[Soft tissue calcifications in panoramic radiography. A risk factor for cerebrovascular accidents?].
Panoramic radiography is a basic diagnostic tool in the dental field where calcifications are seen occasionally in the lateral parts of the x-ray. The differential diagnosis are carotid artery atheromas, calcified submandibular lymphnodes and sialoliths of the submandibular gland. 4007 panoramic radiographs (100%) from patients >40 years were scanned retrospectively. Special emphasis was given to the carotid artery territory (CAT). 225 soft tissue calcifications were found (5.6%). 144 patients had calcifications in the CAT (3.6%), 73 showed calcified submandibular lymphnodes (1.8%), and 8 (0.2%) sialoliths. The female to male ratio was 54.7%:45.3%. Pneumatic diseases were beside hypertension and smoking a risk factor for CAT calcification. Carotid artery atheromas are the main risk for cerebrovascular insults. Dentists can help to detect patients at risk for stroke. Their patients can be referred for further diagnostics (ultrasound).
