“…Thus, the operational control of water fluoridation was inadequate in terms of maintaining fluoride levels in the public water supply. 25 These findings indicate that the external control of water fluoridation may safely and reliably prevent large variations in fluoride levels in public water supplies. Only 3.4% of our samples had fluoride levels > 1.2 mg F/L, and municipalities promptly corrected such fluoride overdosing to avoid the risk of dental fluorosis.…”

“…In a study that monitored municipal control of fluoride levels in Niteroi, RJ, Brazil for 1 year, Maia et al 25 found that treated water showed a wide variation in fluoride concentration (0.03-1.49 mg F/L) and 96% of samples had inadequate concentrations. Thus, the operational control of water fluoridation was inadequate in terms of maintaining fluoride levels in the public water supply.…”

The fluoridation of public water supplies is considered the most efficient public health measure for dental caries prevention. However, fluoride levels in the public water supply must be kept constant and adequate for the population to gain preventive benefit. The aim of this study was to analyze fluoride levels in the public water supply of 29 Brazilian municipalities during a 48-month period from November 2004 to October 2008. Three collection sites were defined for each source of municipal public water supply. Water samples were collected monthly and analyzed at the Research Laboratory of the Nucleus for Public Health (NEPESCO), Public Health Postgraduate Program, Araçatuba Dental School (UNESP). Of the 6862 samples analyzed, the fluoride levels of 53.5% (n = 3671) were within the recommended parameters, those of 30.4% (n = 2084) were below these parameters, and those of 16.1% (n = 1107) were above recommended values. Samples from the same collection site showed temporal variability in fluoride levels. Variation was also observed among samples from collection sites with different sources within the same municipality. Although 53.5% of the samples contained the recommended fluoride levels, these findings reinforce the importance of monitoring to minimize the risk of dental fluorosis and to achieve the maximum benefit in the prevention of dental caries

“…Todavia, estabeleceu-se um maior número de pontos de coleta, no sentido de proporcionar mais informações que contribuíssem para os valores finais. Na Tabela 1, constata-se que a maioria das amostras não atingiu a faixa aceitável (0,60 a 20 apresenta resultado semelhante em Niterói, Rio de Janeiro. Falhas do controle da fluoretação tem sido verificada por estudos tanto no Nordeste como em outras regiões do país 21,22,23,24,25 .…”

“…635 11 , a concentração ótima de flúor para o município está determinada em 0,8ppm, com limite mínimo de 0,7ppm (variação de 0,1ppm) e limite máximo de 1,0ppm (variação de 0,2ppm). Dessa forma, considera-se adequada a concentração entre 0,7ppm e 1,0ppm, inadequada baixa quando < 0,7ppm e inadequada alta quando > 1,0ppm; b) critério II: adotado pela maioria dos estudos de heterocontrole publicados no Brasil 10,12,13,14,15,16,17 , segundo a concentração ótima determinada para a maioria das localidades brasileiras (Portaria nº. 635 11 ) que admitem variação na concentração ótima de 0,1ppm para os limites inferior e superior.…”
