The present study aimed to evaluate the sealing ability of three different calcium silicate-based materials in furcation perforations. Seventy-six human mandibular molar teeth were selected. Perforations were created in the center of the pulp chamber floor. The experimental teeth were randomly divided into three groups (n=22). Perforations were repaired with MTA Angelus, Endocem MTA, or EndoSequence BioCeramic Root Repair Material Fast Set Putty (BC-RRM Putty). Microleakage of the different repair materials to be tested was measured by computerized fluid filtration method at 24- and 72-hour intervals. For each time interval, no statistically significant difference was observed between the groups. For Endocem MTA and BC-RRM Putty groups, the difference between the leakage values measured at both periods was not statistically significant ( > 0.05). However, there was a significant difference for the MTA Angelus group ( < 0.05). All the calcium silicate-based materials used in the present study showed similar performance in repairing furcation perforations at 24- and 72-hour intervals.
本研究旨在评估三种不同的硅酸钙基材料对根分叉穿孔的封闭能力。选取了76颗人类下颌磨牙。在髓室底中央制备穿孔。将实验牙齿随机分为三组（n = 22）。分别用MTA Angelus、Endocem MTA或EndoSequence生物陶瓷根修复材料快速凝固糊剂（BC-RRM糊剂）修复穿孔。通过计算机流体过滤法在24小时和72小时间隔测量不同测试修复材料的微渗漏情况。在每个时间间隔，各组之间未观察到统计学上的显著差异。对于Endocem MTA组和BC-RRM糊剂组，两个时间段测量的渗漏值之间的差异无统计学意义（> 0.05）。然而，MTA Angelus组存在显著差异（< 0.05）。本研究中使用的所有硅酸钙基材料在24小时和72小时间隔修复根分叉穿孔时表现出相似的性能。
