The purpose of this study was to evaluate the sealing properties of four root canal sealers. Forty-eight maxillary central incisors were instrumented with Profile rotary instruments. They were randomly divided into four groups (n = 12) and filled using lateral condensation with one of the four sealers: Sealapex, Pulp Canal Sealer, AH 26, and Ketac-Endo. The apical leakage was measured with a fluid filtration method and expressed as L s-1 KPa-1. The teeth filled with Sealapex displayed a higher apical leakage (8.42 ± 4.2 10-11 L s-1 KPa-1) than those filled with AH 26 (2.10 ± 1.39 10-11 L s -1 KPa-1), Pulp Canal Sealer (0.17 ± 0.09 10 -11 L s-1 KPa-1) or Ketac-Endo (0.32 ± 0.24 10-11 L s-1 KPa-1) (p < 0.01). No statistically significant difference was found among AH 26, Pulp Canal Sealer, and Ketac-Endo. No correlation was found between the sealing efficiency of the four sealers and their adhesive properties recorded in a previous study.
