Abstract Objective:

To identify the prevalence of maxillofacial injuries resulting from interpersonal violence in Brazilian children and adolescents.

Material and Methods:

This is a retrospective study conducted at a Center of Forensic Medicine and Forensic Dentistry with a sample of 335 medical reports of victims aged up to 19 years. Variables involved sex and age group, perpetrator, occurrence of the event, characterization of injuries, presence of maxillofacial injuries, type of tissue involvement, and injuries in the oral cavity. Data were analyzed using descriptive, and the Chi-square was used for categorical data.

Results:

Most victims were female (60.3%) and aged 15-19 years (57.6%). Aggressions occurred at home (50.6%), in the evening (39.5%) and involved perpetrators known to the victim (91.5%). Most victims had multiple injuries (75.8%), involving up to three regions of the body (93.4%). Injuries with blunt objects were the most frequent (86.2%). The prevalence of maxillofacial injuries was 36.7%, with low involvement of the oral cavity (8.4%). A significant association between the presence of injuries on the face and variables "perpetrator" (p=0.015) and "number of injuries" (p=0.006) was observed.

Conclusion:

Female adolescents were the main victims of physical violence, with repercussions in different regions of the body. The prevalence of maxillofacial injuries was high, although with little involvement of oral cavity structures.
