摘要/Abstract

摘要： 目的： 应用显微CT (micro-computed tomography,Micro-CT) 评价不同冲洗液联合声波荡洗对后牙弯曲根管内氢氧化钙的清除效率。方法： 收集2023年10月—2024年2月在上海交通大学医学院附属第九人民医院口腔综合科门诊拔除的磨牙20颗（根管数n=48）,按照根管治疗标准流程,使用镍钛器械完成预备后,在根管内置入氢氧化钙。1周后,根据不同冲洗方法将样本随机分入6组（n=8),即先分为次氯酸钠组、17%EDTA组和70%乙醇组3组,每组再分为使用或不使用声波荡洗2个亚组。冲洗前、后使用Micro-CT重建根管系统,使用不同颜色标记独立根管,计算根管各段氢氧化钙体积,比较各组氢氧化钙清除率。采用SPSS 19.0软件包对数据进行统计学分析。结果： 6组均无法去净根管内氢氧化钙,70%乙醇组去除氢氧化钙后剩余体积显著小于其余2组（P<0.05）。在乙醇亚组内,声波震荡组与注射器组去除效率无显著差异（P>0.05）。结论： 70%乙醇能增加弯曲根管内氢氧化钙去除效率。

Abstract: PURPOSE: To evaluate the efficacy of micro-computed tomography(Micro-CT) in removing calcium hydroxide from posterior curved root canals. METHODS: Twenty molar teeth (48 root canals) extracted at the Department of General Dentistry, Shanghai Ninth People's Hospital between December 2023 and February 2024 were collected. After preparing by Ni-TI instruments M3 according to standard root canal treatment procedures, calcium hydroxide was injected into the root canals. One week later, the samples were randomly divided into 6 groups(n=8) based on different irrigation methods: sodium hypochlorite group, 17% EDTA group and 70% ethanol group. Each group was further divided into 2 subgroups with or without sonic vibration. Micro-CT was used to reconstruct the root canal system before and after irrigation, with independent root canals marked using different colors. The root canals were categorized as upper segment, middle segment, and apical segment. The volume of calcium hydroxide in each segment was calculated, and the clearance rate of calcium hydroxide in each segment was compared. SPSS 19.0 software package was used for statistical analysis. RESULTS: Calcium hydroxide could not be completely removed from any of the 6 groups tested. The removal efficiency of calcium hydroxide by ethanol in the apical region was higher than that achieved by other two groups(P<0.05). In the ethanol subgroup, there was no significant difference in removal efficiency between sonic vibration and syringe techniques(P>0.05). CONCLUSIONS: Using 70% ethanol enhances the removal efficiency of calcium hydroxide in curved root canal.
