In the present study, dye leakage values were higher for groups irrigated with QMix (3.7±0.3 mm) than those irrigated with NaOCl and EDTA (2.9±0.3 mm) where MTA Fillapex was used as sealer. Similarly when Adseal was used as root canal sealer, dye leakage values for groups irrigated with QMix (3.4±0.3 mm) were higher than the groups irrigated with NaOCl and EDTA (2.1±0.4 mm).
