Evaluation of the Effect of Different Antioxidants on Resin Bond Strength to Enamel after Bleaching: An Study.

Aim: To compare and evaluate the efficacy of 10% sodium ascorbate (SA) solution, 10% alpha-lipoic acid (ALA) solution, 10% propolis solutions (PLS), and 10% pomegranate peel extract (PPE) solution on the shear bond strength (SBS) between composite resin and bleached enamel after 60 minutes.

Materials And Methods: Ninety extracted teeth were divided into 6 subgroups ( = 15) based on the antioxidant applied: Group I: Bleaching + application of 10% SA solution for 60 minutes. Group II: Bleaching + application of 10% ALA solution for 60 minutes.
