Objective: The objective of this study was to analyze the voids formation difference of calcium silicate bioceramic-based sealers and calcium silicate pozzolan-based sealers with ultrasonic activation and without ultrasonic activation by 3D Micro-CT analysis. Material and Methods: Thirty-two samples of extracted single root lower premolars were given root canal filling using gutta-percha and calcium silicate-based sealers with or without ultrasonic activation. Void formation on sealers was evaluated by measuring the total voids of the root canal filling with micro-CT analysis. Group 1: calcium silicate-based sealer iRoot® SP (Innovative BioCeramix, Vancouver, Canada) without ultrasonic activation; group 2: calcium silicate-based sealer iRoot® SP (Innovative BioCeramix, Vancouver, Canada) with ultrasonic activation; group 3: calcium silicate pozzolan-based sealer Endoseal® MTA (Maruchi, Wonju, Korea) without ultrasonic activation; and group 4: calcium silicate pozzolan-based sealer Endoseal® MTA (Maruchi, Wonju, Korea) with ultrasonic activation. Statistical analysis used one-way ANOVA and post hoc Bonferroni. Results: Ultrasonic activated calcium silicate pozzolan-based sealer group showed the lowest voids formation through micro-CT analysis. Calcium silicate bioceramic pozzolan-based sealers have fewer voids formation significantly (p<0.05) compared to calcium silicate bioceramic-based sealers. The ultrasonically activated sealer groups also showed fewer voids formation significantly (p<0.05) compared to groups that were not activated by ultrasonic. Conclusion: Micro-CT analysis revealed calcium silicate pozzolan-based sealers with ultrasonic activation have the least voids formation on root canal fillings.
