Background: Successful endodontic treatment depends on effective cleaning, shaping, and three-dimensional obturation of the root canal system. Root canal sealers play an essential role in achieving a hermetic seal by filling the space between gutta-percha and dentinal walls. Adequate bond strength between the sealer and dentin is important to prevent microleakage and dislodgement of the filling material. Recently, bioceramic sealers have been introduced with improved bioactivity and sealing properties compared with conventional sealers.
Aim: To compare the push-out bond strength of different root canal sealers including conventional and bioceramic materials.
Materials and Methods: This in vitro experimental study included 100 extracted single-rooted human premolars. The teeth were cleaned, decoronated, and instrumented using the ProTaper rotary system up to F3. The samples were randomly divided into four groups (n = 25) based on the sealer used: Group I – zinc oxide eugenol sealer, Group II – epoxy resin–based sealer, Group III – calcium silicate bioceramic sealer, and Group IV – premixed bioceramic sealer. The canals were obturated using the single cone technique with gutta-percha. After storage at 37°C for 7 days, the roots were sectioned to obtain dentin slices and subjected to the push-out bond strength test using a universal testing machine. The recorded values were expressed in Megapascals (MPa) and analyzed using one-way ANOVA and Tukey post hoc test.
Results: Bioceramic sealers demonstrated significantly higher push-out bond strength compared with conventional sealers (p < 0.001). The premixed bioceramic sealer showed the highest mean bond strength, followed by calcium silicate bioceramic sealer, epoxy resin sealer, and zinc oxide eugenol sealer.
Conclusion: Bioceramic root canal sealers exhibited superior bond strength to root dentin compared with conventional sealers and may provide improved sealing ability in endodontic obturation.
