Effect of Daily Applications of Sodium Monofluorophosphate Solution on Caries Rate in Children

Abstract
The daily application of a 6% solution of sodium-monofluorophosphate to the teeth of children for a period of 9 mo. resulted in a 30.9% reduction of their R.I.D. and a 25.5% reduction of their [DELTA]DFS. After 14 mo., the R.I.D. was 39.4% lower than in the control group; and the [DELTA]DFS was 42.1% lower. There was 41% more reversed or remineralized lesions after 9 mo. and 66% more than those in the control group after 14 mo. This test was conducted in an area supplied with water containing 1 ppm fluoride added as NaF.
