Push-Out Bond Strength Failure Analysis of Gutta-Percha and Martens Hardness of Radicular Dentin Disinfected Using Rose Bengal, Er, Cr: YSGG, Sealed with a Novel Bio-Ceramic Sealer

Push-out bond strength (POBS) and failure analysis of gutta-percha and Martens hardness (MH) of canal dentin IP: 203.8.109.20 On: Tue, 21 Mar 2023 09:07:20 sealed with Bio-ceramic sealer (BCS). Specimens underwent endodontic treatment. Based on the method of Copyright: American Scientific Publishers disinfectants, specimens were classified into 4 groups. Group 1:5.25% NaOCl+Q-mix, group 2:ECYL+Q-mix, Delivered by Ingenta 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.
