Bond strength of Resilon/Epiphany compared with Gutta-percha and sealers Sealer 26 and Endo Fill

摘要

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 1.5mm. 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 2mm-thick cross-sections were obtained from each tooth (n=15) and subjected to a push-out test (1mmmin -1). The means (MPa) were compared using anova /Newman-Keuls tests. There were no statistically significant differences between Group I and Group II (P0.01). Both bond strengths were significantly higher than that of Group III (P0.01). 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.
