O trabalho visa avaliar a efetividade da fluoretação da água de consumo nos sistemas da microrregião de Araçatuba (SP) por meio de 5.157 análises de flúor realizadas no período de 2001 a 2005. Os dados foram analisados com relação ao tipo de manancial e à estrutura dos sistemas, representada pela população dos municípios e tipo de administração. Verificou-se que 51,6% das amostras não atenderam ao padrão de fluoretação e que o maior percentual de atendimento ocorreu nos sistemas operados pela Sabesp (69%), seguidos pelos Grandes (52,1%), estatisticamente semelhantes aos Médios (51,4%), e pelos Pequenos (28%). Sistemas que utilizam água superficial apresentaram desempenho estatisticamente superior ao padrão (60%) em relação aos que utilizam água subterrânea (42,9%). Dentre os últimos, os que exploram o aquífero Guarani foram superiores (52,3%) aos outros (46,6%).; This paper focuses on the drinking-water fluoridation process in Araçatuba region water supply systems by means of 5.157 fluoride concentration data from 2001 to 2005. These data were studied based on the water source, the administration and the structure of the water supply system, according to the population of the county and the type of management. Almost half of samples did not comply the fluoridation standard and the higher compliance was verified in the water supply systems operated by Sabesp (69%)...

No Brasil existem dificuldades para o controle da dosagem correta do flúor na água de abastecimento, ainda que sua incorporação represente um método seguro, econômico, eficaz e eficiente para reduzir os níveis de cárie dentária na população. O flúor presente constantemente na água ingerida participa dos ciclos de desmineralização e remineralização do esmalte dentário, atuando de forma terapêutica e preventiva, tendo sido atribuída à fluoretação das águas uma redução de 30 a 60% na incidência da cárie dentária. Para alcançar os efeitos preventivos, os teores adequados precisam ser mantidos permanentemente, pois a interrupção temporária ou definitiva e teores de flúor abaixo do recomendado acarretam a perda do benefício pela população. Para teores acima do recomendado, corremos o risco de desenvolver a fluorose dentária nas crianças cujos dentes estejam em formação. Este estudo propõe, através de uma metodologia qualitativa, usando como estratégia investigativa a entrevista semi-estruturada e a análise documental, conhecer como o município de Ribeirão Preto realiza o monitoramento da fluoretação das águas de abastecimento público, contextualizando-o com as políticas públicas de saúde...

Introdução - A cárie dentária representa, ainda, em termos de saúde bucal, o principal agravo em saúde pública no Brasil. A fluoretação da água de abastecimento público tem participação comprovada na redução dos índices de prevalência, tendo sido considerada uma das dez grandes conquistas da saúde pública do século XX. Regulamentada no país em 1974, a medida teve acentuada expansão nos anos 80, sobretudo nas regiões de maior desenvolvimento sócio-econômico, como o Estado de São Paulo. A ampliação da cobertura da fluoretação aos municípios com sistemas de tratamento de água é uma das prioridades da política nacional de saúde bucal. Objetivos - Identificar, reunir e sistematizar informações disponíveis sobre a cobertura da fluoretação e descrever sua evolução no Estado de São Paulo, no período de 1956 a 2009. Material e Método - Estudo descritivo, com utilização de dados secundários, tendo como unidade de análise os municípios do Estado de São Paulo, descrevendo um histórico da cobertura desde a instituição da medida. A apresentação dos dados é feita por meio de tabelas, gráficos e mapas temáticos, produzidos a partir de sistemas de informações geográficas. Resultados - A cobertura da fluoretação no Estado de São Paulo evoluiu de apenas um para 546 municípios...

