title: Prevalence of traumatic dental injuries and its association with binge drinking among 12-year-olds: a population-based study.
abstract: OBJECTIVE
  To determine the prevalence of traumatic dental injuries and its association with binge drinking among 12-year-old schoolchildren.
  
  
  METHODS
  A cross-sectional study was carried out involving 588 students from a medium-sized city in Brazil. Data were collected through a clinical examination and self-administered questionnaires. Andreasen's classification was used for the determination of traumatic dental injuries. The consumption of alcoholic beverages and binge drinking were evaluated using the Alcohol Use Disorders Identification Test--Consumption. Socio-economic status, overjet, and inadequate lip seal were also analysed. Associations were tested using the multivariate logistic regression analysis.
  
  
  RESULTS
  The prevalence rates of traumatic dental injuries, alcohol consumption in one's lifetime, and binge drinking were 29.9%, 45.6%, and 23.1%, respectively. The prevalence of traumatic dental injuries was significantly higher among those who engaged in binge drinking (PR = 1.410; 95% CI: 1.133-1.754) and even higher among those with inadequate lip protection and accentuated overjet (PR = 3.288; 95% CI: 2.391-4.522 and PR = 1.838; 95% CI: 1.470-2.298, respectively).
  
  
  CONCLUSIONS
  A higher prevalence rate of traumatic dental injuries was found among 12-year-olds who engaged in binge drinking. The high rate of alcohol intake among adolescents is worrisome considering the vulnerability of this population due to the intense transformations that occur in the transition from childhood to adulthood.
