BORIN-MOURA, Lucas et al. A 10-year retrospective study of dental trauma in permanent dentition. Rev Esp Cirug Oral y Maxilofac [online]. 2018, vol.40, n.2, pp.65-70. ISSN 2173-9161.


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).


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.


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.
