Impacto da Estratégia Saúde da Família sobre indicadores de saúde bucal: análise em municípios do Nordeste brasileiro com mais de 100 mil habitantes

this study aimed to analyze the impact of the family health strategy (fhs) on oral health in northeast brazil, in 12 municipalities with more than 100 thousand inhabitants. the reference was 20 census tracts, 10 of which in areas with oral health covered by the fhs for at least a year, matched with 10 census tracts without oral health coverage. the total sample included 59,221 individuals. three possible effects were considered: negative, positive, and absence of effect on the outcomes, based on the prevalence ratio adjusted by poisson regression. the outcomes "access to collective preventive measures" and "treatment of toothache" indicate a positive effect in the fhs oral health model. however, the outcomes "coverage of tooth extraction" and "restorative treatment" showed either a negative effect or no effect in the majority of the municipalities in the sample. evidence indicates that within the fhs, the results reflect the local organizational models for oral health care.
