The aim of the present study was to assess the impact of traumatic dental injury (TDI) on oral health-related quality of life (OHRQoL) among preschool children in the city of Belo Horizonte, Brazil. A representative cross-sectional study and a population-based matched case-control study were carried out. The samples were composed of male and female preschool children aged 60 to 71 months. The sample in the cross-sectional study was composed of 1632 preschool children. The sample in the case-control study was composed of 58 children with an impact on OHRQoL in the case group and 232 children without impact in the control group. Pilot studies were conducted prior to the main studies to test the methodologies. Data on OHRQoL were collected using the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS), which was administered to parents/caregivers toobtain their perceptions regarding the oral health of their children. The BECOHIS and a form addressing demographic data and history of TDI were sent to the parents/caregivers. Socioeconomic status was determined based on the Social Vulnerability Index, family income, number of residents in the household and parents/caregivers schooling. Oral examinations were performed on the children by a single calibrated dentist using the classification proposed by Andreasen et al. (2007). Descriptive, bivariate and multiple Poisson regression analyses were carried out in the cross-sectional study. Descriptive statistics and conditional logistic regression analysis were employed in the case-control study. The level of significance was set at 5%. The prevalence of OHRQoL among the children and families was 36.8% and31.4%, respectively. In the cross-sectional study, no statistically significant associations were found between TDI and the OHRQoL of the children or families (p > 0.05). However, the presence of tooth avulsion remained in the final multiple models of OHRQoL of the children and families [PR=1.37, 95% CI=1.02-1.85; PR=1.55, 95% CI=1.12-2.14, respectively]. In the case-control study, the conditional logistic regression revealed no statistically significant difference in the prevalence of TDI between the cases and controls (p > 0.05). The presence of TDI had no impact on the OHRQoL of preschool children and their families in Belo Horizonte. However, the presence of dental avulsion was associated with a higher prevalence rate of negative impact on OHRQoL of both the children and families.
