Abstract: Aim: To evaluate the effects of Hydroxytyrosol on the pull out bond strength of fiber reinforced post to Sodium Hypochlorite (NaOCl) treated root dentin. Materials and method: Forty single?rooted extracted human teeth were randomly divided into two groups based on the final irrigation protocol: Group 1 (15% Hydroxytyrosol) and Group 2 (saline). The canals were cleaned, shaped, irrigated thoroughly using 5.25% Sodium hypochlorite and obturated with gutta?percha and AH Plus sealer. Post space was then prepared and the post spaces were flushed with the respective solutions. Fiber posts were luted in the post spaces of all the specimens using dual cure resin luting cement. All the prepared specimens were then mounted upright on acrylic resin blocks. After 24 hours, pull out bond strength test was carried out using universal testing machine. The data were statistically analyzed using Mann Whitney U test (P < 0.05). Results: 5.25% NaOCl significantly decreased the bond strength of fiber post to dentin (P < 0.05). 15% hydroxytyrosol was capable of reversing the compromised pull out bond stregth of fiber post to NaOCl?treated root dentin. Conclusion: Rinsing the post space with Hydroxytyrosol prior to bonding increased the pull out bond strength of fiber reinforced post to NaOCl treated intraradicular dentin.
