摘要/Abstract

摘要： 目的: 利用micro-CT评价不同封闭技术对根管充填质量的影响。方法: 选取单根管上颌前牙40颗,截冠后,使牙根长度为12 mm。利用ProTaper预备至F3,将处理好的样本随机分为4组（n=10）,用牙胶尖和（或）iRoot SP分别使用冷侧压法、热牙胶法、单尖法、纯糊剂法完成充填。1周后,应用micro-CT扫描并测量分析根管内存在的间隙,计算各组存在气泡的横截面比例和充填材料整体、冠1/3、中1/3、尖1/3的体积比,采用SPSS 20.0软件包对数据进行统计学分析。结果: 热牙胶组存在气泡的横截面比例最少(P<0.05);整体、冠1/3、中1/3热牙胶组的充填材料体积比最大(P<0.05),而尖1/3纯糊剂组的充填材料体积比最大（P<0.05）,其他各组间均无显著差异。结论: 所有封闭技术均不能避免气泡产生,热牙胶法充填质量最高。

Abstract: PURPOSE: The aim of this study was to evaluate the quality of different root canal obturation techniques by micro-CT. METHODS: Forty single-canal upper incisors were collected and decoronated to obtain 12 mm root segments. The root canals were prepared by using ProTaper rotary files and allocated into 4 groups randomly（n=10）, then obturated with gutta-percha and(or) iRoot SP by cold lateral compaction (CLC), continuous wave condensation (CWC), single core (SC), sealer-only buckfill (SoB) techniques, respectively. Each tooth was then scanned with micro-CT, and the percentage of 3D volume and 2D slices of voids and gaps were calculated 1 week later. The data were analyzed using SPSS 22.0 software package. RESULTS: Percentage of cross-sections with voids and gaps in CWC group was significantly less than others (P<0.05) , and it had a significantly greater filling area in 3D volume in whole root canal, middle third and coronal third levels (P<0.05), while SOB group had the largest filling quality in apical third levels (P<0.05). CONCLUSIONS: No filling technology can avoid voids. CWC technology provides the best filling performance.
