Oral injuries are fourth most common area of bodily injuries among 7-30 year-old individuals. Involvement of children in sports activities and increase in traffic accidents have contributed to transform these TDI an emergent public health problem. Aim and Objectives: The current retrospective study is to determine the prevalence of TDI reported to Dental Department at Darbhanga Medical College and Hospitals, during the years 2016–2017. Methodology: Sample size is the total number of patients reported to the Dental Department at Darbhanga Medical College and Hospitals, within the period of 2016–2017. The data were retrieved from records of patients who reported to the department. Results: All recorded data were analyzed using the Statistical Package for the Social Sciences statistical software program (2012). The results were evaluated by Chi-square test. A total of 424 patients aged between 3 and 18 years met the inclusion criteria and were enrolled in the study. The highest frequency of TDI was in the 10–12yearold participants and lowest frequency was in 3–6yearold children. The etiology of TDI was analyzed, highest were caused by falls followed by sports activities and then striking objectives and then followed by accidents and cycling. The most common type of injury was uncomplicated crown fracture (without pulp exposure) followed by avulsion and complicated crown fracture (with pulp exposure). Conclusion: Study observed the children in mixed dentition period as the population at risk. Hence, prevention through health promotion and correction of predisposing risk factors should be carried out in early mixed dentition period to reduce the prevalence of dental injury and to avoid the financial costs of treatment.
