Evaluation of Apical Sealing Ability of Resilon

Background: This study was conducted to evaluate the efficiency of Resilon in achieving an adequate apical seal, and to compare it with Gutta-percha. Materials and Methods: Sixty single rooted human teeth were selected and decoronated at the cement-enamel junction. The teeth were sectioned such that 14 mm of the root length remained. Working length was established, and cleaning and shaping were carried out using hand files. The canals were enlarged to size 40. Any tooth requiring further enlargement, were discarded. Canals were irrigated using 5.25% NaOCl, and smear layer was removed using 17% ethylenediaminetetraacetic acid. Teeth were divided into four groups. Group 1 consisted of 15 samples obturated with laterally condensed Resilon using Epiphany as the sealer. Group 2 consisted of 15 samples obturated with laterally condensed Gutta-percha using AH plus as the sealer. Group 3 and Group 4 served as the positive and negative control, respectively. Teeth were then studied using dye penetration method followed by clearing technique. The cleared teeth were then studied under the microscope to measure the extent of leakage, and the results were statistically analyzed. Results: The apical leakage seen with Resilon and Epiphany system was significantly less when compared with Gutta-percha and AH plus sealer. Conclusion: Resilon and Epiphany system achieved a superior apical seal when compared with Gutta-percha. However, further studies have been conducted to evaluate its clinical performance.
