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.
这是一项观察性、分析性和横断面研究，旨在评估巴西米纳斯吉拉斯州北部地方性氟牙症农村社区中氟牙症严重程度与患病率以及龋齿之间的关联，这些社区水氟浓度高达4.8毫克/升。由一名检查者在刷牙后收集数据（检查者内龋齿和氟牙症的kappa值为0.96至0.95）。该研究纳入了511名7至22岁的个体，按年龄分类：7至9岁（n = 227），10至12岁（n = 153），13至15岁（n = 92），16至22岁（n = 39）。对于龋齿的诊断，使用世界卫生组织的标准来测量DMFT指数。对于氟牙症，使用Thylstrup和Fejerskov指数（TF），根据患病率（TF = 0和TF> 0）和严重程度（TF <4和TF> 5）进行二分法分类。在两个较年轻的组中，氟牙症更严重的组中DMFT及其龋坏成分更高（p <0.001）。在青少年和成年人中未发现这种关联（p> 0.05）。在12岁以下个体中，发现更严重的氟牙症与龋齿之间存在关联。
