Aim: This study aims to evaluate the effect of different obturation techniques [single cone (SC) and warm vertical compaction (WVC)] on the push-out bond strength (PBS) of gutta-percha (GP) with three calcium silicate-based sealers (CSBSs).

Methodology: Sixty single‑rooted mandibular premolars were selected and decoronated to obtain a standardized root length of 16 mm. The canals were instrumented using VDW.Rotate system and were assigned into six equal Groups based upon the CSBS and obturation technique used following; Group 1 and Group 2; BC Sealer HiFlow (HiFlow; Brasseler USA) with SC and WVC, Group 3 and Group 4; CeraSeal (Meta Biomed Co., Cheongju, Korea) with SC and WVC, Group 5 and Group 6; BioRoot RCS (Septodont, Saint‑Maur‑des‑Fosses Cedex, France) with SC and WVC. Roots were sectioned transversally at the thickness of 1±0.1 mm in thickness at 5 and 10 mm from the apex. The specimens were subjected to PBS test using a universal test machine at a loading speed of 0.5 mm/ min examined for their failure modes. Statistical analysis was performed using Kruskal-Wallis and multiple comparison tests.

Results: BioRoot-WVC Group was a significantly lower PBS value than other Groups at 5 and 10 mm from the apex (p<0.05). At 5 and 10 mm from the apex, no significant difference in PBS was found among the BC Sealer HiFlow and CeraSeal sealers obturated using two different techniques (P>0.05). The most common failure mode found in all Groups was a mixed failure.

Conclusions: WVC significantly reduced the PBS of the BioRoot RCS sealer compared to SC technique, but this was not significant with the BC Sealer HiFlow and CeraSeal.
