The typical SEM image of severe lesions of each group. (a) Severe lesions (after demineralization); (b) artificial saliva immersion for 1 month (Control, 1 month); (c) Artificial saliva immersion for 3 months (Control, 3 months); (d) fluoride toothpaste brushing for 1 month (FT, 1 month); (e) fluoride toothpaste brushing for 3 month (FT, 3 months); (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).
