Abstract

This review provides an overview of the relevance of imaging techniques such as, computed tomography, cone beam computed tomography, and ultrasound, to endodontic practice. Many limitations of the conventional radiographic techniques have been overcome by the newer methods. Advantages and disadvantages of various imaging techniques in endodontic practice are also discussed.

Keywords: Computed tomography; cone beam computed tomography; cone beam volumetric tomography; endodontics; radiovisiography; ultrasound.
