In vivo dissolution rates of enamel in acid in school children were determined to confirm wheather or not the technique could be used to distinguish each individual. In vivo dissolution rates of enamel in acid on the upper left central incisor and the lower left first molar were determined by using 2μl of sodium acetate-hydrochloric acid buffer as described by Nakagaki (1979). The following results were obtained: 1) No clear relationship was observed between the dissolution rate of enamel in acid and the age of the subject. 2) The dissolution rate of enamel in acid in the upper left central incisor was related to that in the lower left first molar within the same individual. 3) The dissolution rate of enamel in acid of an individual was roughly consistent throughout the survey. 4) In general, the results of the dissolution rate of enamel in acid in the lower first molar presented here show distinguishing characteristics for each subject.
