| 摘 要： | 目的:比较纳米瓷充填材料和复合树脂充填乳牙V类洞边缘微渗漏的影响以及固化效率的差异。方法:第一部分为微渗漏实验,选取滞留拔除的上颌乳前牙20颗,唇侧制备V类洞,随机分为A、B两组,分别用Composan LCM和Filtek~(TM) Z350充填,亚甲基蓝染色处理,24 h后使用体式显微镜观察,测量染料渗入深度为微渗漏值,每组各选2个样本扫描电镜观察充填体与牙体组织间粘结情况。第二部分为显微硬度实验,分别用两种充填材料制作模块各9个,记为A、B两组,材料模块光固化24 h后使用显微硬度仪检测充填材料的固化效率。结果:Composan LCM组微渗漏值明显低于Filtek~(TM)Z350组(P0.05);扫描电镜下观察Filtek~(TM) Z350组充填材料与牙体组织间可见裂缝,界面参差不齐,有不连续的小断裂,Composan LCM组界面连续均匀,未见明显裂缝;两组充填材料的固化效率无显著差异(P0.05)。结论:纳米瓷充填材料和复合树脂均可用于乳牙龋洞充填,使用纳米瓷充填材料可减少微渗漏。
