Background: Aim of the study was to evaluate sealing ability of five different root end filling materials by dye penetration method. Materials and Methods: About 100 extracted maxillary central incisors were sectioned at Cementoenamel junction. Access cavities were prepared, instrumented chemo-mechanically, and obturated with laterally condensed gutta-percha and AH Plus sealer. Access cavities were sealed with composite resin. After 3 mm of root resection a 3 mm deep root-end cavity was prepared in each tooth. The teeth were retrofilled with glass ionomer cement (GIC), super-ethoxy benzonic acid (EBA), gray-mineral trioxide aggregate (MTA), white-MTA and biodentine. Three coats of nail varnish were then applied to the whole surface of total length of each root except tip of the root where retrograde filling was applied. All roots were stored in 1% solution of methylene blue for 72 h; after which roots were rinsed under tap water. The teeth were sectioned buccolingually, depth of dye penetration was evaluated under stereomicroscope. Results: The overall results showed no statistically significant difference between two types of MTA and biodentine, but all the three materials are superior to GIC, super-EBA. Conclusion: Both forms of MTA, biodentine provide a better seal than GIC, super-EBA. [ABSTRACT FROM AUTHOR] |
