title: Alcohol consumption at age 11-12 years and traumatic dental injuries at age 15-16 years in school children from East London.
abstract: OBJECTIVE
  To explore the association between alcohol consumption at age 11-12 years and traumatic dental injuries (TDI) at age 15-16 years.
  
  
  METHODS
  Data of 635 adolescents who participated in phases I and III of the Research with East London Adolescents Community Health Survey (RELACHS), a longitudinal school-based survey of a representative sample of adolescents from East London, were used for this study. Information on socio-demographic characteristics and alcohol consumption was obtained from questionnaires in phase I when adolescents were 11-12 years of age. Data on TDI and clinical characteristics (incisor overjet and lip coverage) were taken from clinical examination in phase III when adolescents were 15-16 years of age. The association between (lifetime and last month) alcohol consumption and TDI was assessed in crude and adjusted logistic regression models.
  
  
  RESULTS
  Overall, 14.5% of adolescents had ever consumed alcohol and 3.5% had consumed alcohol the month before the baseline survey, whereas 17% of adolescents had experienced TDI by age 15-16 years. No significant association of alcohol consumption with TDI was seen in these adolescents for either lifetime (adjusted odds ratio [OR]: 0.87; 95% confidence interval [CI]: 0.45-1.67) or last month consumption of alcohol (adjusted OR: 0.86; 95% CI: 0.28-2.69).
  
  
  CONCLUSIONS
  This study did not support the association between alcohol use and TDI in adolescents.
