| 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. |
