The typical SEM image of mild lesions of each group. (a) Sound enamel (before demineralization); (b) mild lesions (after demineralization); (c) artificial saliva immersion for 1 month (Control, 1 month); (d) artificial saliva immersion for 3 months (Control, 3 months); (e) fluoride toothpaste brushing for 1 month and 3 months (FT, 1 m; FT, 3 m); (f) combined use of fluoride varnish plus fluoride toothpaste for 1 month (FV + FT, 1 month); (g) combined use of fluoride varnish plus fluoride toothpaste for 3 months (FV + FT, 3 months); (h) Combined use of CPP-ACP plus fluoride toothpaste for 1 month (CPP-ACP + FT, 1 month); (i) combined use of CPP-ACP plus fluoride toothpaste for 3 months (CPP-ACP + FT, 3 months).