Introdução - A política de fluoretação das águas de abastecimento público requer aplicação contínua desta medida em níveis adequados de flúor. O controle operacional é realizado pelas empresas de saneamento ao adicionar flúor às águas, cuja medida deve ser complementada pela ação dos sistemas de vigilância segundo o princípio do heterocontrole. Sistemas de vigilância lidam com informações de interesse público, nos marcos legais desenvolvidos pelos Estados. No mundo contemporâneo, tais marcos implicam contemplar o direito de acesso à informação. Objetivo - Descrever o sistema de vigilância da fluoretação da água no município de São Paulo, no período 1990-2011. Método - Pesquisa baseada em dados secundários disponibilizados pela Secretaria Municipal de Saúde de São Paulo, no período 1990-2011. Os teores de fluoreto nas amostras foram classificados segundo as dimensões de risco e benefício para fluorose e cárie dentária, avaliados concomitantemente.

Objective: To determine the prevalence and severity of caries in 3-12-year-old children in three districts of the city of Araraquara, Design: An epidemiological survey was carried out by trained and calibrated examiners in 1995 and 1996, using the WHO diagnostic criteria. Setting: Two districts, Araraquara and Vila Xavier had been fluoridated since 1963 and one, Gavião Peixoto, since 1994. Subjects: The study included 1,191 children from Araraquara, 653 from Vila Xavier and 652 from Gavião Peixoto. Outcome measures: Prevalence of caries, dmft, dmfs, DMFT and DMFS indices. Results: Results showed moderate caries experience in all three districts. Differences between districts in relation to fluoridation history were particularly obvious in primary teeth. In 3-4-year-old children, one third of those in Araraquara and Vila Xavier had some caries experience compared to 58% in Gavião Peixoto. In permanent teeth, 20% or less of the mean DMFT was made up of untreated decay in Araraquara and Vila Xavier whereas in Gaviao Peixoto it made up between 50 and 57% of values in 7-12-year-old children. Conclusions: The prevalence and severity of caries was lower in dentitions of children from the districts fluoridated since 1963. Improvements are likely in the future in Gaviao Peixoto as the benefit of fluoridation continues but additional means of promoting oral health are needed in all three districts.

Fluoride levels in the public water supplies of 40 Brazilian cities were analyzed and classified on the basis of risk/benefit balance. Samples were collected monthly over a seven-year period from three sites for each water supply source. The samples were analyzed in duplicate in the laboratory of the Center for Research in Public Health - UNESP using an ion analyzer coupled to a fluoride-specific electrode. A total of 19,533 samples were analyzed, of which 18,847 were artificially fluoridated and 686 were not artificially fluoridated. In samples from cities performing water fluoridation, 51.57% (n=9,720) had fluoride levels in the range of 0.55 to 0.84 mg F/L; 30.53% (n=5,754) were below 0.55 mg F/L and 17.90% (n=3,373) were above 0.84 mg F/L (maximum concentration=6.96 mg F/L). Most of the cities performing fluoridation that had a majority of samples with fluoride levels above the recommended parameter had deep wells and more than one source of water supply. There was some variability in the fluoride levels of samples from the same site and between collection sites in the same city. The majority of samples from cities performing fluoridation had fluoride levels within the range that provides the best combination of risks and benefits...

This paper reviews the rationale, context and support for water fluoridation in Australia, and examines current Australian evidence concerning the caries-preventive effects of fluoridation and trends in dental fluorosis. Nearly two thirds of the Australian population resides in an area with adjusted levels of fluoride in the water supply. However, public knowledge about fluoridation is poor and opinion polls demonstrate declining support for fluoridation. In the press and scientific literature there has been questioning of fluoridation, although the most recent Australian review reasserted its safety and effectiveness. Results from Australian oral epidemiological studies consistently support the accumulated evidence on the effectiveness of water fluoridation. This includes recent evidence that lifetime exposure to fluoridation is associated with average reductions of 2.0 dmfs and between 0.12 and 0.30 DMFS per child compared with non-exposed children. Water fluoridation has been found to reduce socio-economic inequalities in caries, reducing the differential between high and low socio-economic status groups by approximately 1.0 dmfs and 0.2 DMFS per child. The prevalence of dental fluorosis may have increased, prompting renewed consideration of overall exposure to fluorides. Action is currently being taken to reduce the exposure to discretionary fluoride among pre-school children as part of a targeted approach to adjusting the benefit-risk relationship of exposure to fluorides for that age group. Community water fluoridation continues to be the most effective and socially equitable measure for caries prevention among all ages by achieving community-wide exposure to the caries preventive effects of fluoride.

