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.
