Abstract
Cone beam computed tomography is an extraoral radiography. The cone beam computed tomography radiograph demonstrates the relationship of interested tissue in all three planes and can be reformatted image in three dimensions, which could not be done by other conventional radiographs. This imaging modality is very useful in many dental diagnoses and treatment plannings, for example, dental implant, oral surgery and diagnosis of pathology of the temporomandibular joint and the jaw bone. A cone beam computed tomography machine has been developed by many companies. Each machine has a different specification, but all can be controlled by computer system. Using this system, the image acquisition is done in a short time. However, cone beam computed tomography has the limitation of soft tissue lesion scanning and it produces a relatively high radiation dose to the patient as compared to a conventional radiograph. Therefore, appropriate selection of the patient for using cone beam computed tomography for each patient should be considered.
