Effect of fluoride on mineral loss in the intra-oral cariogenicity test

The loss of Ca and P was determined in different layers of enamel slabs after an Intra-Oral Cariogenicity Test with 3% sucrose in the presence and absence of F-. The mineral loss could be inhibited largely by 0.1% F-. A direct relationship between indenter penetration change and mineral loss was demonstrated in the absence of F-.
