The aim of the present study was to explore the epidemiological characteristics and treatment of traumatic dental injuries of primary dentition (TDI-p) in Xi’an, China.
Material and methods
Data of children with TDI-p admitted between January 2018 and December 2019 at the Department of Pediatric Dentistry, Xi’an Jiaotong University Stomatology Hospital were retrospectively analysed. The epidemiological distribution characteristics and related treatment information of TDI-p were described.
A total of 696 children (male-to-female ratio, 1.7: 1) with 1241 traumatised primary teeth were analysed. The peak period of TDI-p was 2 to 3 years of age (24.7%). TDI-p often involves a single tooth (46.3%), and the maxillary central incisors (75.4%) were the most frequently affected. About 57.6% of patients sought dental treatment within 1 day to 1 week after injury. Among the various types of teeth injuries, concussion (16.9%), subluxation (13.2%), and root fracture (13.3%) were the most common types of TDI-p. In addition, combined traumas mainly manifested as enamel-dentin fracture combined with a concussion (35.3%) or subluxation (23.3%). The recurrence rate of TDI-p was 3.3%. Observation (42.6%) and extraction (28.2%) were the most common ways to deal with TDI-p. About 46.6% of the children received treatment under physical restraints or general anaesthesia. About 3.3% of the guardians had a negative attitude towards the treatment plan or behavioural management of TDI-p.
Compared with permanent dentition, TDI-p has its particularities, such as type of trauma, treatment procedure, and behavioural management. More attention should be paid to TDI-p by both dentists and guardians.
