Measurements of fluorine concentrations in 1320 urine samples collected from 440 children in the city of Maikop showed low levels of fluorine (0.43-0.72 mg) in this group in comparison with the groups receiving prophylactic treatment with optimal safe doses of fluorine with milk (0.88-1.19 mg). Consumption of physiological amounts of fluorine does not lead to its accumulation in the body even after long (up to 5 years) consumption of fluorinated milk. Permanent ratio between the values in the control and prophylactic groups allows less frequent monitoring of fluorine levels: during the first month of prevention and then after 2 and 4 years of prophylaxis with fluorinated milk. Clinical evaluation of anticaries efficiency of fluorinated milk in 920 children aged 6-8 years (309 in the control and 611 in prophylactic groups) showed a significant decrease of caries prevalence (by 12.5-24.5%) and intensity in permanent teeth (by 50.6-56.7% by the CDL index and by 47.6-52.9% by the CDLp index) after 3-5 years of regular consumption of fluorinated milk.
