This study aims to investigate the clinical visiting and prognosis of schoolchildren in Xi'an after immature permanent tooth trauma and explore the prognostic factors associated with this type of trauma.
Through cluster and simple random sampling surveys, 4 013 pupils in schools from nine districts and four counties in Xi'an were sampled, respectively. All pupils and their parents were requested to complete a questionnaire, and children who had immature permanent tooth trauma answered a separate questionnaire and underwent oral examinations. The data of the survey were analyzed statistically.
The amount of valid questionnaire was 3 641. Clinical visiting rate related to immature permanent tooth trauma of Xi'an schoolchildren was low (38.2%). Gender and trauma type were the factors related to clinical visiting for dental trauma concerns. The incidence of poor prognosis was 29.7%. The incidence of poor prognosis of patients with clinical visiting (35.4%) was higher than that of patients without clinical visiting (20.6%).
Clinical visiting rate related to immature permanent tooth trauma in Xi'an schoolchildren is extremely low, and incidence of poor prognosis is high.
本研究旨在调查西安学龄儿童恒牙未成熟外伤后的临床就诊情况及预后，并探讨与此类外伤相关的预后因素。
通过整群和单纯随机抽样调查，分别抽取西安市九区四县学校的4013名小学生。要求所有学生及其家长填写问卷，有恒牙未成熟外伤的儿童填写单独问卷并接受口腔检查。对调查数据进行统计学分析。
有效问卷数量为3641份。西安学龄儿童恒牙未成熟外伤的临床就诊率较低（38.2%）。性别和外伤类型是与牙外伤就诊相关的因素。预后不良的发生率为29.7%。有临床就诊的患者预后不良发生率（35.4%）高于无临床就诊的患者（20.6%）。
西安学龄儿童恒牙未成熟外伤的临床就诊率极低，预后不良发生率较高。
