Summary

This study aims to assess the overall effect of pH and fluoride concentration of liquid dentifrices in the control of children dental caries of a fluoridated area, through visual inspection and the quantitative light-induced fluorescence (QLF) method. Toenail F concentration of a subsample of the children enrolled will be evaluated, in order to assess F bioavailability from these formulations and the evaluation of the concentration of fluoride incorporated into the biofilm will be done 6 months after initiation of the dentifrices use.
