the recorded in depth profiles of f concentration show that , after 14 days of remineralization , 1 ) neither the acquired f levels nor the f distributions are greatly dependent on whether fluoridation is from naf , mfp or mixtures , 2 ) the f distribution shape is not strongly influenced by a 3-month storage followed by remineralization , 3 ) the penetration of f beyond the lesion is generally deeper from naf than from mfp , and 4 ) the effect of long storage on penetration depth is mainly noticeable for mfp-treated specimens .
