Despite the improvement of the lives of Brazilians, still persists a panorama of iniquities in health in Brazil. This ecological study evaluated the relationship of socioeconomic conditions and public health policy with oral health conditions in Brazilian capitals. Factor analysis was performed with the socioeconomic indicators, revealing two common factors: economic deprivation and socio-sanitary condition. Then, was executed multiple linear regression analysis for the oral health indicators (average DMFT 12 years, mean missing teeth and rate of decay of free population) with two factors in common and fluoridation of water supply. Multiple linear regression analysis to the DMFT of the capitals was estimated by the socio-sanitary conditions and fluoridation, adjusted by economic deprivation; whereas the model for the average missing teeth was estimated only for flu-oridation and economic deprivation, and finally, the model for the rate of caries-free population in the Brazilian capitals was estimated by economic and sociosanitary condition set by fluoridated water supplies. Therefore, the results indicate the need for social actions that impact on people's living conditions to reduce tooth decay.
