Abstract: The aim of the study is to evaluate the anti- oxidant efficacy of sodium thiosulphate & sodium ascorbate on the recovery of shear bond strength to pulp chamber dentin treated with NaOCI & EDTA. Methodology 40 dentin samples were divided in 4 groups (n=10), Positive control received no treatment, negative control received only irrigation treatment, while the other two experimental groups were treated with their respective anti-oxidant following the irrigation. All the samples were then cured with composite and subjected to SBS test under universal testing machine. Statistical analysis ANOVA & Post hoc tukey were used with P
