Aim and objective: The aim and objective of this study was to evaluate the three different root canal sealers that influenced the failure modes of fiber post luted with self-adhesive resin cement. Under a stereomicroscope, the influence of three different endodontic sealers on the failure modes of fiber post luted with self-adhesive resin cement was evaluated and compared. Materials and methods: In this study, 45 mandibular premolars were tested. To standardize the root length, the samples were decoronated at the cementoenamel junction. Working length was determined using the Ingles method. The samples were separated into three groups after cleaning and shaping, and each group was obturated with gutta-percha and the respective sealer. For 1 week, all of the samples were incubated at 37°C. Drills given by the manufacturer were used to prepare the post area, and the appropriate post was luted with self-adhesive resin cement. The samples were incubated at 37°C for 1 week. Following that, the samples were sectioned into 2-mm-thick slices at the coronal, middle, and apical levels. The universal testing machine was used to execute the push-out test, and the mode of failure was investigated under a stereomicroscope. Result: Bio-C sealer group showed maximum mixed failure. Maximum cohesive failure was observed in the AH Plus group, and maximum adhesive failure was observed in the mineral trioxide aggregate (MTA) Fillapex group. Conclusion: The group where the Bio-C sealer was used showed more amounts of mixed failure and better bond strength in comparison with AH Plus sealer and MTA Fillapex sealer.
