摘要： 目的:扫描电镜下比较声波充填术与分层充填术对树脂微渗漏的影响。方法:选取20个离体牙在邻牙合面制备3 mm×4 mm x5 mm窝洞,利用Sonicfill声波充填及分层充填术充填窝洞,光固化后并随机分为A组和B组。用2%亚甲基蓝溶液浸染1周,扫描电镜下观察试件剖面(近远中向),观察染液渗入深度,评价微渗漏程度,并对检测结果进行统计学分析。结果:A、B组微渗漏差异无统计学意义。结论:声波充填术比分层充填术更节省操作时间,可获得与分层充填术相当的边缘封闭性。

Abstract: Objective: To compare the microleakage of composite resin restorations using a sonicfill system and a layered filling technology. Methords: Class-Ⅱcavities (3 mm×4 mm×5 mm) were prepared on 20 freshly extracted molar teeth. The teeth were randomly divided into 2 groups with 10 teeth each. Group A was restored with Sonicfill system. Group B was restored with the traditional way. After restoration, all teeth were stained with 2% methylene blue solution for 1 week. The depth of methylene penetration was measured under the scanning electron microscope. Results: There were no significant differences between group A and B. Conclusions: The new Sonicfill system was the same as the traditional layered filling technology in the microleakage of composite resin restoration.
