Este estudo teve como objetivo relatar a perda dentária em uma população rural, avaliando a contribuição de variáveis socioeconômicas e comportamentais e comparando os resultados com as metas da Organização Mundial da Saúde (OMS) para 2000 e 2010. Foram examinados 473 moradores, utilizando a metodologia, códigos e critérios propostos pela OMS. Os resultados foram processados no programa Epibuco e o teste qui-quadrado (p<0.05) foi utilizado para comparar o número de dentes perdidos com as variáveis estudadas. Do total de examinados, 17,8% são edêntulos totais, assim como 8% e 50,9% dos examinados pertencentes aos grupos etários de 35 a 44 e 65 a 74 anos, respectivamente. Iniciando precocemente nesta população, a perda dentária avançou consideravelmente com a idade, estando a situação muito aquém das metas estabelecidas pela OMS para 2010. O teste qui-quadrado revelou diferenças estatisticamente significantes quanto ao número de dentes perdidos pelos entrevistados com 35 anos de idade ou mais em relação à escolaridade, tipo de moradia e autopercepção da qualidade da fala. Torna-se necessário o desenvolvimento de programas de atenção à saúde bucal, a fim de diminuir os danos causados e prevenir a continuidade da tendência à mutilação.

This study aimed to report the dental loss in a rural population, evaluating the contribution of socioeconomic and behavioral variables and comparing the results with the goals of the World Health Organization (WHO) for 2000 and 2010. A total of 473 residents had been examined using the methodology, codes and criteria according to WHO guidelines. The results were processed using the Epibuco program and the chi-square test (p<0.05) were used to compare the number of teeth lost with the variables studied. From the total of people examined, 17.8% were total edentulous as well as 8% and 50.9% of the examined of the age groups of 35 to 44 and 65 to 74 years-old, respectively. Initiating precociously in his population, the dental loss advanced considerably with the age, being the situation much distant of the goals established by WHO for 2010. Chi-square test revealed statistically significant differences among the number of teeth lost by the interviewed with 35 years-old or more in relation to education level, housing and self-perception of the speak quality. The development of oral health attention programs becomes necessary, in order to reduce the actual damages and to prevent the continuity of this trend of mutilation.

The aim of this study was to determine the prevalence of enamel white spots and the quality of oral hygiene in children up to 36 months old, in municipalities with different fluoride levels in the water supply, analyzing the contribution of several variables. After approval of the Ethics Committee, the parents signed an informed consent form and were interviewed about their educational level, economic classification of the family, nursing habits, use of toothpaste, access to dental service and other information. The children were clinically examined using the same codes and criteria established by the WHO (World Health Organization) and ADA (American Dental Association). The data were processed and analyzed with the Epi-info software program, version 3.2, and Microsoft Excel. Fisher's exact test (p<0.05) was applied to assess the association among the variables. The enamel white spot prevalence was 30.8% and the age group, duration of the bedtime milk feeding habit, age of initial practice of oral hygiene and presence of caries lesions with cavitation were considered statistically significant with regard to enamel white spot prevalence (p < 0.05). No association was found between oral hygiene quality and the study variables.

This study determined the prevalence of cavitated caries lesions (CCL) and early childhood caries (ECC), and the contribution of some variables in children up to 36 months of age attending daycare centers in municipalities with different fluoride levels in the water supply: AFC (adequate fluoride content) and LFC (low fluoride content). After approval of the Ethics Committee, the parents were interviewed. The children were clinically examined using the same codes and criteria established by the WHO (World Health Organization) and the ADA (American Dental Association). Fisher's exact test (p<0.05) was applied for statistical analysis of data. The dmft indices calculated in the LFC and AFC municipalities were 0.57 and 0.68, respectively. Considering all children examined, 17.6% presented CCL and 33.8% ECC. The economic classification, mother's education level and duration of breastfeeding were considered statistically significant with regards to CCL prevalence. The age group, duration of the habit of drinking milk before bedtime and age at which oral hygiene started were considered statistically significant with regards to ECC prevalence.

Municípios de pequeno e médio porte podem ter dificuldades em realizar o controle da adição de flúor nas águas de abastecimento público em função da falta de infra-estrutura laboratorial e técnica. Este estudo realizou análises do teor de flúor das águas de abastecimento de 40 municípios situados na região noroeste do estado de São Paulo, durante 6 meses, para verificar se a adição ocorre de forma contínua e se os teores adicionados encontram-se dentro dos parâmetros recomendados. Mapas com a rede de distribuição de água dos municípios foram solicitados e utilizados para definir as regiões de coleta e sortear os endereços dos pontos, de forma que abrangessem todas as fontes de água tratada. Uma amostra de água de cada ponto foi coletada por mês e analisada em duplicata pelo método íon-eletrodo específico. Amostras com 0,6 a 0,8 mg F/L foram consideradas aceitáveis. Nos 38 municípios que enviaram as amostras regularmente nos 6 meses de estudo, a água de 144 pontos foi coletada, perfazendo um total de 864 amostras analisadas, das quais 61,81% foram classificadas como inaceitáveis. Constatou-se que 33 destes municípios realizavam a fluoretação, sendo que em 78,79% deles as concentrações de flúor variavam entre os pontos e no mesmo ponto ao longo do período. Pode-se concluir que a maioria destes municípios não mantém controle adequado sobre os níveis de flúor em sua água, pois a adição de flúor ocorre de forma descontínua e na maioria das vezes em teores fora dos parâmetros recomendados.

It may be difficult for small and medium cities to obtain information about the fluoride content of public water, because of the lack of equipments and technicians. This study aimed to analyze the fluoride levels of the water supplied by the public treatment stations of 40 cities situated in the northwest region of São Paulo State, during a period of 6 months, to verify if fluoridation occurs in a continuous manner and if the fluoride levels are within the recommended. Maps of the water distribution system were obtained from the water treatment companies and utilized to randomize the addresses of the collection sites, so that they included all regions with treated water sources. One water sample by month was collected and analyzed in duplicate using an ion-specific-electrode. Samples with 0.6 to 0.8 mgF/L were considered acceptable. In the 38 cities that regularly provided the samples in the 6 months of the study, water from 144 collection sites was collected and a total of 864 samples were analyzed, of which 61.81 percent were classified as unacceptable. It was observed that 33 cities performed fluoridation but in 78.79 percent of these cities there were variations in the fluoride level among the sites and in the same site during the period of study. One can conclude that most of these cities do not control the fluoride levels in the public water, since fluoridation occurs in a discontinuous manner and in most of the situations not within the recommended concentrations.
