采用液体转移法评价3 种根管充填剂(Endométhasone、AH-Plus、GuttaFlow)的根管微渗漏,通过扫描电镜观察根管壁与充填剂之间的结合特征.结果表明GuttaFlow组的微渗漏值最小,Endométhasone组的微渗漏值最大.3 种材料间比较均有统计学差异(P<0.05).扫描电镜下不同根管充填剂与根管壁的结合情况不同.GuttaFlow的根管封闭性能较其他2 组更佳.

This article was to study the micro-leakage of 3 different root canal sealers (Endomethasone, AH-Plus and GuttaFlow) by fluid filtration test, and to observe the micro-structure between walls of root canal and the sealers by SEM. The results indicated that the micro-leakage of GuttaFlow was the least and Endomethasone was the most. Statistics difference were found between all the groups. Different root canal sealer got different micro-structure between walls of root canal and sealers. So we consider that the canal sealing ability of GuttaFlow is the best among these sealers.
