Abstract
The long term quality of the treatment of root canals is reached when a hermetic seal is obtained, but the traditional epoxy-resin sealers tend to demonstrate poor adhesion and poor adaptation. Therefore, it is of interest to compared resin-based sealer made of methacrylate to the existing epoxy-resin and calcium silicate-based sealer in terms of bond strength and marginal adaptation. Ninety human teeth were extracted, obturated, and tested in terms of push-out bond strength and marginal gaps that were assessed by SEM. The experimental sealer of methacrylate resin showed high bond strength and marginal adaptation compared with all groups (p=0.001). Thus, we show that it has a better sealing capacity and may lead to better clinical outcome in endodontic treatment.
