Background: The present study compared bioceramic sealers in terms of dentinal sealing ability in the root canal. Materials & Methods: The present study was conducted on 30 permanent mandibular premolar teeth. Specimens were accessed using round diamond burs and then prepared using the crown-down. Specimens were obturated with gutta-percha ProTaper Next cone and bioceramic sealers (iRoot® SP, MTA Fillapex, and BioRoot RCS). The root canal using a scanning electron microscope to see the dentinal sealing ability and adaptation of each sealant. Results: In this study group I teeth used iRoot® SP, group II used MTA Fillapex, and group III used BioRoot RCS sealer. Each group had 10 teeth. We found that mean sealing ability of sealer in group I was 4.61, in group II was 42.3 and in group III was 3.80. Conclusion: Authors found that sealing ability of calcium phosphate silicate-based sealer is superior to that of both pure tricalcium silicate-based and tricalcium silicate- and resin-based sealer. Key words: Calcium phosphate, Dentine, BioRoot RCS sealer.
