Abstract

Clinical examination and diagnostic techniques are principal components of preoperative diagnosis and treatment plans in endodontics. This article reviewed the role of cone beam computed tomography in the diagnosis and management planning in endodontics. The study included studies that are in accordance with the review subject with an appropriate explaining and suggested opinion of the author. In spite of the popular and common use of the conventional two-dimensional radiographic imaging, the diagnostic accuracy of periapical radiographs is still questionable, especially in positions with complex anatomical pattern. Low radiation dose, cost, availability, shorter scanning time, better resolution and easier image interpretation as compared to tradition conventional tomography make it more favorable in the endodontic field. Cone beam computed tomography has been used in detection of periapical lesion, assessment of the outcome of root canal treatment, for presurgical assessment, detection of apical periodontitis and identification of affected roots, root resorption, assessment of root canal anatomy, assessment of dental trauma and vertical root fracture. It is now considered a desirable additive tool to endodontist’s field of work. However, it should not be used as a routine. For the purpose of deciding whether to use or not to use this smart scan, the benefit must outweigh the possible risks of radiation exposure, especially among children.
