The aim of this study was to assess the prevalence and discriminate the associated factors between enamel fractures and other trauma/trauma sequelae in 8 to 10-year-old Brazilian schoolchildren. A representative sample of 1,201 children from public and private schools were enrolled in this cross-sectional study. Questionnaires about sociodemographic characteristics were answered by parents. The outcome variable (traumatic dental injury, TDI) was multi-categorized. Independent individual variables were sex, age, number of residents in household, parents/caregivers' level of education, family income, dental caries, and overjet. Type of school was considered an independent contextual variable. Multilevel analysis, bivariate, and multivariate multinomial logistic regression models were performed. The prevalence of TDI was 14.0% (2.8% with other trauma/trauma sequelae). The multilevel analysis revealed no significant difference between the type of school and TDI. The multinomial logistic regression showed that boys (OR = 2.3; 95%CI: 1.1-4.8), older children (OR = 1.8; 95%CI: 1.1-3.0) and individuals with an overjet > 3 mm (OR = 2.5; 95%CI: 1.0-6.2) were more likely to present other trauma/trauma sequelae. Enamel fracture was not significantly associated with any variables. The prevalence of TDI in 8 to 10-year-old schoolchildren was 14% but only 2.8% of other trauma/trauma sequelae. Differences regarding the associated factors of TDI involving enamel fracture or other trauma/trauma sequelae were detected, suggesting that the different TDI classification cannot be evaluated as a single category.
本研究旨在评估巴西8至10岁学童牙釉质骨折与其他创伤/创伤后遗症之间的患病率，并区分相关因素。本横断面研究纳入了来自公立和私立学校的1201名儿童的代表性样本。家长回答了关于社会人口学特征的问卷。结果变量（创伤性牙损伤，TDI）进行了多分类。独立的个体变量包括性别、年龄、家庭居住人数、父母/照顾者的教育水平、家庭收入、龋齿和覆盖度。学校类型被视为一个独立的背景变量。进行了多水平分析、双变量和多变量多项逻辑回归模型分析。TDI的患病率为14.0%（2.8%伴有其他创伤/创伤后遗症）。多水平分析显示学校类型与TDI之间无显著差异。多项逻辑回归显示，男孩（OR = 2.3；95%CI：1.1 - 4.8）、年龄较大的儿童（OR = 1.8；95%CI：1.1 - 3.0）和覆盖度> 3 mm的个体（OR = 2.5；95%CI：1.0 - 6.2）更有可能出现其他创伤/创伤后遗症。牙釉质骨折与任何变量均无显著关联。8至10岁学童中TDI的患病率为14%，但只有2.8%伴有其他创伤/创伤后遗症。检测到涉及牙釉质骨折或其他创伤/创伤后遗症的TDI相关因素存在差异，这表明不同的TDI分类不能作为一个单一类别进行评估。
