The study's objective is to assess the bond strengths of four different endodontic sealers to root dentin using a push-out test technique. Sixty single-rooted teeth were selected and decoronated. Canal instrumentation was done using rotary files and divided into four groups (n = 15) based on the sealer used. Group 1: zinc oxide eugenol (ZOE)-based, Group 2: epoxy resin-based, Group 3: methacrylate-based, and Group 4: bioceramic. Following obturation with Gutta Percha, each tooth was prepared with root portions that were 2 mm thick at the apical and middle 1/3 so that universal testing equipment could measure the push-out bond strength. Tukey's post hoc tests and one-way ANOVA were used to examine the data. According to the results, group 4 had the strongest push-out relationship, followed by groups 3, 2, and 1, respectively. It can be concluded that the bioceramic sealers have superior bond strengths. Bioceramic sealers demonstrated the highest bond strengths to root dentin, outperforming methacrylate, epoxy resin, and zinc oxide eugenol sealers in the push-out test.
