Abstract

Aim: The aim of the present study was to compare the push-out bond strength of CeraSeal Bioceramic sealer used with Gutta percha in single cone (SC), cold lateral compaction (CLC) and warm vertical compaction(WVC) obturation techniques.
Materials and Methods: Thirty single-rooted extracted mandibular premolars were selected and mechanically prepared by ProTaper Next rotary files. The canals were allocated into three equal groups (n=10) based upon the obturation technique as follow; Group I: Bioceramic sealer (CeraSeal) with single cone, Group II: Bioceramic sealer (CeraSeal) with cold lateral compaction technique, Group III: Bioceramic sealer (CeraSeal) with warm vertical compaction technique. Roots were sectioned transversally to a thickness of 1 mm at the middle third. The specimens were subjected to push-out test using the Universal Test Machine. The maximum load utilised at the time of dislodgment was recorded. Intergroup comparisons were performed by one-way ANOVA followed by Tukey’s post hoc test.
Results: WVC group showed the highest statistically significant mean push-out bond strength value (6.98±1.99) followed by CLC group (1.06±0.15), while the lowest value was presented in SC group (0.66±0.22) (p < 0.001).
Conclusions: CeraSeal Bioceramic sealer showed higher push-out bond strength when used in WVC technique compared to single cone and lateral compaction techniques.
