The aim of the present study was to test the fluoride contents of infant formulas and market milk in Turkey. Fifteen formulas and nine market milks were prepared according to manufacturers' instructions with deionized water. Fluoride contents were analyzed with a spectrophotometer (CADAS 50S) and results were obtained as ppm (microgF/ml). Mean fluoride content of the formulas was 0.101 ppm F and of the milks was 0.08 ppm F. Formulas reconstituted with water containing < 0.3 ppm F do not provide a daily fluoride intake at any age. To decrease dental caries among children in Turkey, fluoride supplements could be prescribed at minimal dosages according to the ADA fluoride schedule.
