Abstract

Introduction

The aim of the study was to analyze the incidence, characteristics, and correlations between maxillofacial fractures and dental injuries in patients who were treated at a first-level trauma center in a metropolitan center in northwest Italy in the last 11 years.

Material and methods

Between January 1, 2001 and December 31, 2011, 2,110 patients with maxillofacial fractures were admitted. Only dentulous patients with complete clinical records who presented with associated dental injuries were included in this study. Data on the age, gender, mechanism of injury, damaged tooth, type of dental injury, site of facial fractures, and concomitant injuries were recorded.

Results

On the whole, 267 patients (13.1 %), mainly males aged 20–29 years, presented with 759 dental injuries associated with maxillofacial fractures, especially following motor vehicle accidents. The maxillary teeth, most often the anterior elements with decreasing involvement from the incisors to the molars, were the teeth most frequently damaged overall. The main types of dental trauma in patients with maxillofacial fractures were luxations and dental fractures.

Discussion

Our findings show that patients with mandibular fractures were statistically and significantly associated with dental injury, and the teeth in the upper jaw were the most frequently injured teeth, exhibiting mainly luxations and crown fractures. Confirmation of the predominant impact site in patients with dental injuries associated with maxillofacial fractures comes from the 177 lacerations noted in the chin and lip regions in 267 patients.
