ABSTRACT
Aim: To assess and compare the effect of resveratrol pretreatment of root dentin on immediate and delayed pushout bond strength (POBS) of fiber postluted using self-adhesive resin cement. Methodology: Postspace was prepared in endodontically treated roots and randomly divided into two groups based on pretreatment rinse before fiber postcementation: Group 1: Distilled water Group 2: 1 mL of 10 mg/mL resveratrol solution for 1 min. Fiber posts were luted using self-adhesive resin cement. Among, two 1 mm slices of the coronal and middle third of root, one slice was subjected to immediate POBS using the universal testing machine and the other slice was subjected to POBS after storing in distilled water for 12 months. Results: Resveratrol pretreatment showed significantly higher immediate POBS with more mixed failure than distilled water group. There was no significant difference in delayed POBS between the distilled water (mean: 7.07 MPa) and resveratrol pretreated group (mean: 8.20 MPa) with predominantly adhesive failure among them. There was significant difference between immediate and delayed POBS value of both the groups. Conclusion: Resveratrol pretreatment can be considered to improve bond strength stability of radicular dentin to self-adhesive resin cement.
