Background: Traumatic dental injury (TDI) has been considered a significant problem in youth, not only because of its consequences to the craniofacial structures but also for its potential impact on the quality of life of affected individuals. Aim: The aim of this study was to investigate the impact of TDI with treatment needs on the oral health-related quality of life (OHRQoL) of South Brazilian schoolchildren. Design: A cross-sectional study was performed in Porto Alegre, Brazil, using a multistage probability sampling strategy. Of 1837 eligible 12-year-old schoolchildren attending public and private schools, 1528 were examined. OHRQoL was assessed by the Brazilian version of the Child Perceptions Questionnaire for 11-to 14-year-old children (CPQ11-14) - 16-item short form. Clinical examination was conducted to assess the presence of TDI in permanent incisors (Children's Dental Health Survey criteria), malocclusion, and dental caries. Parents/legal guardians answered questions on socioeconomic status. Statistical analyses were performed using Poisson regression models. Results: The overall CPQ11-14 score was not associated with TDI. In the functional limitations domain, individuals presenting TDIs with treatment needs experienced significantly higher mean CPQ11-14 than individuals with no TDI or without treatment needs (RR = 1.21; 95% CI = 1.05-1.39), after adjusting for malocclusion, dental caries, gender, and socioeconomic status. No other domains were associated with TDI. Conclusions: This study revealed that TDI with treatment needs negatively affects the OHRQoL in this population of 12-year-old schoolchildren and that this impact is related to oral functions.
