本研究旨在评估和比较使用一种SonicFill Bulk Fill复合材料和两种传统Bulk Fill复合材料修复的II类洞中咬合壁和颈部壁的微渗漏。将30颗新拔出的牙齿分为三组，每组10颗牙齿。在每颗牙齿的近中和远中表面制作标准化的II类洞，并使用SonicFill Bulk Fill复合材料和两种传统的Bulk Fill复合材料Tetric Evo Ceram和X-tra fil进行修复。保存、热循环和0.6%罗丹明染料溶液浸泡后，将标本切片，用共聚焦显微镜评价咬合和颈部壁的微渗漏。Kruskal-Wallis检验、Wilcoxon符号秩检验和Mann-Whitney U检验。结果表明，在咬合壁和颈部壁中，SonicFill Bulk Fill复合材料显示出比其他组显著更少的边缘微渗漏。根据本研究的结果，SonicFill Bulk Fill复合材料显示出比其他传统Bulk Fill复合材料更少的微渗漏。
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. 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. Kruskal-Wallis test, Wilcoxon Signed-Rank test and Mann-Whitney U-test. The results demonstrated that in the occlusal wall and cervical wall, SonicFill Bulk Fill composite, showed significantly less marginal microleakage than the other groups. Based on the results of this study, SonicFill Bulk Fill composite showed less microleakage than the other conventional Bulk Fill composites.
