ABSTRACT
Aim:
To clarify the influence of 5.25% sodium hypochlorite disinfection of gutta-percha cones onleakage and to compare the outcomes of two sealability assessment methodologies (fluid filtrationand dye penetration methods).Methods:
Thirty teeth were prepared and filled using the guttaperchalateral condensation technique. Group I was filled with gutta-percha cones disinfectedwith sodium hypochlorite 5.25%, while Group II was filled with cones that were not disinfected.Apical leakage was measured using (a) fluid filtration technique and (b) linear measurement ofdye penetration after clearance.Results:
The Students t-test showed no significant differencebetween the groups for both techniques (p<0.05).Conclusions:
Both methodologies employed,even with the inherent limitations, were capable of identifying sealing failures. The disinfection ofgutta-percha cones with 5.25% sodium hypochlorite did not alter apical leakage.
