Objective:

This study aims to identify the characteristics and factors associated with TDI treated at a referral service.

Material and methods:

A ten-year period cross-sectional retrospective analysis of medical records of patients with TDI in their permanent teeth was performed, and injury-related data were collected. Statistical analysis was performed using the chi-square association test and complex analysis (p < 0.05).

Results:

Records of 545 patients, totaling 1438 traumatized teeth, were evaluated, and a male prevalence at a 2.4:1 ratio was found. The age group with highest incidence was 13-19 years. Central maxillary incisors and dislocations were the most affected teeth and TDI, respectively. Statistical analysis showed different TDI causes according to age: children are often victims of falls, traffic accidents, aggression and collisions, whereas adolescents are involved in sports accidents, and young adults in traffic accidents, falls and collisions.

Conclusion:

Considering the scope of this retrospective study at a single referral center, a profile of young male patients with TDI in superior central incisors due to falls, collisions, traffic accidents or sports could be detected.
