However, it is not known whether the dental injury is associated with alcohol consumption.Methods In 2009–2010 we carried out a cross-sectional study among a random sample of 687 adolescents (aged 14–19 years) from public and private schools in Diamantina, Minas Gerais, Brazil. Information on dental injuries and alcohol consumption were collected via a clinical examination by one researcher (intra-examiner κ=0.93) and a self-administered questionnaire: Alcohol Use Disorders Identification Test (AUDIT), validated in Brazil. Study in public or private school was used for socioeconomic indicator.Results The prevalence of dental injuries was 26.6% and the prevalence of risk from hazardous levels of alcohol consumption was 44%. The traumatic dental injuries were significantly associated with the high risk of alcohol consumption (p=0.031), hazardous use (p=0.009) and binge drinking (p=0.036). The Results of the logistic regression revealed that hazardous use (OR −1.4 CI 1.007 to 2.061), remained associated with traumatic dental injury independent of other variables as age, gender, overjet and type of school.Conclusions There is a high prevalence of traumatic dental injuries and hazardous alcohol use among adolescents, and alcohol consumption was associated with the prevalence of dental injuries.
