage at the occlusal wall and cervical wall in Class II cavities restored with one SonicFill Bulk Fill composite and two conventional Bulk Fill composites.Materials and Methods:Thirty freshly extracted teeth were divided into three groups of 10 teeth each. Standardized Class II cavities were made on the mesial and distal surfaces of each tooth and restored using SonicFill Bulk Fill composite and two conventional Bulk Fill composites, Tetric Evo Ceram, and X-tra fil. After storage, thermocycling and immersion in 0.6% rhodamine dye solution specimens were sectioned and evaluated for microleakage at the occlusal and cervical walls using confocal microscope.Statistical Analysis Used:Kruskal-Wallis test, Wilcoxon Signed-Rank test and Mann-Whitney U-test.Results:The results demonstrated that in the occlusal wall and cervical wall, SonicFill Bulk Fill composite, showed significantly less marginal microleakage than the other groups.Conclusion:Based on the results of this study, SonicFill Bulk Fill composite showed less microleakage than the other conventional Bulk Fill composites.

Endodontic treatment of teeth is now a common procedure across all age groups, either as a result of caries or trauma. Furthermore, as the number of adults undergoing orthodontic treatment increases, the number of orthodontic patients presenting with restored teeth or having endodontic treatment is on the rise. Diagnosis and treatment planning for these patients require an evidence based approach to achieve a good functional and esthetic results. Orthodontic treatments have profound effect on pulp and periodontal ligament which can lead to root resorption or loss of vitality which remain as orthodontic scars. Literature regarding occurrence of root resorption in vital teeth and teeth having endodontic treatment, the influence of trauma, the provision and outcome of endodontic treatment when attempted during the course of orthodontic therapy and the adjunctive role of orthodontics in facilitating good endodontic output are inconclusive till now. The integrated endodontic and orthodontic treatment in such situations will give optimum results. This article mainly focuses on orthodonticendodontic interactive tasks to be tackled that are often encountered in clinical practice which play an important role in treatment planning and its outcome.
