The effect of fluoridated water on DMF scores of first permanent molars in mixed dentitions

New aspects of the problem of estimating the differences in caries activity between groups living in towns with and without a fluoride supplement in the drinking water are considered in this report. Two groups of Finnish children born in 1963, living in two towns, formed the study and control groups. The results show that fluoridated water alone is not sufficient for an effective preventive regimen.
