Abstract

Aim: The need for this study was to evaluate the effect of Propolis on the shear bond strength of deproteinized dentin to composite compared with that of grape seed extract and sodium ascorbate. Materials and Methods: Group I: dentin surface of specimens pretreated with 5.25% NaOCl for 60 s; Group II: dentin surface of specimens pretreated with 5.25% NaOCl followed by 10% Sodium ascorbate solution for 60 s; Group III: dentin surface of specimens pretreated with 5.25% NaOCl followed by 5% proanthocyanidin solution for 60 s; Group IV: dentin surface of specimens pretreated with 5.25% NaOCl followed by propolis solution for 60 s. The dentin surfaces of all specimens were then coated with self-etch adhesive, Adper Easy One and light cured for 40 s. After adhesive application, nano hybrid composite (Tetric N-Ceram Bulk fill) was placed and light cured for a period of 40 s. Instron universal testing machine was then used to determine the shear bond strength. Results: Statistical analysis showed that 5.25% NaOCl caused significant reduction in the bond strength (P<0.05) which can be reversed by 5% PA, 10% sodium ascorbate and propolis. No statistical significant difference in bond strengths was found between Group II and Group IV. Conclusion: Dentin surface pre-treatment with propolis, proanthocyanidin prior to application of bonding agent over deproteinized dentin significantly increased the bond strength of dentin to composite
