BACKGROUND: Few studies have evaluated the oral health status of children with a history of maltreatment. AIM: This case-control study evaluated oral health in children who were victims of abuse and in child protective services in Curitiba, Brazil. DESIGN: One hundred twenty-two children who were victims of abuse and 240 children with no history of abuse (mean ages, 8.56 and 8.24 years, respectively) were included in the study. Dental caries were assessed according to the Decayed, Missing, or Filled Teeth index (dmft index and DMFT index) by two calibrated examiners. The presence of anterior open bite and posterior crossbite was recorded. Data were analyzed using bivariate and adjusted odds ratios using a multivariate logistic regression model analyses. RESULTS: In the case group, we found a higher DMFT index (P < 0.001) and a significantly higher prevalence of missing primary teeth (P = 0.04), untreated decayed permanent teeth (P < 0.001), filled permanent teeth (P < 0.001), and anterior open bite (P = 0.04). Children who were victims of abuse presented an odds ratio of 6.48 (95% CI: 3.52-11.95) for caries in permanent teeth and an odds ratio of 2.28 (95% CI: 1.04-4.99) for open bite. CONCLUSION: Victims of child abuse had a worse oral health status, demonstrating the need to establish special policies for oral healthcare for this population.
