NCT00723515

Brief Summary

The study hypothesis is the difference in therapeutic effect of two varnish formulations (G1 = NaF, 2.26%F, G2 = NaF, 2.71% F + CaF2). These products are commercially available in the Brazilian and international market and they are used for dental caries as white spot lesions control.
