Traumatic dental injury is one of the common injuries seen in the emergency department. To determine the distribution features of emergency traumatic dental injuries in Xi'an, China, data from the medical records of 623 patients (aged 6-78 years) were evaluated and analyzed according to age, gender, etiology, factors predisposing teeth to injury, and types of teeth traumatized. The patient records of 397 males (63.7%) and 226 females (36.3%), with a 1.8:1 male-to-female ratio, were included. The total number of traumatized teeth was 1475. The highest frequency of dental trauma was found in the 19- to 30-year age group (30.7%). The greatest frequency of dental trauma injuries was in May (13%). Over one-third of patients with traumatic injuries to permanent teeth (n = 218, 35%) injured 2 permanent teeth. The most commonly affected teeth were the maxillary central incisors (59.3%). The most common type of trauma was concussion (20.4%). There was statistically significant difference among the type composition ratio of age groups (P < .05). The most common causes of dental trauma were falls (50.2%). There was statistically significant difference among the etiological composition ratio of age groups (P < .05). Combined injuries were present in 120 teeth in 103 patients (16.5%). The epidemiological characteristics of dental trauma in Xi'an shows that the occurrence of dental trauma is closely related to the age, sex, time, type of injury, and cause of injury. There exists cross-correlation among the epidemiological factors. The most common type of trauma is concussion and the most common cause of dental trauma is fall. High incidence of combined injuries needs extra attention.
创伤性牙损伤是急诊科常见的损伤之一。为了确定西安急诊创伤性牙损伤的分布特征，根据年龄、性别、病因、易伤牙因素和损伤牙类型，对 623 例（6-78 岁）患者的病历资料进行了评估和分析。患者中男 397 例（63.7%），女 226 例（36.3%），男女比为 1.8:1。共损伤牙 1475 颗。牙外伤发生率最高的年龄组为 19-30 岁（30.7%）。牙外伤发生率最高的月份为 5 月（13%）。超过三分之一（n=218，35%）的恒牙创伤患者损伤了 2 颗恒牙。最常受伤的牙齿是上颌中切牙（59.3%）。最常见的创伤类型是震荡（20.4%）。各年龄组间牙外伤类型构成比差异有统计学意义（P<.05）。最常见的牙外伤原因是跌倒（50.2%）。各年龄组间病因构成比差异有统计学意义（P<.05）。103 例患者的 120 颗牙合并损伤（16.5%）。西安牙外伤的流行病学特征表明，牙外伤的发生与年龄、性别、时间、损伤类型和致伤原因密切相关。这些流行病学因素之间存在相互关联。最常见的创伤类型是震荡，最常见的牙外伤原因是跌倒。合并损伤发生率较高，需要特别关注。
