Hermetic sealing of the root canal is the most desirable outcome of any root canal treatment, but almost always the filling of the root canal is defective, which is a multifactorial outcome. One such factor majorly influencing the obturation is the root canal sealer used.
The present study was done for evaluating microleakage in different root canal sealers.
Sixty extracted human single rooted teeeth were used in this in-vitro study. Sealers tested for microleakage in this study were zinc oxide eugenol based sealer, Sealapex, AH Plus, MTA Plus, EndoRez, Endosequence BC. All the specimens were examined under stereomicroscope for microleakage and the obtained data were statistically analysed using One-way ANOVA test and Tukey's multiple comparision tests using the software GraphPad Prism 7.02.
The Endosequence BC group showed the least dye leakage and the highest leakage was seen in Zinc oxide Eugenol based sealer.
Bio ceramic salers being hydrophilic show better sealing ability compared to resin based and eugenol based sealers.
根管的严密封闭是任何根管治疗最理想的结果，但根管充填几乎总是存在缺陷，这是一个多因素导致的结果。其中一个主要影响充填效果的因素是所使用的根管封闭剂。
本研究旨在评估不同根管封闭剂的微渗漏情况。
本体外研究使用了60颗拔除的人单根牙。本研究中测试微渗漏的封闭剂有氧化锌丁香酚类封闭剂、Sealapex、AH Plus、MTA Plus、EndoRez、Endosequence BC。所有标本在体视显微镜下检查微渗漏情况，所得数据使用GraphPad Prism 7.02软件进行单因素方差分析和Tukey多重比较检验进行统计学分析。
Endosequence BC组显示出最少的染料渗漏，而氧化锌丁香酚类封闭剂的渗漏最多。
与树脂类和丁香酚类封闭剂相比，亲水性的生物陶瓷封闭剂显示出更好的封闭能力。
