The aim of this study was to evaluate cases of dental trauma treated at the specialized center of Pontifical Catholic University of Paraná, Curitiba, Brazil, during a period of 2 years.
A total of 647 patients were evaluated and treated between 2003 and 2005. Data obtained from each patient were tabulated and analyzed as to gender, age, etiology, time elapsed after the injury, diagnosis (type of trauma), and affected teeth.
The results revealed that male individuals aged 7 to 13 years presented the highest prevalence of injury, and falling was the main causal factor. In most cases, the time elapsed between the accident and the first care ranged from 4 to 24 h. A total of 1,747 teeth were affected, with higher incidence of concussion/subluxation and coronal fracture, followed by lateral luxation and avulsion. The permanent maxillary central incisors were the most commonly affected teeth.
The frequency and causes of dentoalveolar trauma should be investigated for identification of risk groups, treatment demands and costs in order to allow for the establishment of effective preventive measures that can reduce the treatment duration and costs for both patients and oral health services.
本研究旨在评估巴西库里提巴市巴西天主教大学牙外伤专科中心在 2 年期间所治疗的牙外伤病例。
2003 年至 2005 年期间，共对 647 名患者进行了评估和治疗。对每位患者的数据进行列表并进行分析，分析内容包括性别、年龄、病因、受伤后时间、诊断（创伤类型）和受影响的牙齿。
结果显示，7 至 13 岁的男性个体受伤发生率最高，跌倒为主要致伤因素。在大多数情况下，事故发生与首次就诊之间的时间间隔为 4 至 24 小时。共有 1747 颗牙齿受到影响，其中震荡/半脱位和冠部骨折的发生率较高，其次是侧向脱位和牙脱位。上颌恒中切牙最常受影响。
应调查牙外伤的频率和原因，以确定风险群体、治疗需求和成本，以便制定有效的预防措施，减少患者和口腔卫生服务的治疗时间和成本。