AIM: To test whether residents of Queensland differ from residents elsewhere in Australia with respect to support for water fluoridation. METHODS: Questionnaire data were obtained from an Australia-wide sample of 517 adults. The study occurred in 2008, shortly after the state government mandated fluoridation across Queensland. RESULTS: There were no significant differences in fluoridation support or in beliefs regarding the benefits and harms of fluoridation between Queensland and non-Queensland residents. However, respondents from Queensland were more resistant to changing their minds regarding their fluoridation stance, more distrusting of public health officials, and more supportive of decisions to introduce fluoridation being made by the people via a referendum. After controlling for potentially confounding variables, Queenslanders demonstrated significantly more support for water fluoridation than non-Queenslanders. CONCLUSIONS: Perceived Queensland characteristics, which political scientists have used to explain aberrant political behavior or public policy, were not relevant to the longstanding pre-2009 disparity in water fluoridation coverage between Queensland and the rest of Australia. The findings of this investigation do not support the assumption that Queenslanders are more opposed to fluoridation than residents elsewhere in Australia.; Harry F. Akers & Jason M. Armfield

Objective: To estimate the level of support for water fluoridation across Australia and examine the association between water fluoridation stance and demographic and socioeconomic characteristics, commitment to the stance, and opinions, beliefs and knowledge regarding water fluoridation. Methods: Cross-sectional questionnaire data were obtained from 510 Australian adults (response rate = 34%) in 2008. Data were weighted by age, gender and state and territory estimated resident population. Main outcome measures: Participants were asked to rate the strength of their support for or opposition to water fluoridation on a 7-point scale. Results: Approximately 70% of survey respondents supported water fluoridation, 15.4% were opposed, and 14.5% were neutral. Those strongly opposed were most resistant to altering their opinion on the basis of new information or research. However, approximately 90% of people who were neutral, slightly supportive or moderately supportive would "maybe" or "definitely" change their stance. Fluoridation opposition was associated with lower income and educational attainment, more self-rated knowledge, and with beliefs about reduced benefits and greater harms. Opinions about who should be responsible for the introduction of water fluoridation and sources of information on fluoridation varied significantly by water fluoridation opinion. Conclusions: While this survey lends further weight to the evidence confirming extensive support for water fluoridation in Australia...

OBJECTIVES To review the effectiveness of adjusted fluoridation of public water supplies in the prevention of dental caries, with emphasis on results of studies published worldwide since 1990 and to discuss aspects of the design and reporting of these studies compared with those published before 1990. METHOD Studies published worldwide, in any language, reporting the effect of water fluoridation in terms of the dmf/DMF caries index between 1990 and 2010 were examined. The literature search was by professional Internet search, back-tracking from references given in publications, hand-searching all issues of four journals and by contacting colleagues in relevant countries. For the dmf index, age 5 year was preferred, and for the DMF index, age 12 year or older was preferred. The results were compared with results obtained from worldwide literature search prior to 1990 by the same author. RESULTS Fifty-nine studies of adjusted water fluoridation were identified, yielding 83 evaluations (30 recording dmft/s and 53 recording DMFT/S) from 10 countries. These numbers are lower than pre-1990 results of 113 studies (66 for primary and 86 for permanent teeth) from 23 countries. For the USA, for example, four studies were indentified since 1990 compared with 61 studies before 1990. The most number of recent reports came from Brazil and Australia. There were fewer reports of per cent caries reductions (% CR) above 50% in the recent studies. 86% of the post-1990 investigations were concurrent control cross-sectional studies and...

