Resumo: Objective: To determine the relationship between dental fluorosis (DF) severity and fluoride [F] concentration in tooth and water in DF endemic areas. Methods: Life-long residents from two DF endemic communities were studied. Forty-five extracted teeth were collected and analyzed for DF severity and tooth [F]. Thylstrup-Ferjeskov Index (TFI) was used to measure DF severity and instrumental neutron activation analysis (INAA) for tooth [F] concentration. Water from regional wells was also collected (n=9) and analyzed for F content using specific ion F electrode. Results: Water [F] varied between 0.2ppm and 4.7ppm. TFI scores ranged from 0 to 6; [F] from 120ppm to 2,140ppm in enamel and 304ppm to 4,800ppm in dentin. No correlation was found between DF severity and [F] in enamel (rs=0.22,p=0.15) and dentin (rs=-0.19,p=0.20), nor between water [F] and [F] in enamel (rs=-0.09,p=0.65) and dentin (rs=-0.11,p=0.56). Weak correlation between DF severity and water [F] (rs=0.38,p=0.04) was found. Linear regression analysis showed that TFI couldn’t be predicted from a linear combination of the independent variables (age, enamel and dentin [F]). When enamel, dentin and water [F] were used as independent variables in the linear regression (predict DF severity), only water [F] showed influence in DF severity (p=0.013;t=2.67). Conclusion: Even in areas of endemic DF, tooth [F] didn’t correlate with DF severity and the relationship between water [F] and DF severity was very weak. Therefore, tooth [F] may not be a good predictor/indicator of DF severity.

Métodos: Residentes de duas comunidades endêmicas de FD foram estudados. 45 dentes foram coletados e analisados para severidade de FD e concentração de flúor. O índice de Thylstrup-Ferjeskov (TFI) foi utilizado para medir a severidade de FD e análise por ativação com nêutrons (AAN) para concentração de [F] dental. Águas de poços da região foram coletadas (n=9) e analisadas para [F], utilizando eletrodo específico de flúor. Resultados: Concentração de [F] da água variou entre 0,2 e 4,7ppm. Os escores do TFI variaram entre 0 e 6; [F] no esmalte entre 120 e 2140ppm e na dentina entre 304 e 4800ppm. Não se observou correlação entre severidade de DF e [F] no esmalte (rs=0,22,p=0,15) e dentina (rs=-0,11,p=0,56). Encontrou-se correlação fraca entre FD e [F] na água (rs=0,38,p=0,04). Análise de regressão linear demonstrou que TFI não podia ser predito por uma combinação linear das variáveis (idade, e concentração de flúor no esmalte e dentina). Quando a concentração de flúor no esmalte, dentina e água foram analisadas de forma independente na regressão linear, apenas flúor na água demonstrou influência na severidade de FD (p=0,013;t=2,67). Conclusão: Mesmo em áreas endêmicas de FD, concentração de flúor dental não se correlaciona com severidade de FD, e a relação entre este e a concentração de flúor nas águas foi fraca. Assim, concentração de flúor dental pode não ser um bom preditor/indicador de severidade de FD.Universidade de Fortaleza2012-01-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion"Peer-reviewed Article""Avaliado pelos pares""Avaliado pelos pares"application/pdfhttps://ojs.unifor.br/RBPS/article/view/209310.5020/2093Brazilian Journal in Health Promotion; Vol. 24 No. 4 (2011); 355-360Revista Brasileña en Promoción de la Salud; Vol. 24 Núm. 4 (2011); 355-360Revista Brasileira em Promoção da Saúde; v. 24 n. 4 (2011); 355-3601806-1230reponame:Revista Brasileira em Promoção da Saúdeinstname:Universidade de Fortaleza (Unifor)instacron:UFORporhttps://ojs.unifor.br/RBPS/article/view/2093/2386Grynpas, Marc DanielHancock, RonSampaio, Fabio CorreiaLimeback, HardySaintrain, Maria VieiraVieira, Anya Pimentel Gomes Fernandesinfo:eu-repo/semantics/openAccess2012-01-23T16:35:18Zoai:ojs.ojs.unifor.br:article/2093Revistahttps://periodicos.unifor.br/RBPS/oai1806-12301806-1222opendoar:2012-01-23T16:35:18Revista Brasileira em Promoção da Saúde - Universidade de Fortaleza (Unifor)false
