Endodontic treatment depends on various factors for its success. Chief among them is the need to obtain fluid tight seal at the apical constriction. This is achieved by proper cleaning and shaping together with good obturation of the root canal. Sealers are used along with obturating materials to get adequate seal. Recently, dentin bonding agents have been used along with sealers to achieve proper seal during obturation. This study uses a chemically cured bonding agent along with an epoxy resin sealer along with gutta percha as an obturating agent and the apical sealing efficacy is estimated. This study will point us in the direction of future research in the field of resin chemistry in endodontics.
