Background: The present study was conducted to assess the micro-tensile bond strength of resin to bleached enamel using different antioxidants. Materials & Methods: This invitro study was conducted on 50 recently extracted permanent premolars. All teeth were sectioned from the root using rotary saw under water irrigation. All specimens were divided into 5 groups of 10 each. Group I was control, in group II, teeth were bleached and restored immediately, in group III samples were bleached and 10% sodium Ascorbate (SA), in group IV samples were bleached and 5% Proanthocyanidin (PA) and in group V samples were bleached and super oxide dismutase (SOD). Micro-tensile bond strength was tested in all samples. Results: The mean microtensile bond strength in group I was 16.2 MPa, in group II was 5.4 MPA, in group III was 15.6, in group IV was 12.8 and in group V was 6.2 MPa. The difference was significant (P< 0.05). Conclusion: Authors found that sodium ascorbate (SA) had tensile strength equal to control group.
