Abstract


Introduction: Root-end filling materials are used to provide an apical seal that prevents the movement of bacteria and bacterial products from the root canal system into the periapical tissues. The present study was conducted to evaluate sealing ability and marginal adaptation of four different root-end filling materials by dye penetration method and scanning electron microscopy (SEM). Materials and Methods: Eighty single-rooted human maxillary central incisors were sectioned at cementoenamel junction, prepared, obturated, and resected and 3 mm deep root-end cavity was prepared. Teeth were retrofilled with Biodentine, mineral trioxide aggregate (MTA), MTA Plus, and glass ionomer cement (GIC). Sealing ability was checked by dye penetration method under stereomicroscope. Teeth were split longitudinally and the extent of gap was measured linearly, using SEM to evaluate marginal adaptation. The data were analyzed using SPSS software by Kruskal–Wallis H test and Mann–Whitney U-test. Results: Biodentine showed better sealing ability and MTA Plus showed better marginal adaptation compared to all other materials. Conclusion: Within the limitations of this study, Biodentine provided better seal and MTA Plus exhibited better marginal adaptation than MTA and GIC when used as retrofilling material.
