The scope of this study was to determine the prevalence of trauma in the permanent dentition of 12-year-old schoolchildren and assess associations with demographic factors such as gender and socioeconomic status and overjet and lip coverage clinical factors. A cross-sectional analysis was conducted using a representative sample of 638 students. Data were gathered by means of clinical examinations and self-administered questionnaires. Descriptive analysis was performed, followed by the use of the chi-square test and Poisson logistic regression model for the determination of significant associations. The prevalence of traumatic dental injury was 34.9%. Falls constituted the main etiological factor (49.7%), and occurred in the home (48.2%). The results of the Poisson regression analysis revealed that accentuated overjet (> 5 mm) remained associated with traumatic dental injury irrespective of the other variables [PR = 1.50 (95% CI: 1.41 to 1.61); p = 0.003]. Moreover, a statistically significant association was found between accentuated overjet and dental trauma. No significant associations were found between TDI and socioeconomic status. These findings highlight the need for prevention strategies and orthodontic correction at the onset of the permanent dentition.
本研究的范围是确定12岁学童恒牙列中创伤的患病率，并评估与性别和社会经济地位等人口统计学因素以及覆盖超突和唇覆盖等临床因素之间的关联。使用638名学生的代表性样本进行横断面分析。通过临床检查和自我管理问卷收集数据。进行描述性分析，然后使用卡方检验和泊松逻辑回归模型来确定显著关联。牙外伤的患病率为34.9%。跌倒构成主要病因（49.7%），且发生在家中（48.2%）。泊松回归分析结果显示，无论其他变量如何，严重覆盖超突（>5mm）仍与牙外伤相关[PR = 1.50（95%CI：1.41至1.61）；p = 0.003]。此外，在严重覆盖超突与牙外伤之间发现了具有统计学意义的关联。在牙外伤与社会经济地位之间未发现显著关联。这些发现凸显了在恒牙列开始时采取预防策略和正畸矫正的必要性。
