The use of cone beam computed tomography in endodontic re-treatment

Abstract

Radiography plays an integral role in endodontics. However, conventional radiographic techniques have limitations, such as background noise, providing only a two-dimensional representation of the image, superimposition and distortion. Cone beam computed tomography (CBCT) provides the clinician with a three-dimensional image of the structures involved in the clinical situation. When considering options for endodontic re-treatments, it is vital to identify the cause of the initial failure and here, the use of CBCT images can be beneficial. This is illustrated through an endodontic re-treatment case owing to a palatal canal missed with conventional radiographic techniques. CPD/Clinical Relevance: Cone beam computed tomography can be beneficial in cases of endodontic re-treatment.
