Prevalence of traumatic dental injuries and its association with binge drinking among 12-year-olds: a population-based study.

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.

Association between dental trauma and alcohol use among adolescents.

AIM: To investigate the association between dental trauma and alcohol use among adolescents between 14 and 19 years of age. MATERIALS AND METHODS: A cross-sectional study was carried out involving a clinical exam performed by a calibrated researcher (intra-examiner Kappa = 0.93) and a self-administered questionnaire. The sample was representative of schoolchildren from the city of Diamantina (Brazil) and was made up of 738 adolescents. The type of school (public or private) was used as a socioeconomic indicator. Information on alcohol use (high risk and hazardous use) was acquired through the administration of the Alcohol Use Disorders Identification Test, which has been validated for use in Brazil. RESULTS: The prevalence of dental trauma was 26.6%, and the prevalence of dangerous alcohol use was 44.3%. Dental trauma was significantly associated with a high risk of problems related to alcohol intake (P = 0.031), hazardous alcohol use (P = 0.009) and binge drinking (P = 0.036). The results of the Poisson logistic regression revealed that hazardous alcohol use [PR = 1.30 (95% CI: 1.01-1.66) P = 0.042] remained associated with dental trauma independently from age, gender, overjet, and type of school. CONCLUSIONS: The high prevalence of dental trauma found among adolescents in the city of Diamantina (Brazil) was greater among those at high risk for problems related to alcohol intake and was significantly associated with hazardous alcohol use.

Prevalence and association of dental injuries with socioeconomic conditions and alcohol/drug use in adolescents between 15 and 19 years of age.

BACKGROUND: The aim of the present study was to investigate the prevalence of dental trauma, etiological factors, predisposing factors, and associations with socioeconomic status and the risk of alcohol and illicit drug use among adolescents in the city of Belo Horizonte, Brazil. METHODS: A cross-sectional study was carried out that included clinical examinations and self-administered questionnaires. The sample population was composed of 891 adolescents from public and private schools. The Social Vulnerability Index (SVI) was used for socioeconomic classification. Information on alcohol and illicit drug use was obtained using two questionnaires: the Alcohol Use Disorders Identification Test (AUDIT) and the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). RESULTS: The prevalence of traumatic dental injury (TDI) was 24.7%. Falls (17.7%) was the most frequently cited etiological factor in dental injury. Among the participants with TDI, 32.8% were students in the private school system (P = 0.006). A total of 56.8% of individuals with accentuated overjet had some type of TDI (P = 0.000). There was a high prevalence of adolescents who consumed alcoholic beverages (50.3%) and used illicit substances (15.2%). However, no statistically significant associations were found between these variables and the presence of TDI. The results of the analysis demonstrate that individuals in a private school system [prevalence ratio (PR) = 1.11; 95% confidence interval (CI): 1.03-1.20] and those with accentuated overjet (>3 mm) (PR = 1.17; 95% CI: 1.10-1.25) had a 1.11- and 1.17-fold greater chance of belonging to the group of individuals diagnosed with some type of TDI. CONCLUSIONS: The prevalence of dental trauma in the study population was high. The same was true regarding alcohol and illicit drug use among the adolescents examined, although no statistically significant associations were found between these variables and a history of TDI. Private school system and accentuated overjet were significantly associated with dental trauma.
