  • Title: Push-out bond strength of Resilon/Epiphany and Resilon/Epiphany self-etch to root dentin.

    Journal: J Endod; 2009 Jul; 35(7):1048-50. PubMed ID: 19567332.
    Abstract:
    INTRODUCTION: The present study was designed to investigate the bond strength produced by Epiphany and Epiphany SE to root canal dentin. METHODS: A sample of 36 human upper canines was prepared and assigned to experimental groups (n = 12), designated as group 1, Resilon/Epiphany; group 2, Resilon/Epiphany SE; and group 3, AH Plus/gutta-percha. After the filling procedures, each tooth was prepared for push-out assessment by using root slices of 1-mm thickness. Loading was performed on a universal testing machine at a speed of 0.5 mm/min. One-way analysis of variance and Tukey test for multiple comparisons were used to compare the results among the experimental groups. RESULTS: AH Plus/gutta-percha root fillings showed significantly higher push-out bond strength than both Resilon/Epiphany and Resilon/Epiphany SE (P < .05). There was no significant difference between Epiphany/Resilon and Epiphany SE/Resilon (P > .05). CONCLUSIONS: Under the present in vitro conditions, the adhesiveness quality to root dentin promoted by both Epiphany sealers is compromised even when teeth with simple anatomic features were obturated under well-monitored laboratory conditions.
