Abstract

Push-out bond strength (POBS) and failure analysis of gutta-percha and Martens hardness (MH) of canal dentin sealed with Bio-ceramic sealer (BCS). Specimens underwent endodontic treatment. Based on the method of disinfectants, specimens were classified into 4 groups. Group 1:5.25% NaOCl+Q-mix, group 2:ECYL+Q-mix, group 3:LGE+Q-mix, and group 4:RBP+Q-mix. Before obturation MH was assessed using a microhardness tester. Canals were obturated, and sealed with Bio-Root RCS. Each root was cut horizontally in 2 mm thickness and placed under the indenter of the universal testing machine. One-way analysis of variance and the Post Hoc Tukey test for group comparisons as statistical analysis. Samples with (5.25% NaOCl+Q-mix) displayed the highest bond integrity of BCS (8.00±0.24 MPa). The lowest POBS was demonstrated by the apical section of group 4 (RBP+Q-mix 2 in 1) (4.10±0.94 MPa) specimens. Group 2 (ECYL+Q-mix) and group 3 (LGE+Q-mix) exhibited comparable outcomes of bond scores to group 1 specimens (p > 0.05). MH was significantly lower in group 4 compared to group 1, group 2, and group 3 (p <0.05). The bond strength of BCS and MH of canal dentin is influenced by the type of irrigation.