Objective: To investigate opinions and concerns of Gold Coast residents regarding fluoridation of community water supplies. Material and methods: Anonymous data were collected in four major shopping centers from approximately 500 Gold Coast residents. Results: Eighty-one percent of participants were aware of the addition of fluoride to the water supply. More than half obtained information on water fluoridation through the print and electronic media. Sixty percent of respondents supported water fluoridation. The majority preferred the public and/or health professionals to have made the decision on water fluoridation rather than the government. The percentage of residents supporting water fluoridation was lower than that found in other Queensland, Australian, and worldwide surveys. In this study, only age and the highest level of education attained were factors significantly related to levels of support for water fluoridation. Conclusion: The Queensland Government’s decision to implement water fluoridation without a referendum caused disquiet amongst some Gold Coast residents. Future public health initiatives therefore may be assisted by more consultation with, and involvement from, health professionals in the relevant fields. Public health campaigns may benefit more from interaction with the community in order to address their specific concerns.; Jeroen Kroon...

OBJECTIVES: Water fluoridation is one of the most effective public health programs of the past century. However, efforts to extend water fluoridation into currently non-fluoridated areas are often thwarted. Despite considerable evidence regarding the effectiveness of water fluoridation at an individual level, published national community-based studies are rare. This study compared children's decay experience and prevalence between areas with and without water fluoridation in Australia. METHODS: Oral health data were obtained from clinical examinations of 128, 990 5- to 15-year-old children attending for a regular visit with their respective Australian state or territory School Dental Service in 2002. Water fluoridation status, residence remoteness, and socioeconomic status (SES) were obtained for each child's recorded residential postcode area. RESULTS: Children from every age group had greater caries prevalence and more caries experience in areas with negligible fluoride concentrations in the water (<0.3 parts per million [ppm]) than in optimally fluoridated areas (> or = 0.7 ppm). Controlling for child age, residential location, and SES, deciduous and permanent caries experience was 28.7% and 31.6% higher, respectively, in low-fluoride areas compared with optimally fluoridated areas. The odds ratios for higher caries prevalence in areas with negligible fluoride compared with optimal fluoride were 1.34 (95% confidence interval [CI] 1.29...

BACKGROUND AND OVERVIEW Community water fluoridation is an important public health intervention that reduces oral health disparities and increases the health of the population. Promotion of its safety and effectiveness is critical to maintaining its widespread acceptance and ensuring its continued use. Dentists are a potentially important source of knowledge regarding the oral health benefits and safety of water fluoridation. However, few dentists regularly discuss fluorides, and water fluoridation in particular, with patients. The authors aim to describe and discuss the role and importance of dentists’ promotion of public water fluoridation, barriers to dentists’ involvement and some approaches that might influence dentists to promote water fluoridation more actively. CONCLUSIONS AND PRACTICE IMPLICATIONS Ongoing promotion of fluoridation by dentists is a key factor in ensuring sustained municipal water fluoridation. However, current undergraduate dental curricula do not adequately prepare dentists for this role, and continuing dental education may be insufficient to change clinical practice. Although smoking-cessation literature can shed some light on how to proceed, changing dentists’ practice behavior remains a largely unstudied topic. Dental associations are a key resource for dentists...

OBJECTIVES: A considerable body of evidence confirms that water fluoridation effectively reduces the community incidence of dental caries with minimal side effects. However, proposals to introduce this widely endorsed public-health measure are often perceived as controversial, and public opinion frequently plays a role in the outcome. Despite this, the public's perception of risk associated with water fluoridation has not been well researched and remains poorly understood. Our objectives were to determine whether risk perceptions reflecting various "outrage" factors are associated with water fluoridation support and opposition. METHODS: We conducted a cross-sectional questionnaire survey of a national sample of 517 Australian adults (response rate = 34.7 percent) aged 18-92 years. RESULTS: Approximately 70.5 percent of respondents supported water fluoridation, with 15.1 percent opposed and 14.3 percent neutral. Sixteen of the 20 assessed outrage factors were significantly associated with water fluoridation stance in the predicted direction, with greater outrage being related to increased water fluoridation opposition. An overall outrage index computed from the 16 significant outrage factors accounted for a statistically significant 58 percent of the variance in water fluoridation stance beyond the effects of age...

