Abstract

The aim of the present cross-sectional survey was to assess factors associated with non-accidental collision followed by dental trauma among adolescents in the city of Diamantina, Brazil. A total of 387 students from 12 to 15 years of age (mean = 14 SD = 0.9) were randomly selected. The study was carried out in two stages. Firstly, data were collected through dental examinations of permanent incisors. Secondly, a thorough interview was held with 85 adolescents who exhibited dental trauma in the dental examinations. The interview consisted of a detailed description of the incident and physical environment in which it occurred. Descriptive analysis and the chi-square test (P < 0.05) were performed. The prevalence of dental injury was 22% (n = 85). Dental trauma was more prevalent in boys (P = 0.001) and individuals with overjet >3 mm (P = 0.007) and inadequate lip coverage (P = 0.013). Analysis of the event revealed that 22.3% of the cases of dental trauma occurred because of non-accidental collision. Non-accidental collision followed by injury occurred mainly at school (P < 0.001) and in an environment with a concrete, tiled or ceramic floor (P = 0.001). No statistically significant associations were found between non-accidental collision and gender, age or mother's schooling. It was concluded that the non-accidental collisions happened especially at school and in indoor environments with a concrete, tiled or ceramic floor.
