[Alimentary intake of fluorides of artificially fed infants and effect on enamel tissue].

The dietary daily intake of fluorides in the first six months of lifetime has to be taken into special consideration. The slightly toxicological permissible limits of the fluorides can cause mottled enamels. The safe amount of the dietary daily intake for babies ranged up to 0.5 mg. By use of the food-stuff "MANASAN" prepared with fluoridated drinking water the daily intake increased up to 1.01 mg F-. In 150 7-8-years old children which in the first 4 month of lifetime got "MANASAN" prepared with fluoridated drinking water we found in 40% of the children mottled enamels, the fluorosis index scores (defined by DEAN) 0.4 respectively. The caries prevalence was by 0.85 DMF surfacer index.
