The aim of the present study is to evaluate the effect of 4% TiF4 varnish compared to a commercial 5% NaF varnish on the prevention of dental caries and on the remineralization of non-cavitated enamel carious lesions (white spot lesions) in permanent teeth of children living in fluoridated area. This randomized, longitudinal and blind clinical trial will involve 60 children, 7-12 years old, living in Bauru-SP/Brazil. Two examiners will evaluate the public school children. The children will be selected according to their caries activity (presence of active white spot lesion) and randomly divided into the following treatment groups: G1- 4% TiF4 varnish (2.45 % F-, pH 1, FGM- DentsCare); G2- 5% NaF varnish (2.26% F, pH 5, Duraphat®, Colgate) and G3- control (placebo varnish without fluoride, pH 5, FGM- DentsCare). The treatment will consist of the varnishes applications on all surfaces of permanent teeth, once a week for a period of 4 initial weeks (4 applications/1 month) and one application after 6 and 12 months. Clinical examination will be carried out by two examiners previously calibrated, after inter and intra-examiner agreement (kappa> 0.8), at baseline (before the first application), after 1, 6, 12 and 18 months of the beginning of study. The DMFT index will be applied to analysis the prevention of caries lesions by the application of the treatments. For the analysis of the progression or reversion of white spot lesions will be considered: the criterion of caries activity diagnosis (active versus inactive, Nyvad index) and quantitative fluorescence (”F, ”Q and lesion area) measured using quantitative light-induced fluorescence equipment (QLF). The data will be submitted to appropriate statistical test (parametric or non-parametric), after checking the data normality and homogeneity (p<0.05).
