Applications of cone-beam computed tomography in dentistry

Abstract

Cone-beam computed tomography (cone-beam CT) is one of extraoral radiographic techniques which have been designed for
demonstrating hard tissue of maxillofacial region. It is capable of providing high quality image that increases diagnostic efficacy of
dentists with short scanning times and small radiation dosages reportedly up to 15 times lower than those of conventional CT scans that used in medical. Increasing availability of this technology provides the dentists with an imaging modality capable of providing a
3-dimensional representation of maxillofacial structures or lesions, minimal image distortion, which not found in conventional
radiographic techniques. Clinical applications of cone-beam CT in dental practice such as oral surgery, dental implant, maxillofacial
pathology, temporomandibular joint disorders. However, cone-beam CT has limitation of evaluating soft tissue that needed further
investigation for advance development of the machine and software program.
