Abstract

The mandible is the largest and only moveable facial bone. It begins as 2 separate
bones and unites anteriorly when a child approaches 1 year of age. Being a prominent bone of the facial skeleton, it is fractured most commonly among maxillofacial injuries.
This epidemiological study was conducted to evaluate the etiology of mandibular fractures and anatomical site of the fracture in 115 patients treated in the Department of Oral and Maxillofacial department ALZhraa hospital in ALKut city from 2012 to 2014. These patients were examined both clinically and radio-graphically for mandibular fractures. Records related to age, sex, and etiologies of fracture and sites of fracture were evaluated and reviewed. The most common age group affected was 21-30 years (26,08% ). Only 17.39% of patients were less than 10 years of age, and 1.7% was more than 60 years of age. Male to female ratio was 4:1. The most common cause of mandibular fractures was road traffic accidents (52.1%) followed by accidental fall (26.08%), while the least involved group was industrial accidents (1.7%), A total of 146 fractures were sustained by 115 patients at different sites there were multipl fractures in the same person .The most common site of mandibular fracture was parasymphysis (30.43%). All over the world, mandibular fractures have continued to generate discussion among researcher due to their important fuction .The male to female ratio shows 4:1 this is also in agreement with most of the studies due to their freqent participation in high risk activity such as driving vehicles sport that involve physical and active social life .
