Panoramic dental radiography: an aid in detecting individuals prone to stroke.
Stroke (cerebrovascular accident, CVA) is the third leading cause of death and an important cause of hospital admission and long-term disability in England and Wales. Atherosclerotic lesions at the bifurcation of the common carotid artery are the most common cause of stroke. On occasion, these lesions are partially calcified and visible on a conventional panoramic dental radiograph. The atheroma may appear either as a nodular radiopaque mass or as two radiopaque vertical lines within the soft tissues of the neck at the level of the lower margin of the third cervical vertebra (C3). These opacities are separate and distinct from the hyoid bone and variably appear above or below it. Dentists should scrupulously review the panoramic radiographs of all individuals over the age 55 with medical histories (hypertension, diabetes mellitus, hypercholesterolaemia, coronary artery disease) and behaviours (smoking, alcohol abuse, dietary indiscretion, overweight, sedentary life-style) known to be associated with atherosclerosis and stroke.
