Abstract

The use of cone beam computed tomography (CBCT) in endodontics has expanded in recent years. 3D imaging adequately supports the interpretation of dental anatomy and surrounding areas during root canal therapy. To assist decision making in endodontic cases, experts recommend small field-of-view (FOV), high-resolution CBCT imaging for diagnostic and treatment planning as well as for intraoperative procedures and managing cases post-treatment. This article presents some examples of everyday clinical cases to illustrate how CBCT images can help diagnose, treat, and solve endodontic problems.
