This review provides an overview of the relevance of imaging techniques such as computed tomography, cone beam computed tomography, and ultrasound, to the endodontic practise. An evidence-based approach to adoption of different imaging technologies is included to assist the practitioner with the selection process of imaging modalities. Commonly used imaging terminology is also been included, as well as the advantages and disadvantages of image processing. New image reconstruction techniques have been introduced that provide three-dimensional image to the clinician for routine endodontic and surgical treatment planning. Limitations and advantages of newly introduced imaging modalities are also discussed briefly.
