The role of panoramic radiographs in the medical surveillance of a patient at risk for stroke: case report.

Positive carotid calcifications on a panoramic radiograph were found to be in agreement with significant carotid stenosis as determined by duplex ultrasound examination. As dentists are expected to be aware of systemic health conditions that they identify while providing dental care and to refer patients for follow-up medical care, this case report may help dentists to detect incidental carotid artery calcifications on panoramic radiographs.
