Objective To explore the epidemiological characteristics of primary and secondary dental trauma and to provide health education for the prevention and self-help of dental trauma. Methods A retrospective analysis was conducted on the traumatic anterior teeth injuries of primary and secondary school students from January 2012 to December 2014 in our hospital emergency department. The causes of dental trauma, the incidence of tooth injury, the mode of injury and the time of trauma after trauma were discussed. Results The ratio of male to female in 134 cases of dental trauma was 1.7:1, and the rate of diagnosis was 89.7% in 24 hours. The trauma of the maxillary anterior teeth was significantly higher than that of the mandibular anterior teeth. The incidence of dental trauma in 6-12 years old group was significantly higher than that of the middle school students. Conclusion Oral health education of dental trauma should be carried out as soon as possible in schools and the correct protective measures should be trained to improve the self-help ability and good prognosis of dental trauma.
