Comparison of three root canal sealers by using fluid filtration model / 实用口腔医学杂志

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.
