Sealing ability of three bioceramic sealers using sealer-based obturation method after immersion in simulated body fluid.

Aim: The study aimed to evaluate and compare the apical sealing ability of three bioceramic sealers, i.e., BioRoot RCS, CeraSeal, and Bio-C sealer, using sealer-based obturation method after immersion in simulated body fluid (SBF).

Methodology: Eighty-eight extracted single-rooted mandibular premolars with mature apices and straight root canals were selected. Teeth were decoronated at 12 mm length from the apex. They were divided into 4 groups according to the sealer used (n = 22), i.e., control group (Group 1) - AH Plus (obturated using warm vertical compaction [WVC] technique) and experimental groups - Group 2 (BioRoot RCS), Group 3 (CeraSeal), and Group 4 (Bio-C sealer) (obturated using single-cone technique). Specimens in each group were further divided into two subgroups (n = 11) - Subgroup 1 (evaluation after 48 h) and Subgroup 2 (evaluation after immersion in SBF for 30 days). A dye penetration test was used for microleakage analysis using a stereomicroscope (10×). The collected data were statistically analyzed.

Results: After 48 h, the control group showed the least microleakage, and the difference was statistically significant compared to all experimental groups. After immersion in SBF for 30 days, no significant difference in microleakage was seen among all the groups.

Conclusion: The sealing ability of the bioceramic sealers with single-cone obturation when exposed to the SBF improved significantly after 30 days and was comparable to AH Plus using the WVC obturation technique. Thus, single-cone obturation with bioceramic sealers can be considered a viable alternative.
