Few technological advances in dentistry have been as influential as the innovation of cone-beam computed tomography (CBCT). Similar to a medical CT unit found in a hospital, a CBCT is essentially a 3-dimensional x-ray that can be used for improved diagnosis and treatment. When used appropriately, it can greatly enhance the diagnosis and treatment planning of a variety of endodontic cases. However, it is important that each case is considered individually to ensure that the benefits provided by the scan outweigh the risks of the additional radiation. Three-dimensional imaging is proven to ensure more accurate diagnosis and therefore improved management of complex endodontic cases and so to rapidly influence the assessment of complex root canal anatomy, periapical periodontitis, root resorption, dental traumas and root fractures. Cone-beam computed tomography can be a powerful tool in endodontic treatment planning, assessing the outcome of the root canal treatment and follow-ups. That is the reason for the rapid increase of the use of cone beam computed tomography in the field of endodontics worldwide.
