Abstract
It is observational, analytical and cross-sectional aimed to evaluate the association between severity and prevalence of fluorosis and dental caries in rural communities with endemic dental fluorosis in the north state of Minas Gerais, Brazil, with fluoride concentrations in water up to 4.8 mg/L. Data were collected by one examiner (intra-examiner kappa, 0.96 to 0,95 for caries and fluorosis) after toothbrushing. The study included 511 individuals aged 7 - 22 years, categorized according to age: 7 - 9 years (n = 227), 10 to 12 years (n = 153), 13 to 15 years (n = 92), 16 to 22 years (n = 39). For the diagnosis of dental caries used the criteria of the World Health Organization to measure indices DMFT. For fluorosis used the index Thylstrup and Fejerskov (TF), dichotomized according to prevalence (TF = 0 and TF > 0) and severity (TF < 4 and TF > 5). In the two younger groups, the DMFT and its decay component were higher in the group with more severe fluorosis (p < 0.001). This association was not found among adolescents and adults (p > 0.05). The association was found between the conditions more severe fluorosis and caries in individuals under 12 years.
Highlights
Trata-se de estudo transversal e analítico cujo objetivo foi avaliar a associação entre a prevalência e a gravidade da fluorose e da cárie dentária em municípios rurais com fluorose endêmica no norte do Estado de Minas Gerais, Brasil, com concentração de flúor nas águas de até 4,8 mg/L
Artesian wells were used as an alternative against droughts by communities living in this impoverished area, between 1978 and 1998, and as the only water supply resource, resulting in endemic fluorosis[8] caused by the presence of fluorite in the soil
The high temperatures in this area result in greater water consumption, which could have contributed to endemic fluorosis in the community
Summary
Trata-se de estudo transversal e analítico cujo objetivo foi avaliar a associação entre a prevalência e a gravidade da fluorose e da cárie dentária em municípios rurais com fluorose endêmica no norte do Estado de Minas Gerais, Brasil, com concentração de flúor nas águas de até 4,8 mg/L. Os dados foram coletados por um examinador (Kappa intra examinador, 0,96 para fluorose e 0,95 para cárie) após escovação dentária. Para a fluorose utilizou-se o índice de Thylstrup e Fejerskov (TF), dicotomizado segundo a prevalência (TF = 0 e TF > 0) e gravidade (TF ≤ 4 e TF ≥ 5).Nos dois grupos mais jovens, o CPO-D e seu componente cariado foram maiores no grupo com fluorose mais grave (p < 0,001). A associação mais grave entre as condições cárie e fluorose foi encontrada em indivíduos com até 12 anos
