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.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalinfo:eu-repo/semantics/openAccessBioroot RCSCalcium Silicate-Base SealerCerasealEndosequence BC Sealer HiflowPush-Out Bond StrenghArticle36115115710.32067/GIE.2021.35.02.54N/A0008365135000082-s2.0-85132428319Q4
