| Abstract | ||||
| ABSTRACT Background: Endodontic surgery becomes a practical choice when non-surgical interventions are ineffective or are not expected to yield improved results. Limited access and technical challenges may prevent the implementation of controlled retrograde procedures in certain teeth. Aim of the study: The objective was to compare bacterial microleakage of root end resected teeth after orthograde obturation using a single cone technique with a bioceramic sealer versus MTA retrofilling. Materials and Methods: Thirty human extracted maxillary incisors were prepared and divided randomly into three groups. In group1, the canals were filled using the single cone technique with bioceramic sealer, followed by root resection 3 mm from the apex. Group 2 received standard retrograde ultrasonic preparation and retrograde obturation with mineral trioxide aggregate (MTA) and group 3 negative control. Subsequently, the roots were placed in a sterile experimental model and filled coronally with E. faecalis bacterial suspension for 30 days. Turbidity and the time taken for turbidity in the broth were analyzed to assess bacterial microleakage from the canal. Results: The study revealed that there was no statistically significant difference in bacterial microleakage observed between the two test groups. Conclusion: Performing root end resection following a single cone technique obturation, along with a bioceramic sealer, may offer a favorable alternative approach when compared to the established gold standard MTA retrograde obturation. | ||||
