The aim of this research was to determine the correlation between dental caries and socioeconomic conditions in the State of Paraná, Brazil. Caries prevalence was estimated for each city in the State by gathering data on the DMFT index (in 12-year-old schoolchildren) supplied by the State Health Department. Official socioeconomic data for the municipalities were also presented. Ordinary least squares regression analysis was performed, and significant correlation coefficients were observed between the dental caries index and various social development indicators. Maps highlighting the overlapping areas with poor outcomes for most of these variables were presented. The results showed a significantly lower DMFT index in cities with fluoridated water supply and a negative correlation between the caries index and the proportion of households with running water in cities with fluoridated water supply. This observation highlights the importance of fluoridated drinking water for the prevention of dental caries and as a measure to reduce the impact of socioeconomic inequalities on the prevalence of tooth decay.
本研究的目的是确定巴西巴拉那州龋齿与社会经济状况之间的相关性。通过收集该州卫生部提供的（12岁学童的）DMFT指数数据，估算该州每个城市的龋齿患病率。还展示了各市镇的官方社会经济数据。进行了普通最小二乘法回归分析，观察到龋齿指数与各种社会发展指标之间存在显著的相关系数。展示了突出这些变量中大多数结果不佳的重叠区域的地图。结果显示，在有氟化供水的城市中，DMFT指数显著较低，且在有氟化供水的城市中，龋齿指数与有自来水家庭的比例呈负相关。这一观察结果凸显了氟化饮用水对预防龋齿的重要性，以及作为减少社会经济不平等对龋齿患病率影响的一项措施的重要性。
