[Fluoride accumulation of the surface enamel of primary tooth after supervised brushing with a low dose-fluoridated dentifrice].

Abstract

The fluoride accumulation on the surface enamel of primary incisive using a low dosed fluoridated dentifrice (0.085% F) was determined in vivo in comparison with a placebo dentifrice within a longitudinal study. After 12 months supervised brushing the superior incisive of the preschool children used the fluoridated dentifrice show a fluoride concentration of 609 ppm, after 20 months 612 ppm fluoride. The fluoride concentration of the surface enamel of the placebo group was 380 (after 12 months) and 385 ppm fluoride (after 20 months). Presume the optimal caries prevention should not reach by only using the low dosed fluoridated dentifrice.
