Objective. Carotid stenoses >= 50% are associated with increased risk for stroke that can be reduced by prophylactic carotid endarterectomy (CEA). Calcifications in arteries can be detected in panoramic radiographs (PRs). In a cross-sectional study, we analyzed (1) extirpated plaques for calcification, (2) how often PRs disclosed calcified plaques, (3) how often patients with stenoses >= 50% presented calcifications in PRs, and (4) the additional value of frontal radiographs (FRs). Study Design. Patients (n = 100) with carotid stenosis >= 50% were examined with PRs and FRs before CEA. Extirpated carotid plaques were radiographically examined (n 101). Results. It was found that 100 of 101 (99%) extirpated plaques were calcified, of which 75 of 100 (75%) were detected in PRs; 84 of 100 (84%) patients presented carotid calcifications in the PRs, in 9.5% contralateral to the stenosis >= 50%. Conclusions. Carotid calcifications are seen in PRs in 84% of patients with carotid stenosis >= 50%, independent of gender. FRs do not contribute significantly to this identification.
