This study characterized the dental and maxillofacial injuries in hard and soft tissues in a cohort of severe trauma patients. Used the prospective registry of trauma patients that uses TRISS methodology for severity analysis. Inclusion criterion was the presence of anatomical lesion in the face, using the Abbreviated Injury Scale due to road traffic accident and work-related accidents. The study was complemented with the patient's registries and 6 months follow-up. Between 2002 and 2005 were admitted to the Emergency Room of Santo Antonio General Hospital, 868 severe trauma patients. 151 had lesions on the face due to traffic accident (92%) and accidents at work (8%). A total of 85% was males, and the age group 15–19 years of age dominated (18%). 37% of lesions were located in the soft tissues and the region most affected was the right orbit (14%). The region most affected in the hard tissue was the nasal (28%). The records of injuries from the clinical prospective data through observation of patients in follow-up show that the main dental and maxillofacial trauma is of little importance in the initial evaluation of the patient.
