Use of Cone Beam Computed Tomography in Endodontics

This patient was referred for discomfort and swelling in the maxillary right quadrant. While an initial periapical radiograph (a) clearly demonstrated an untreated mesial root in the maxillary first molar, periradicular periodontitis was undetectable. CBCT images ((a) axial, (b) sagittal) clearly identify a large apical radiolucent lesion associated with the mesial root extending to the distobuccal root. The tooth was retreated and the symptoms subsided.
