Objective: The objective of this study was to determine the prevalence of traumatic dental injuries (TDIs) in the anterior teeth among children attending paramilitary and nonparamilitary schools in Benin City, Nigeria. Materials and Methods: A multistage sampling technique was used to select children aged 8–12 years with a previous history of trauma to the orofacial region. A self-administered questionnaire was then applied, and each participant was examined clinically. Data collected included demographic characteristics, etiology and place of injury, affected teeth, type of dental injury, lip competence, and overjet values. Analysis of data was done with the SPSS version 21.0 software. Pearson's Chi-squared test was used to determine the association between variables and odds ratio. Statistical significance was determined at P < 0.05. Results: A total number of 1352 children (mean age: 9.89 ± 1.4 years) were examined and 154 (11.4%) had a previous history of TDI. The prevalence among respondents in the paramilitary schools was 84 (6.2%) and those in nonparamilitary schools 70 (5.2%). Falls and play was the most common cause of TDI and was higher in children in paramilitary schools. Ellis Class I was the most prevalent type of injury in 91 (59.1%), tooth number 21 was the most traumatized, and the school environment was the most common place. Of the total number of respondents with TDI, the relationship between etiology with age, lip competence, and overjet was statistically significant (P < 0.05). Conclusion: The prevalence of TDI among the study participants was 11.4% and more in the paramilitary schools than the nonparamilitary.
