[Retrospective analysis of 956 cases with dental trauma].

Abstract

Purpose: To find the clinical characteristics of permanent teeth trauma among young and adult people in Shanghai Ninth People's Hospital, and provide reference for the treatment and prevention of dental trauma among them.

Methods: The data of 956 patients who visited the Dental Trauma Clinic of Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine from September 2021 to March 2023 were collected and analyzed according to age, gender, occupation, causes of trauma, types of tooth injuries, number and position of affected teeth, time to seek treatment after injury, and whether the patients had been exposed to popular science knowledge related to tooth trauma.

Results: The male to female ratio of dental trauma patients was 0.93∶1. The tooth position with the highest incidence of dental trauma was the maxillary central incisor, followed by the maxillary lateral incisor. Subluxation and uncomplicated crown fractures were the subcategories with the highest incidence of dental trauma. For the post-traumatic treatment time, 55.54% of patients sought medical consultation within 1-4 hours. Survey of the occupation of patients with dental trauma found that high-risk exposure accounted for only 7%. Among them, the highest risk occupation were builders and men for takeaway. Falls and traffic accidents were the main causes of dental trauma. Only 8% of the patients received scientific knowledge related to dental trauma.

Conclusions: Tooth injuries are more common in the upper incisors, and the types of injuries are more common in crown fractures and subluxations. The main causes are falls and traffic accidents. Dentists should strengthen the popularization of knowledge about dental trauma, and the public should pay attention to strengthening the rational use of mobile phones, raising road safety awareness, and learning emergency treatment methods for dental trauma.
