(a) Enamel hardness of the mild lesions group before and after remineralization (mean ± sd; n = 10). Bars with dissimilar letters indicate values that are significantly different from each other (P<0.05).
(b) Enamel hardness of the severe lesions group before and after remineralization (mean ± sd; n = 10). Bars with dissimilar letters indicate values that are significantly different from each other. (P<0.05)
