We examined the effect of fluoride dentifrice on remineralization of white spot lesions by using quantitative light-induced fluorescence (QLF). The study was done on 129 subjects who had given their informed consent. Sixty-five of the subjects were randomly allocated to a group that brushed with 950 ppm fluoride dentifrice, while 64 others used a dentifrice without fluoride. The subjects brushed their teeth twice a day with their assigned dentifrice for one year. The remineralization effect of the two dentifrices was evaluated by three QLF parameters : mineral loss measured by ΔQ (% mm^2), lesion area measured by S(mm^2), and maximum lesion depth measured by ΔMax (%). These three parameters were recorded at three, six, and twelve month recalls after the baseline examination. We concluded that the fluoride dentifrice improved remineralization of the clinical white spot lesions.
