Background: This study was done to evaluate remineralizing potential of bioactive glasses (BAGs) and amorphous calcium phosphate-casein phosphopeptide (ACP-CPP) on early enamel lesion. Materials and Methods: Twenty freshly extracted mandibular premolars were sectioned sagittally. The buccal half was impregnated in acrylic resin blocks and treated with 37% phosphoric acid in liquid form, to demineralize enamel surface to simulate early enamel lesion. The samples were divided into two groups. The samples in Group I were treated with ACP-CPP (GC Tooth Mousse) and in Group II with BAG (Sensodyne Repair and Protect) and stored in saliva to prevent dehydration. The samples were tested for microhardness. The data obtained was analyzed using ANOVA post hoc multiple comparison and independent sample t- test and presented as a mean and standard deviation. Results: All the samples showed a decrease in the microhardness after demineralization. After application of remineralizing agents, Group II showed a highly significant increase in the microhardness (P < 0.05) after 10 days, while Group I showed a significant increase in microhardness after 15 days (P < 0.05). Conclusion: Both the remineralizing agents tested in this study can be considered effective in repair and prevention of demineralization. BAG showed better results initially, but eventually both have similar remineralizing potential.
