Sealing ability of the vertical condensation with different root canal sealers
1Department of Endodontics, Dental School, Lebanese University, Beirut, Lebanon.
Abstract:
This study evaluated the influence of various root canal sealers on the quality of the apical seal of vertically condensed gutta-percha. One hundred and twenty human anterior teeth with single canals were used. After cleaning and shaping to an apical size 30 file, the teeth were divided into 4 equal groups of 30 teeth each and obturated with vertically condensed gutta-percha. In group 1, no sealer was used. In groups 2, 3, and 4, Kerr Pulp Canal Sealer, Roth 801, and AH 26 were used, respectively. Apical microleakage was determined using pressurized fluid filtration measured at different time intervals up to 24 wk. The no-sealer group showed significantly more apical leakage than the other groups. Kerr Pulp Canal Sealer was significantly better than Roth 801 and AH 26 at 24 wk.
