New dimension in endodontic imaging – cone beam computed tomography

Cone beam computed tomography (CBCT) has proven to be an important as well as essential tool for successful diagnosis, treatment planning as well as post procedure monitoring in all fields of dentistry including endodontics. It is a modern, radiological imaging system which is designed so as to produce undistorted three-dimensional image of the maxillofacial skeleton, teeth and the surrounding tissues that overcomes the limitations of conventional radiograph. CBCT allows as well as confirms a more precise and accurate diagnosis of any periapical lesions (true size, extent, nature and position), root fractures(specially vertical), root canal anatomy(location and number of canals, pulp chamber size, direction and curvature of root morphology), true nature of the alveolar bone topography around teeth, external and internal resorptions, degree of calcification, inflammatory lesions and defects. The relationship of anatomical structures such as the maxillary sinus and inferior dental nerve to the root apices may also be clearly visualized. The purpose of this article is to assess the functionality of CBCT as a high resolution imaging technique and its potential Implementations in the diagnosis and treatment of various endodontic conditions.
