Aim: To compare the push out bond strength of BioRoot RCS and Adseal using universal testing machine.

Methods and Material: After decoronating 30 extracted single-rooted teeth were decoronated, Instrumentation was done upto F3 file (universal protaper, Dentsply). The teeth were divided into three groups (n=10) based upon the sealer used. Group A: Epoxy resin based sealer (Adseal), Group B: Bioceramic sealer (BioRoot RCS), and Group C: zinc oxide eugenol (ZOE) based sealer (Root canal sealer, DPI, India). Manipulation and application of the sealer was done as per the manufacturer instructions. All the teeth were obturated using F3 gutta-percha (Dentsply- Maillefer, Ballaigues, Switzerland). After obturation, each tooth was prepared with root sections of 2 mm thickness at middle 1/3 and apical 1/3 for testing push out bond strength using universal testing machine. Data were analyzed using two-way ANOVA and multiple post hoc tests.

Results: The highest bond strength was found in BioRoot RCS followed Adseal and the lowest bond strength was found in ZOE based sealer.
