Abstract: | This study aimed to investigate the effect of the heat-based obturation technique on the push-out bond strength of the classical bioceramic and new HiFlow sealer. Fifty single-rooted human mandibular premolars were obturated using one of the following techniques: (1) BC-SC; (2) BC-W; (3) HiFlow-SC; (4) HiFlow-W; and (5) AH Plus-W. Following obturation, specimens were sectioned into 1-mm-thick root slices 4 and 8 mm from the working length and were subjected to a push-out bond test using a universal testing machine and examined for their modes of failure under an inverted phase-contrast microscope. At both distances tested, there was no difference in the push-out bond strength among the four bioceramic groups (P > 0.05). The AH Plus-W group had lower bond strength than every other group at both distances from the working length. The most common failure mode was mixed failure. |
