The present study was undertaken to compare the in vivo dissolution rate of enamel in acid with four other tests in school children as caries activity tests. Cariostat®, buffer capacity of saliva, plaque scores, and snack intake (in addition to the dissolution rates which were reported previously) were examined in 30 school children when they were 7 and 9 years old. The dental caries was examined by the same examiner every six months from the ages of 7 (1981) to 11 (1985).The R.I.D. Indices of the upper central incisors and the upper and lower first molars were calculated by comparing each examination with the base lines at 7 and 9 years of age. The results were analysed using the sum of sensitivity and specificity.The following results were obtained:1) At 7 years of age snack intake was the most useful of the five tests for prediction of the R.I.D. Index of the lower first molars, but after the age of 9 years it was only useful for prediction of the R.I.D. Index of the upper first molars.2) In vivo dissolution rate of the lower left first molar and the plaque score of the upper left central incisor at 7 years of age were useful for prediction of the R.I.D. Index of the lower first molars.3) Cariostat® and the buffer capacity of saliva tended to relate to the R.I.D. Index of all the teeth surveyed.4) in vivo dissolution rate of the upper left incisor and the plaque score of the lower left first molar were meaningless in predicting the R.I.D. Index.5) In conclusion, in vivo dissolution rate of enamel in acid of the lower left first molar was the most useful when we predicted the R.I.D. Index of the lower first molars from a relatively low age. |
