| Abstract;The purpose of this present study was to clarify the changes of fluoride concentrations in the surface enamel of immature young permanent teeth with post-eruptive maturation. The surface enamel of the lower central incisors partially erupted and completely erupted were used to determine the fluoride concentrations, acid solubilitios and Ca/P. The following results were obtained; 1. The fluoride concentrations of the surface enamel decreased from the outer surface of the enamel toward the inner parts. 2. The fluoride concentrations of the surface enamel in completely erupted tooth were significantly higher than those in partially erupted at the layer depth of 1-10.MU.m. (p<0.01-0.05) 3. The mean Ca/P (w/w) values ranged from 2.01-2.10 invariably. 4. The acid solubilities of the surface enamel in completely erupted teeth were significantly lower than in partially erupted teeth.
