Objective: to analyze the oral health conditions of preschool children in Foz do Iguaçu, Paraná, Brazil, and their association with socioeconomic factors. Methods: a cross-sectional, descriptive study with a quantitative approach was conducted in September and October 2025. Eligible five-year-old children were examined by a dentist using the dmft index (decayed, missing due to extraction, and filled primary teeth). Sociodemographic variables were obtained through a structured digital questionnaire made available to parents via Google Forms. Results: overall, 59.7% of the children had a dmft score of zero, exceeding the historical WHO target of 50% of five-year-old children being caries-free. However, 32.5% had active caries experience, with a mean dmft of 1.75. Inferential analysis revealed a statistically significant association between dmft and participation in the Bolsa Família Program, as well as household income instability. Conclusion: the oral health status of the preschool children assessed reflects both progress toward the historical WHO target and the persistence of socioeconomic inequalities associated with caries experience, particularly those related to income instability.
