Introduction: During 1 year, the Núcleo de Ciências Químicas e Bromatológicas do Centro de Laboratório Regional do Instituto Adolfo Lutz de Ribeirão Preto (SP, Brasil) has increased the number of public water supply samples analyzed for fluoride concentration in relation to what is usually requested by 88 Municipal Sanitary Surveillance of Northeast State of São Paulo (Brazil). Objective: To verify if fluoridation indicators values will vary when increasing the number of samples analyzed and to assess the quality of fluoridation in the region. Method: Fluoride was determined by ion chromatography in samples collected by Sanitary Surveillances. Results: Indicators values of fluoridation obtained in the two sampling (Sanitary Surveillances and expanded) were similar for most cases. The mapping indicated a greater number of municipalities with values greater than 80% in Regional Departments of Health of Barretos and Franca, while in Araraquara and Ribeirão Preto prevail indicator values lower than 40%. Conclusions: Investment and technical assistance are insufficient to increase the values above 80% in municipalities with small populations. For the cases in which the values are smaller than 40% an approach based on the similarity between municipalities is suggested to increase these values.Downloads
