Effect of fluoridated milk on caries: 3-year results.

The effect of fluoridated milk consumption has been investigated in a follow-up study of 269 children aged 3-9 years. Children consumed 200 ml of milk daily, fluoridated in the groups 3-5 years with 0.4 mg F-, and in those aged 6-9 years with 0.75 mg F-, for 300 days yearly. The caries data were analyzed with special regard to changes in the DMF values of the permanent first molars, the yearly examination data of the corresponding age groups compared and correlated with the length of fluoridated milk consumption. Statistical analysis of the permanent first molar data showed significant negative correlation between DMF means and length of fluoridated milk consumption in children 5-6 years old at the time of evaluation. The caries reduction after 3 years was 74% and statistically significant (P less than 0.001). In children 7-9 years old the caries reduction of the permanent first molars was less, and statistically not significant. A slight reduction of DMFS mean values in the front teeth of this group could be observed.
