Material and Methods: 65 single-canal teeth were instrumented with ProTaper rotary instruments. The specimens were randomly divided into two groups according to sealer type. Each group was randomly subgroup into four groups according to the final irrigation activation protocol; Nd:YAG laser, Vibringe, EndoActivator, Conventional Endodontic Needle Irrigation (n=6). The root canals were obturated with single gutta-percha and BioRoot RCS or MTA Fillapex. The teeth were sectioned into 1-mm-thick disc by using Isomet. Push-out force was applied until dislocation of obturating material and the bond strength value obtained was recorded as Newton. Data were analyzed using two-way Anova and Tukey HSD test (P = 0.05). Results: A significant interaction was found between sealers and irrigation methods (p <0.05), with the highest bond strength in the apical conventionel needle irrigation group and in the coronal Nd:YAG laser and control groups. The BioRoot RCS had higher bond strength values than the MTA Fillapex (p = 0.00). Higher bond strength values were observed from apical to coronally (p <0.05). Conclusion: Based on the present results, within the limitations of this study, calcium silicate-based sealer (MTA Fillapex and BioRoot RCS) showed better bond strength in the presence of the smear layer.}, number={2}, publisher={Necmettin Erbakan Üniversitesi}, organization={Selçuk Üniversitesi BAP Koordinatörlüğü}
