Abstract

Cone beam computed tomography was a precise 3D imaging device designed for oral-maxillo-facial medicine. It permitted multiplane reconstructions, including coronal, sagittal and axial planes, definitely capable of improving the diagnosis and treatment of oral medicine. Compared with the traditional multi-slice computed tomography, cone beam computed tomography has the advantages of high image resolution, rapid scan, low radiation and small size. In forensic personal identification, 3D images of human tissues and organs acquired by cone beam computed tomography were valuable. Individual differences of the teeth were observed through cone beam computed tomography scanning, as well as the age related changes of dental pulp cavity. Mandibular canal images obtained by cone beam computed tomography could distinguish sexual dimorphism. Besides, the 3D reconstructions of the frontal sinus and craniofacial tissues supply a new method in anthropometry and facial reconstruction. In trauma analysis, cone beam computed tomography was an improved tool for the evaluation of bite marks, gunshot injuries, causes of fractures and stab wounds. Cone beam computed tomography could identify structural damages of hard tissues and detect the precise location of a projectile in the body. Virtual autopsy based on computed tomography has become a routine technology in the forensic practice of certain kinds of death. Cone beam computed tomography could supply higher quality images of the maxillofacial hard tissues. Progress in the research of cone beam computed tomography may improve the development of forensic odontology. In this article, some papers published in recent years were reviewed to show the present applications of cone beam computed tomography in forensic medicine, with purpose to provide new ideas for related research and practice.
