Biomedica Jan ;33(4):296-9.

Background and Objective: The aim of this study was to determine the pattern and causes of traumatic dental injuries (TDI?s) to permanent teeth in children of age 7 to 14 years. Methods: An analytical cross sectional study was carried out from July 2016 to June 2017. A total of 79 injured teeth in 58 patients were included in this study. The Federation Dentaire Internationale System of tooth numbering and Ellis?s classification of traumatic dental injuries (TDI?s) was used for teeth fractures. Kruskal-Wallis and Mann?Whitney U tests were used to assess pattern of injury and type of teeth involved. P value ? 0.05 was considered significant. Results: Boys had more injuries as compared to girls with ratio of 1.4:1. The most frequent age involved was 12 years. Amongst causes; fall was the most common cause (39.24%) followed by accident (24.05%) and bicycle (17.72%). The most prevalent tooth involved was right maxillary central incisor n = 26 (32.91%, p = 0.001) and Ellis?s classification III (37.97%, p = .001) of teeth fracture was common. Conclusion: The study concluded that the most frequent cause was fall and right central incisor and Elis?s II classification were the most common amongst traumatic dental injuries.
