| Abstract Aim: To study the effect of calcium hydroxide as intracanal medicament on bond strength of AH Plus and Bioceramic sealer to root dentine. Material and Methods: forty single-rooted human teeth were prepared by ProTaper Next. The samples were randomly allocated into two groups (n=20 teeth): the control group (no intracanal medicament) and Calcium hydroxide. After one week, the intracanal medicament was flushed out, and each group was further divided based on the sealer used AH Plus or Bio-C. Root canals were obturated using lateral compaction technique and incubated again for two weeks. The roots sectioned into 2 mm slices from the coronal, middle, and apical thirds. Push-out bond strength was measured. Results were recorded in MPa and statistically analyzed. Result: Calcium hydroxide significantly reduced bond strength compared to control at the middle (AH Plus p = .049, Bio-C p < .001) and apical thirds (AH Plus p = .048, Bio-C p < .001). No significant differences were found at the coronal third. Conclusion: Calcium hydroxide reduced the bond strength of both AH Plus and Bio-C sealers to root dentine. | ||
