Abstract
Dentoalveolar trauma may occur after accidental falls, automotive accidents, violence, or contact sport injuries. This study aimed to investigate the prevalence of dentoalveolar and maxillofacial fractures with multidetector-row computed tomography (MDCT). Forty patients with dentoalveolar and maxillofacial fractures underwent MDCT. Mandibular fractures were classified into four types: median, paramedian, angle and condylar types. Midface fractures were classified into four types: Le Fort I-III and zygomatic maxillary complex types. Statistical analysis of the relationship between prevalence of dentoalveolar fractures and maxillofacial fracture locations was performed using Chi-square test with Fisher's exact test. A p-value less than 0.05 was considered statistically significant. The prevalence of dentoalveolar fractures was 15.0% (6/40 cases) of all patients with maxillofacial fractures. The mean age of patients with and without dentoalveolar fractures in maxillofacial fractures were 39.8 years and 54.7 years, respectively. Regarding cause of injury, the prevalence of maxillofacial fractures with dentoalveolar fractures were 18.8% of accidental falls and 0% of contact sport injuries and automotive accidents. There was no significant relationship between prevalence of dentoalveolar and maxillofacial fractures. The results suggest that the prevalence of dentoalveolar and maxillofacial fractures are related to the age and cause of injury.
