Diagnosis and treatment of complex endodontic retreatment cases require precision to remedy what was done previously. A conventional periapical X-ray has an apparent disadvantage: it creates only two-dimensional images, which in turn hide the complexities of root canal morphology, potential mishaps such as missed canals, perforations, and vertical root fractures. Owing to its ability to provide three-dimensional views of root canal systems and periapical structures, it has now found widespread use as an adjunctive diagnostic tool. Reports published up to February 2020 give a strong indication that CBCT enabled the better detection of untreated anatomy, periapical lesions, and iatrogenic complications, which they also suggest improves retreatment outcome. Even though it comes with some risks such as radiation exposure and metal artefacts, CBCT is now acknowledged as a must-have tool in modern cases of retreatment especially when conventional imaging fails to provide a clear picture.
