Radiographic imaging is a primary and most essential step in the diagnosis, treatment planning and assessing the treatment outcomes of all the cases in endodontics. There are several confounding factors like regional anatomy and superimposition of the teeth and adjacent dentoalveolar structures that influence the interpretation of an image. Due to the complex maxillofacial skeleton, conventional two-dimensional (2-D) radiographic images fail to provide accurate information. The structures so visualized are also subject to geometric distortion. Since untreated anatomy has been documented as a significant cause of endodontic failure. Hence, recent research has highlighted the need for 3-D imaging modality to be used as an adjunct to overcome the potential drawbacks of 2D radiography in assessing the root canal anatomy.
