Abstract

Objectives: To determine the frequency of traumatic dental injuries according to Andreasen classification in children from 1 to 15 years old, treated in the Pediatric Dentistry Service of the Peruvian University Cayetano Heredia Teaching Dental Center, from January 2012 through October 2017. Material and methods: This study was descriptive and retrospective. Samples were composed of clinical records from patients with traumatic dental injuries who accomplished the inclusion and exclusion criteria. The evaluated variables were: types of traumatic dental injuries, sex, age of the patient, place, cause of the trauma and type of teeth affects. Results: A total of 9880 medical records were found, of which 1.18% (n = 117) represent patients who presented traumatic dental injuries. From these, 73 were from boys and 31 from girls, who had an average age of 4.36 ± 3.42 years old. Conclusions: Injuries to the periodontal tissue and injures to gingiva and/or mucosa were the most common injuries on both dentitions. Games were the most frequent cause for traumatic dental injuries, home was the most frequent place for primary dentition and school for the permanent dentition. Two year-old patients were the most affected in primary dentition and seven year-old patients in permament dentition.
