Comparative analysis of apical microleakage for two obturating materials-resilon and gutta-percha with two resin-based sealers

Abstract

Aim: The purpose of this in vitro study was to assess the apical sealing ability of Epiphany/Resilon, AH Plus/gutta-percha and their cross combinations-AH Plus + Resilon and Epiphany+gutta-percha. Materials and Methods: Fifty eight extracted human single-rooted mandibular premolars were used and obturated with different combinations of core material and sealer using lateral compaction technique. The groups were as follows: Group-1: Epiphany + Resilon; Group-2: AH Plus + Gutta-percha; Group-3: AH Plus + Resilon; Group-4: Epiphany + Gutta-percha; Group-5: Negative control group. Apical microleakage was assessed with dye penetration method using stereomicroscope. Statistical analysis was performed using one-way ANOVA followed by post hoc test (Bonferroni test), with significance level set at P 0.05). Conclusions: Resilon + AH Plus showed significantly least amount of microleakage and better apical sealing ability as compared to other groups.