AIMS: Water fluoridation was extended in Queensland, Australia, across 2009-2011. A research program was commenced to inform the rationale for and the outcome of this program, to estimate the effectiveness of water fluoridation in preventing caries and to predict changes in caries experience as a result of the extension of fluoridation. METHODS: Queensland children were selected through a stratified random sample selection in 2010-2012. Oral epidemiological examinations provided individual-level outcomes for decayed, missing or filled primary or permanent tooth surfaces: dmfs (among 5-8-year-olds) and DMFS (9-14-year-olds). Explanatory factors at the individual-level, school-level and area-level fluoridation status were derived. Data were weighted to represent the population. Three-level multilevel multivariable models were sequentially specified for negative binomial distribution of dmfs/DMFS to estimate rate ratios (RR). The effectiveness of area-level water fluoridation was evaluated in the full models controlling for other factors. RESULTS: Data from 2,214 5-8 year-olds and 3,186 9-14 year-olds from 207 schools in 16 areas were analysed. Queensland's average dmfs was 4.23 and DMFS 1.47. The lowest levels of dental caries were observed in long-term fluoridated Townsville. In the full models...

PURPOSE: This population-based, cross-sectional study aimed to record the DMFT index for 12 year-old children with dental caries and fluorosis levels in cities with and without public water supply fluoridation. METHODS: From the 101 municipalities belonging to the Health Regional Department XV (DRS-XV-SJRP) of the São Paulo state in the Southeast region of Brazil, 85 cities were selected after exclusion of those with incomplete data and less than ten years of fluoridation treatment in 2004. The criteria adopted for the assessment of dental caries and fluorosis levels were based on the guidelines published in the WHO Manual 4th edition. The data were analyzed using Fisher's exact tests at a significance level of 5%. RESULTS: The prevalence of caries in 12 year-old children had no significant association with fluoridated water, and was considered "moderate" and "high" in cities without fluoridation and "low" and "moderate" in cities with fluoridation. A significant association was found between water fluoridation and fluorosis (P=0.001), but not between water fluoridation and the DMFT index (P=0.119). CONCLUSION: The prevalence of fluorosis was related to water fluoridation in this study. However, fluorosis was also observed in non-fluoridated cities...

; The aim of this study was to compare the dental caries prevalence, in the year 1998, in two cities of big population, one of them fluoridated, since 1975, the city of Bauru, and other, named Jaú, where the fluoridation was interrupted (1992). The two cities are located in the State of São Paulo, Brazil. The sample was composed by 189 children of 5 years old and 163 of 12 years old, both gender, distributed between Bauru and Jaú. The statistical analysis was made with use of the Student’s “t” test. The dental caries was registered with the use of the DMFT index and observed the percentage of children caries-free. No statistical differences were observed, considering the age and the cities. The outcomes showed that dmft of the 5 years old children in Bauru and Jaú were 1.06 1.32, respectively; and the DMFT of the 12 years old children were 2.92 and 3.45 respectively. The percentages of 5 years old caries free children in Bauru and Jaú were 54.84% and 55.21%, respectively. Considering the age of 12, the caries-free children were 21.34% in Bauru and 22.73% in Jaú. In the parameter evaluated the children living in Bauru, which has fluoridated water for more than 20 years, did not differ from the children from Jaú, which suffered interruption in the water fluoridation supply. Our results are differ from analysis performed during the decades of 70 and 80...
