Impact of traumatic dental injuries and malocclusions on quality of life of preschool children: a population-based study.

???displayArticle.abstract???
BACKGROUND: Few studies assessed the impact of traumatic dental injuries (TDI) and malocclusions on the oral health-related quality of life (OHRQoL) in preschool children. AIM: To assess the impact of the presence of TDI and malocclusions, as well as its severity and types, respectively, on the OHRQoL of preschool children. DESIGN: The study was conducted in 1215 children aged 1-4 years old who attended the National Day of Children Vaccination in Diadema, Brazil. Parents answered the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS) and socio-demographic conditions. Calibrated dental examiners performed the oral examinations for TDI and malocclusions. Poisson regression models adjusted by dental caries associated the clinical and socio-demographic conditions with the outcome. RESULTS: The multivariate adjusted models showed associations between some individual domains of the B-ECOHIS and clinical and socio-demographic conditions (P < 0.05). The severity of TDI showed a negative impact on the symptoms domain and self-image/social interaction domain (P < 0.05). Children with complicated TDI were more likely to experience a negative impact on total B-ECOHIS scores (PR = 2.10; P = 0.048). CONCLUSIONS: The presence of complicated TDI and dental caries were associated with worse OHRQoL of Brazilian preschool children, whereas malocclusions do not.
