Resumo: Purpose: The objective of this study was to map out the residual levels of fluoride in isolated wells belonging to the municipality of São Luis, Maranhão, Brazil, during the period of August of 2009. Methods: The wells were determined according to sectors of the company responsible for the public water supply. Collection points were near these wells. The analysis of fluoride concentration was carried out in triplicate, using an ion-specific electrode for fluoride connected to a previously calibrated temperature meter. After analysis, samples were considered adequate when the fluoride concentration was within the recommended limits from 0.60 to 0.80 ppm F (criteria I) or within the stipulated range from 0.55 ppm F to 0.84 ppm F (criteria II). Results: The results show levels of residual fluoride less than 0.11 ppm in the water of isolated wells. Conclusion: It may be concluded that the population of São Luis, supplied with water from its wells, does not benefit from the method of fluoridation. The levels of residual fluoride found cannot cause dental fluorosis in its most severe forms, nor even prevent dental caries.

Métodos: Os poços foram estabelecidos a partir das áreas de atuação da Companhia responsável pelo abastecimento público de água, sendo os pontos de coleta próximos a cada um desses poços. A análise da concentração de flúor foi realizada em triplicata, utilizando-se um eletrodo íon-específico para flúor conectado a um potenciômetro previamente calibrado. Após analisadas, as amostras foram consideradas adequadas quando a concentração de flúor estava dentro dos limites recomendados de 0,60 a 0,80 ppm F (critério I) ou dentro do intervalo estipulado de 0,55 ppm F a 0,84 ppm F (critério II). Resultados: Os resultados demonstraram teores de flúor residual inferiores a 0,11 ppm nas águas dos poços isolados. Conclusão: Conclui-se que a população ludovicense abastecida pelas águas desses poços não está sendo beneficiada pelo método da fluoretação. Os teores de flúor residual encontrados não são capazes de promover o desenvolvimento de fluorose dentária em suas formas mais severas, ou mesmo de proporcionar prevenção à cárie dentária.EDIPUCRS - Editora Universitária da PUCRS2012-12-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/11136Revista Odonto Ciência; Vol. 27 No. 4 (2012); 304-308Revista Odonto Ciência; v. 27 n. 4 (2012); 304-3081980-65230102-9460reponame:Revista odonto ciência (Online)instname:Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)instacron:PUC_RSenghttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/11136/10153Paredes, Suyene de OliveiraSampaio, Fábio CorreiaForte, Franklin Delano Soaresinfo:eu-repo/semantics/openAccess2013-10-26T01:39:16Zoai:ojs.revistaseletronicas.pucrs.br:article/11136Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2013-10-26T01:39:16Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false
