Evaluation of the apical sealing ability and adaptation to the dentin of two resin-based Sealers: An in vitro study

AIM: To quantitatively evaluate the apical sealing ability and adaptation of two resin-based sealers to dentin. MATERIALS AND METHODS: Fifty freshly extracted mandibular first premolars were taken and sectioned at the cemento-enamel junction. Thirty teeth were subjected to a leakage study by the res...

description AIM: To quantitatively evaluate the apical sealing ability and adaptation of two resin-based sealers to dentin. MATERIALS AND METHODS: Fifty freshly extracted mandibular first premolars were taken and sectioned at the cemento-enamel junction. Thirty teeth were subjected to a leakage study by the resin infiltration method with two groups of 10 teeth each. Group I teeth were obturated with methacrylate resin-based sealer (EnoRez) and Group II teeth were obturated with epoxy resin-based sealer (AH Plus). The remaining 10 teeth were used as controls (positive and negative of five teeth each). Twenty teeth were divided into two groups and obturated as in the leakage study and subjected to a scanning electronic microscopy (SEM) analysis for adaptation and resin depth penetration. RESULTS: Both the sealers produced apical leakage to a certain extent. The adaptation and resin sealer penetration in the coronal and middle thirds was better than in the apical third of the root canal under SEM observation. The hybridized resin sealer tags in the coronal and middle thirds of Group I were much longer than that shown by Group II. CONCLUSION: We conclude that the physical integrity of the sealer matrix may also be important in providing resistance to leakage.
