Cone beam computed tomography: Adding three dimensions to endodontics

The need for evaluating the structures in three dimensions led to the revolutionary invention of cone beam computed tomography (CBCT). CBCT had found its application in various regions of dentistry. The literature demonstrates the use of CBCT for specifi c endodontic applications. The purpose of this article is to review the history and evolution of CBCT, its advantages over conventional radiography and to discuss the literature validating its application in endodontics.
