Abstract

Background: The facial skeleton is a complex structure composed of five paired bones and four unpaired bones, with mandible fractures being among the most common injuries encountered in trauma centers. Panoramic imaging, also known as pan tomography (OPG), is a technique that provides a single, wide-view image of the facial structures.

Methods: The study was a descriptive cross-sectional study which was carried out from 16 August 2016 to 16 May 2017 in the Department of Oral and Maxillofacial Surgery, Dental Wing, Combined Military Hospital, Dhaka and Dhaka Dental College and Hospital. A total 40 patients having mandibular fracture were included in this study and were evaluated radiologically by both conventional radiography (orthopantomography) and cone beam computed tomography (CBCT).

Results: Among the 40 cases the mean age for the male patient with mandibular fracture were 25.16 ± 2.7 and for the female patient it was 29.80 ± 5.0. Most cases were male than female, RTA was found the most common cause of fracture mandible. Most of the cases were associated with other body part injury excluding head injury. Most commonly fractured anatomic region of mandible was found angle 18 (45%) followed by body 16(40%). CBCT detected more fracture sites than Orthopantomograph.

Conclusion: CBCT was found more accurate than orthopantomography (OPG) in detecting fracture sites. Thus CBCT helped in early and proper management of fracture reduction and rehabilitation of the patients.
