Background: Endodontic leakage research focus mainly on the quality of the apical seal of the root canal system and the newly introduced resilon/epiphany system claim to be superior to Gutta-percha in respect to obturation procedure. The aim of this study is to evaluate the root canal obturation completed by resilon/epiphany system.
Materials and methods: A total of 42 teeth were selected and were divided into four groups. Two experimental groups consisted of 15 teeth each and positive control group consisted of eight teeth and negative control group consisted of four teeth. In the experimental groups, Group 1 was obturated with resilon/epiphany system and Group 2 was obturated with Gutta-percha and endofil sealer by lateral condensation technique. The teeth were then immersed in Methelene blue solution and were split longitudinally to access the amount of dye penetrated in the canal. The specimens were viewed under scanning electron microscope to evaluate the adhesion of the obturating material to the root canal walls. Data was subjected to statistical analysis by Analysis of Variance and Bonferroni multiple comparison test at 1% level of significance.
Results: The resilon/epiphany system showed better adaptation to the root canal walls, but the difference in dye penetration was not statistically significant when compared to specimens obturated with Gutta-percha and endofil sealer.
Conclusion: Although, there was no statistically significant difference between the groups, but resilon/epiphany system showed better adaptation to the root canal walls.
