The fluoridation of drinking water is considered a public health measure, which is effective and wide-ranging and also helps controling and preventing dental caries. Monitoring systems of the fluoride levels in public water supplies are essential to adapt the contents at intervals that provide the greatest benefit in relation to the prevention of caries and lower risk of developing dental fluorosis. The purpose of this study was to analyze the levels of fluoride in public water supplies, distributed by 3 cities of water treatment supplies, with and without fluoride located in the northwest of the state of São Paulo. Three points were defined for each source of public municipal water supply. Water samples were collected monthly and analyzed in the Research Laboratory of the Center for Public Health (NEPESCO), Graduate Program in Public Health, School of Dentistry of Araçatuba (UNESP). During a period of 88 months of 2974 samples, the levels of fluoride in 65.23% (n = 970) had levels of fluoride between 0.55 and 0.84 mg F / L,; 13.38% (n = 199) had a content below 0.55 mg F / L and 21.38% (n = 318) had fluoride levels above 0.84 mg F / L. Among the municipalities that did not add fluoride, one of the control samples had shown values less than 0.55 mg F / L and the other with values above 0.84 mg F / L, providing the maximum benefit, related to dental caries and it also had a moderate cost as high as dental fluorosis. It stands out that it's necessary to analyze the water distribution networks and develop procedures for dilution and mixing to improve the use of natural fluoride in deepwater wells, aiming to achieve the desired level of fluoride. It was found that in cities that added artificially ion in water, the process was continuous and within the recommended parameters, considering then...
