Comparative evaluation of the apical sealing ability and adaptation to dentine of three resin-based sealers: An in vitro study

OBJECTIVE: To evaluate the apical sealing ability and adaptation of three resin-based sealers to the dentine. MATERIALS AND METHODS: A total of 66 recently extracted human maxillary anterior teeth were subjected for the study. The teeth were prepared and obturated with gutta-percha by a lateral condensation using AH Plus, Endorez and Epiphany sealers. Fifteen teeth from each group were used for the apical leakage test and the remaining five teeth from each group were used for examination under the scanning electron microscope. Data were analyzed using one-way ANOVA and the Student Newman-Keuls test. RESULTS: Epiphany sealer showed better sealing ability and adaptation to dentine. CONCLUSION: The Epiphany sealer has a better apical sealing ability and adaptation to dentine than the AH Plus and Endorez sealers.
