Paper Abstract

This study determined, in vitro, the coronal leakage of root canals evaluating the effect of smear layer removal by either EDTA or laser. Two sealers were also compared. Sixty-four canines were instrumented with the step-back technique and irrigated with 10 ml of 1% sodium hypochlorite. In Group 1, 10 teeth were sealed with Sealer 26 and 10 teeth were sealed with Grossman cement with no attempt of smear layer removal. Group 2 received a final irrigation of 15 ml of 17% EDTA, and was sealed as in Group 1. Group 3 received Er:YAG laser application (140 mJ, 15 Hz and 42 J), and sealed as in Group 1. Root canals sealed with Sealer 26 had significantly less coronal leakage than Grossman cement (P<0.05). Coronal leakage afte smear layer removal with 17% EDTA or Er:YAG laser was not statistically different (p>0.01).
