“…These data suggest that is more difficult control the fluoridation from AWs than WTPs, in agreement with the data from other studies conducted in Capão Bonito 27 and Araçatuba, SP. 28 However, in terms of the risk of fluorosis, the findings showed that only one sample from one month was within the range of high risk of fluorosis for water from AWs (14% in September) and from the WTP (5% in March).…”

Fluoride concentrations in the water of Maringá, Brazil, considering the benefit/risk balance of caries and fluorosis Abstract: Current Brazilian law regarding water fluoridation classification is dichotomous with respect to the risks of and benefits for oral diseases, and fluoride (F) concentrations less than 0.6 or above 0.8 mg F/L are considered outside the normal limits. Thus, the law does not consider that both caries and fluorosis are dependent on the dosage and duration of fluoride exposure because they are both chronic diseases. Therefore, this study evaluated the quality of water fluoridation in Maringá, PR, Brazil, considering a new classification for the concentration of F in water the supply, based on the anticaries benefit and risk of fluorosis (CECOL/USP, 2011). Water samples (n = 325) were collected monthly over one year from 28 distribution water networks: 20 from treatment plants and 8 from artesian wells. F concentrations were determined using a specific ion electrode. The average F concentration was 0.77 mg F/L (ppm F), ranging from 0.44 to 1.22 mg F/L. Considering all of the water samples analyzed, 83.7% of them presented from 0.55 to 0.84 mg F/L, and according to the new classification used, they would provide maximum anticaries benefit with a low risk of fluorosis. This percentage was lower (75.4%) in the water samples supplied from artesian wells than from those distributed by the treatment plant (86%). In conclusion, based on the new classification of water F concentrations, the quality of water fluoridation in Maringá is adequate and is within the range of the best balance between risk and benefit.

“…Several studies recommend Oral Health Surveillance (Narvai, 2000;Zimmer et al, 2003;Lima et al, 2004;Moimaz et al, 2015;Frazão et al, 2018) for an external control besides operational control, thus providing the achievement of reliable results regarding fluoride levels (Ramires and Buzalaf, 2007;CECOL, 2011;Frazão et al, 2018), enhancing this public health strategy, promoting anti-carie coverage, and preventing fluorosis. Fluoridation control by institutions not involved directly in its operation is an essential condition to preserve the quality of the process and for information credibility (Lima et al, 2004;Olivati et al, 2011).…”

The surveillance of the concentration of fluoride in the public water supply aims to ensure the balance between the benefits (carie prevention) and risk (dental fluorosis) of water fluoridation programs. The aim of this study was to check the accuracy of two analytical methods for monitoring the concentration of fluoride in the public water supply of a Brazilian city. The STROBE checklist was used to aid the conduction of this study and report the results. It was an analytical, observational, and prospective study using the water supply of Uberlândia, MG, Brazil. We collected 126 water samples at 21 sites for six consecutive months and analyzed them using the fluoride ion selective electrode (F-ISE) method and colorimetry with SPADNS. The statistical analysis was performed descriptively and then the ANOVA and Student t-test for paired samples were applied. The results showed that the F-ISE method had a lower coefficient of variation (12.3%) than the SPADNS method (57.4%). There was no significant variation of the fluoride concentration in the water through the supply network evaluated either by F-ISE as SPADNS. We concluded that the electrometric method should be the first choice for use by laboratories that monitor fluoride concentration in the public supply water.

“…Em relação à concentração do fluoreto, considerar que esse parâmetro possui elevada estabilidade (Prado et al 1992), pode ajudar a reduzir o número de pontos de coleta de amostras com importante implicação para os custos da iniciativa conforme literatura especializada (Narvai 2001;Ely et al 2002;Lima et al 2004;Lodi et al 2006;Toassi et al 2007;Olivati et al 2011).…”

A obra, composta de doze capítulos, apresenta-se à comunidade científica, notadamente aos segmentos de Saúde Coletiva e de Odontologia, como uma investigação na qual participaram 33 pesquisadores de várias universidades brasileiras. A pesquisa "Cobertura e Vigilância da Fluoretação da Água de Abastecimento Público no Brasil (Projeto Vigifluor)" foi desenvolvida no âmbito do Centro Colaborador em Vigilância da Saúde Bucal do Ministério da Saúde - CECOL/USP, uma iniciativa de cultura e extensão da Universidade de São Paulo na esfera da Faculdade de Saúde Pública, visando mapear a cobertura da fluoretação das águas de abastecimento público, de 2010 a 2015, nos 614 municípios brasileiros com mais de 50 mil habitantes. Nessa publicação são apresentados aspectos teóricos relativos a essa tecnologia de saúde pública e os resultados detalhados desse esforço investigativo.
