Radiology is an essential aid to the diagnosis, treatment planning and monitoring of oral diseases. Advances in imaging technology have revolutionized our ability to study image and understand pathology on a macroscopic level. Digital radiology is the next step in the evolution of radiology, its features like significant reduction in radiation exposure, the ability to digitally manipulate the captured image to produce a more diagnostic image, reduction in time between exposure and image interpretation, and digital documentation of patient’s records make it a valuable diagnostic aid in hands of a clinician. New diagnostic modalities, like computed tomography has revolutionized dental diagnosis by multi planar reconstructions and allowing virtually any view to be selected, making three dimensional imaging possible by a few clicks on the computer. Hence; we aim to summarize some of the important aspects of role of Computed tomography in jaw lesions.
