title: Bond strength of Resilon/Epiphany compared with Gutta-percha and sealers Sealer 26 and Endo Fill.
abstract: This study evaluated the bond strength of Epiphany(®)/Resilon(®) to radicular dentine and compared this with that of Gutta-percha sealed with Sealer 26 and also Endo Fill(®). Fifteen human single-rooted extracted teeth had their root canals enlarged to a standardised internal root diameter of 1.5 mm. The teeth were filled with: Group I--Epiphany(®)/Resilon(®) cones, Group II--Sealer 26(®)/Gutta-percha cones and Group III--Endo Fill(®)/Gutta-percha cones. Three 2 mm-thick cross-sections were obtained from each tooth (n = 15) and subjected to a push-out test (1 mm min(-1)). The means (MPa) were compared using anova /Newman-Keuls tests. There were no statistically significant differences between Group I and Group II (P > 0.01). Both bond strengths were significantly higher than that of Group III (P < 0.01). The root canal filling system Epiphany(®)/Resilon(®) showed bond strength similar to that of Sealer 26(®)/Gutta-percha. Both were higher than that of Endo Fill(®)/Gutta-percha.
