Cone-beam Computed Tomography?A New Vision in Endodontics-A Review

The discovery of X-Rays was done by Roentgen in 1895, since then the dental radiography has extensively played an appealing and analytical diagnostic role in dentistry. The management of endodontic complications is truly dependent on dental radiographs to evaluate the anatomy of the respected tooth and its surrounding structures. The key to success in the management of endodontic complications intensely depends upon the diagnostic imaging procedures to deliver the analytical information related to the teeth under consideration and their surrounding anatomy. Though, many of these images may have certain limitations and drawbacks. Recent advancements in the field of radiography have been introduced such as computerized tomography scans, magnetic resonance imaging, ultrasonography, and several imaging techniques that have been transformed diagnosis in the medical and dental field. Primary computerized tomography scans which are used in medical diagnosis are called Medical Computerized Tomography whereas the newer technique used considerably in the field of dentistry is called Cone Beam Computed Tomography (CBCT). The usage of Cone-beam computed tomographic imaging for analysis and management of endodontic complications is rapidly being employed in the field of dentistry. It is useful to detect several endodontic conditions like vertical root fracture, root resorption, to obtain detailed knowledge about the anatomy of the root canal. The usage of cone-beam computed tomographic imaging technique is highly recommended in the situation of missed canals and calcified canals. It can be used in all stages of treatment from preoperative to postoperative assessment and follow-up. The CBCT imaging is considered in those conditions where no adequate data is obtained from conventional radiographic techniques.
