Description

The discovery of X-rays, by Roentgen, revolutionized the way for 'looking inside' the body from outside. A complex and multisystem disease requires imaging support to confirm diagnosis. It provides to assess the extent of disease spread and staging. Imaging also permits an easy and non-invasive follow-up of patients and also just to document a known abnormality. Currently available high precision gadgets allow entry to surgically inaccessible areas. Another major advantage of these procedures are; these can be repeated many times, without any open surgery. Accurate oral diagnosis and treatment are very closely linked to the quality of dental radiographs. Dentistry has witnessed tremendous advances in all its branches over the past few decades. With the advancements in dentistry, the need for more precise diagnostic tools, specially imaging methods, have become mandatory ranges from the simple intra-oral periapical radiographs, advanced imaging techniques like computed tomography, cone beam computed tomography, magnetic resonance imaging and ultrasound.
