NCT03761485

Brief Summary

This research aimed to evaluate the risk of dental fluorosis by using an experimental fluoridated acidulated dentifrice compared to conventional dentifrices in two-to-four-year-old children residing in a non fluoridated area by the concentration of fluoride incorporated in childrens' nails, as well as the incorporation of F into the biofilm. Two hundred and ten children participated on this study. They were randomly allocated into three groups differing according to the type of dentifrice used over 12 months: G1:1100 ppm F, pH 4.5; G2:750 ppm F, pH 4.5; G3:1100 ppm F, pH 7.0. The dentifrice was placed on the toothbrush using the "drop" technique. The toenails of the biggest toe were collected in three moments, corresponding to the experimental period of use of the dentifrices (T1, T2 and T3), as well as the biofilm which was collected twice, 5 and 60 minutes after brushing. The nails and biofilm fluoride concentration were analyzed on a specific electrode using the HMDS diffusion facilitated technique.
