Actual (reported)The odontological radiology method Panorama is known to be able to spot calcifications in the area of the carotid arteries. The calcifications could be carotid stenoses which is affiliated with an increased risk of stroke. The study aims to investigate if panorama examinations can be used as a starting point for further investigation of the carotid arteries.

Actual (reported)The prevalence of carotid stenosis in the group that is examined with carotid ultrasound on the "atheroma on Panoramic examination"-indication
100 asymptotic patients that have findings of calcifications in the area of the carotid arteries when examined with panorama. These persons are examined with carotid ultrasound.
100 patients with a known carotid stenosis seen on ultrasound will be examined with panorama before any intervention is made. These patients must undergo surgery to be finally included.
Ultrasonographic examination of the carotid arteries to determine the grade of carotid stenosis.
Examination with the odontological radiological method "Panorama", including a frontal verification image
