Introduction: The aim of this study was to evaluate the effects of calcium hydroxide [Ca(OH)2] and propolis intracanal medicaments on the push-out bond strength of a resin-based sealer (AH Plus) to root dentin. Materials and Methods: After chemomechanical instrumentation using ProTaper rotary system, three groups of root canal specimens were prepared: 10 root canals were left untreated as controls (G1), 10 received Ca(OH)2intracanal medicament (G2), and another 10 received propolis intracanal medicament (G3). Canals were obturated with AH Plus and gutta-percha. After bond strength evaluation using push-out test, data was analyzed using 2- way ANOVA and Tukey post hoc tests (P = 0.05). Results: At coronal and middle thirds, there were no significant differences in bond strength among the three groups (P > 0.05). At apical third, G3 was significantly superior to G2 and G1 (P < 0.05), but there was no significant difference between G2 and G1 (P > 0.05). Conclusion: The use of propolis as an intracanal dressing material, with AH Plus used as the sealer in endodontic therapy was shown to have better sealer-dentin interfacial bond strength. |
