摘　　要：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 （Endométhasone, 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 microleakage of GuttaFlow was the least and Endométhasone 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.
