我们对有和没有牙齿外伤的青少年进行了为期2年的随访，估计了创伤性牙损伤（TDI）的发生率，并验证了有外伤的个体更容易发生复发性TDI事件的假设。本研究分三个阶段进行。首先，对巴西南部比瓜帕拉苏11-13岁的2260名学童进行了牙外伤横断面研究。在第二阶段，开展了一项病例对照研究，以确定与牙齿创伤相关的危险因素。第三步是一项为期2年的纵向观察研究，参与者参加了第二阶段的研究。有牙齿外伤的暴露组（208人）和没有牙齿外伤迹象的未暴露组（208人）随访2年。进行描述性、单变量、简单和条件多元逻辑回归分析。有牙外伤青少年的牙外伤发生率（11.9% ~ 11.44/1000）高于无牙外伤青少年（2.7% ~ 2.45/1000）（P < 0.001）。在研究期间，与没有牙外伤的青少年相比，有牙外伤史的青少年出现进一步牙外伤的优势比为4.85倍（P = 0.005），调整了切牙覆盖、唇部覆盖和母亲受教育程度。在病例组和对照组之间观察到TDI发生率的显著差异。在2年的随访中，先前有牙外伤的个体有更大的机会发展成进一步的牙外伤。
We estimated the incidence of traumatic dental injuries (TDI) in a 2-year follow-up of adolescents with and without previous dental trauma and verified the hypothesis that individuals with previous trauma are more prone to recurrent TDI events. The present study was developed in three phases. First, a dental trauma cross-sectional study was carried out with 2260 schoolchildren aged 11-13 years in Biguaçu, southern Brazil. In the second phase, a case-control study was developed to identify risk factors associated with dental trauma. The third step was a 2-year longitudinal observational study with the participants of the second phase of the study. The exposed group of individuals with previous dental traumatism (208) and a non-exposed group (208) of participants who had no previous signs of dental trauma were followed up for 2 years. Descriptive, univariate, simple and conditional multiple logistic regression analyses were performed. The greatest incidence of dental trauma was identified among adolescents with previous dental trauma (11.9%-11.44/1000 incisors) when compared with those without previous dental trauma (2.7%-2.45/1000 incisors) (P < 0.001). In the study period, adolescents with previous dental trauma showed a 4.85 times greater odds ratio for presenting further dental trauma when compared with adolescents without previous dental trauma (P = 0,005) after adjusting for incisal overjet, lip coverage and mother's schooling. A notable difference was observed regarding the incidence of TDI between the case and control groups. Individuals with previous dental trauma had greater chances of developing develop further dental trauma in a 2-year follow-up.
