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.
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).
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.
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.
本研究旨在调查巴西贝洛奥里藏特市青少年的牙齿外伤流行率、病因、易患因素以及与社会经济地位的关联，同时调查其与酒精和非法药物使用的相关性。
进行了一项横断面研究，包括临床检查和自我管理问卷调查。样本人群由来自公立和私立学校的 891 名青少年组成。采用社会脆弱性指数（SVI）对社会经济状况进行分类。使用两个问卷获得关于酒精和非法药物使用的信息：酒精使用障碍识别测试（AUDIT）和酒精、吸烟和物质使用参与筛查测试（ASSIST）。
牙齿外伤（TDI）的患病率为 24.7%。跌倒（17.7%）是导致牙齿受伤的最常见病因。在有 TDI 的参与者中，32.8%的人在私立学校系统就读（P=0.006）。有明显前牙深覆合的人中，有 32.8%的人患有某种类型的 TDI（P=0.000）。大量青少年有饮酒行为（50.3%）和使用非法物质（15.2%）。然而，这些变量与 TDI 的存在之间没有发现统计学上的显著关联。分析结果表明，私立学校系统的个体（优势比[PR]=1.11；95%置信区间[CI]：1.03-1.20）和有明显前牙深覆合（>3mm）的个体（PR=1.17；95%CI：1.10-1.25）属于 TDI 诊断类型的个体的几率分别增加了 1.11 倍和 1.17 倍。
研究人群中牙齿外伤的流行率较高。同样，在所检查的青少年中，酒精和非法药物的使用也很高，尽管这些变量与 TDI 病史之间没有发现统计学上的显著关联。私立学校系统和明显的前牙深覆合与牙齿外伤显著相关。
