The mandible or lower jaw is the most frequently fractured bone because of the mandible's prominence and relative lack of support. Literature data differ considerably with respect to the epidemiology and etiopathogeny of mandibular fractures. The aim of this study is to evidence the incidence of mandibular fractures depending on sex, age and etiology in a significant group of patients. Materials and methods: For the current study, a 10-year retrospective evaluation of cases diagnosed with mandibular fractures in the period 1 January 2002 – 31 December 2011 at the Clinic of Oral and Maxillofacial Surgery I Cluj-Napoca was performed. Data were collected from clinical observation charts, processed and compared to literature results. Results: The study included 709 patients. The highest incidence of mandibular fractures was found in the 20-29 year age group (37.24%). Most of the patients were male (92.81%) and came from an urban environment (54.58%).

The most frequent cause of mandibular fractures was interpersonal violence (67.28%), followed by falls from the same level. Conclusions: Taking measures to reduce interpersonal violence would significantly decrease the incidence of mandibular fractures in our geographic area.
