This study analyzed the effects of a fluoride (F) varnish supplemented with sodium trimetaphosphate (TMP) on the remineralization of caries-like lesions in situ. Twelve subjects used palatal devices with demineralized enamel discs for 3 days, following a double-blind, crossover protocol. The volunteers were randomly divided into 3 study groups according to the varnishes used: Placebo (no F or TMP), 5% NaF and 5% NaF NaF / 5% TMP. Two disks were removed from the palatal device 6 hours after the application of varnishes, to determine the loosely bound fluoride (CaF2), and strongly bonded to the enamel. In the other two disks were determined the percentage of surface hardness recovery (% SHR), the integrated area of the lesion (ΔKHN) and F weakly and strongly bonded to the enamel. The results were submitted to ANOVA and Student-Newman-Keuls (p <0.05). Varnish 5% NaF / 5% TMP promoted the highest % SHR and less ΔKHN when compared to other groups, with significant differences between all varnishes. The concentrations of CaF2 and F strongly bonded to enamel were significantly higher for the varnish 5% NaF, followed by 5% NaF/ 5% TMP and placebo. It can be concluded that the remineralizing effect varnish containing 5% NaF is significantly enhanced when combined with TMP
