History

History: A 47-year-old woman visited the dentist concerning the extraction of tooth #32, which was causing her discomfort. The dentist ordered a cone-beam computed tomography (CBCT) scan to evaluate the impacted tooth.

The patient’s past medical history was remarkable for hypertension, which was well controlled with nifedipine.

The extraoral exam was within normal limits, while the intraoral exam revealed generalized gingivitis.

The dentist ordered a CBCT scan to evaluate the third molar. The dentist evaluated the images available and noted a lesion between teeth #28 and #29. Images are provided in the following order (click to enlarge):

• A reformatted panoramic film
• CBCT, coronal view
• CBCT, sagittal view
• CBCT, axial view
