Concomitant dental injuries in maxillofacial fractures - a retrospective analysis of 1219 patients.

Abstract

Traumatic dental injuries are frequently combined with maxillofacial fractures, but literature addressing this topic is rare. In a retrospective study, the frequency of dental lesions in inpatients with traumatic facial injuries was analyzed. All patients referred to the Department of Oral and Maxillofacial Surgery of the University Medical Center of the Johannes Gutenberg-University Mainz for inpatient treatment due to facial fractures between January 2001 and December 2007 were analyzed regarding the type of fracture, its localization, and potential concomitant dental injuries. In addition a systematic review was performed to compare the findings of this study with existing data. Altogether 1219 facial trauma patients underwent inpatient treatment. 184 (15.87%) out of those had 451 injured teeth, and 4.9% were edentulous. The most frequent causes were assaults (25.1%), followed by falls (19.6%) and bike accidents (10.1%). Avulsion, especially of the upper incisors, occurred in most cases (27.9%). Assaults caused 1.29 dental fractures per patient, while traffic-related accidents led to three to four times higher injury-rates. With almost every sixth patient having at least one kind of dental injury, this study shows that a thorough anamnesis and examination of the dental status are absolutely necessary, especially in patients who suffered from high-speed impacts or collisions with low-resilience surfaces.
