“…In Cachoeiras do Sul, RS, in Piracicaba, SP, and in a study of 29 Brazilian cities 63.4% 20 , 85% 21 and 53.5% 22 of the samples, respectively, were within acceptable levels. In contrast, in Ponta Grossa, PR, two-thirds of the samples were outside the ideal level; 23 in the state of Piauí, only 4.3% of samples were within the optimal range, 24 and 53.6% of the samples from the island of São Luis, MA, were less than the optimal range, 25 compromising the benefits of the fluoridation process. A survey conducted in the database of the Laboratory of Oral Biochemistry, Piracicaba Dental School, UNICAMP, showed that 40% of the samples References collected were outside the acceptable standards.…”

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.

“…This temporal increase in the proportion of water samples with appropriate fluoride levels demonstrates the importance of longitudinal studies and the effectiveness of constant monitoring, which facilitates the operational control of water fluoridation procedures and improves the quality of public water supplies. [19][20][21][22][23] In another study of eight cities in northwestern São Paulo State conducted during a 36-month period from November 2004 to October 2007, Saliba et al 24 found a higher proportion (77.4%) of water samples with fluoride levels within recommended parameters. However, it should be noted that these eight cities used a single water source.…”

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

“…Todos os estudos citados mostraram variação na adequação da concentração de flúor ao longo do tempo e dos pontos de coleta, e elevada proporção de concentrações consideradas inadequadas em sua maioria 12,14,15,17,21,22,23,24,26 . Evidenciam-se, assim, dificuldades operacionais na manutenção adequada da concentração ótima de flúor nas águas de abastecimento público no contexto brasileiro, justificando a necessidade e importância da instituição e manutenção de sistema de vigilância sanitária da fluoretação das águas de abastecimento públi-co. Em acréscimo, problemas legais contribuem para tal situação.…”

“…Entre elas: as normas do Laboratório de Vigilância do Flúor da UNIVALI, que foram utilizadas em Chapecó e também em outros estudos 23,26 ; a Portaria nº. 518 30 , que estabelece um ponto de coleta para cada 10 mil habitantes 18 ; e a distribuição por região administrativa e geográfica 12,15,16,17,27 . Ressalta-se que para o cálculo de tamanho de amostra deve-se avaliar a variabilidade do fenômeno, considerando a interferência de fatores como o número de estações de tratamento e a densidade populacional, não apenas o porte populacional.…”

“…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.…”
