| Aim: In this research, we assessed the sealing performance of various root canal sealers in conjunction with diverse obturation methods Subjects and methods: We selected ninety human mandibular premolars with single roots. The instrumentation was carried out for all specimens using ProTaper Next rotary files until reaching a size of 40/0.06. Irrigation was done by applying 5 mL of 5.25% NaOCl between each instrument, followed by a final rinse of 5 mL of 17% EDTA for 1 minute. Subsequently, we flushed the canals with a generous amount of sterile distilled water. We randomly selected samples and categorized them into three primary groups (n=30) based on the sealer employed. Each primary group was subdivided into three subgroups (n=10) depending on the obturation technique employed. In the groups using bioceramic sealers (Group B, C), the canals were intentionally left partially moist to aid in the setting process, thereby mimicking real-world clinical scenarios. To ensure the sealer fully set, the teeth were kept in an environment with 100% humidity at 37°C for a week. Afterward, the roots were transversely sectioned using a precision linear saw. The cut sections were then examined using a Scanning Electron Microscope. Results: Gap distance is significantly higher in the AH Plus sealer group and lower in the Vertical compaction technique. Conclusion: Bioceramic sealers showed better adaption to dentin and vertical compaction obturation technique showed the best adaptation. | ||||
