Carotid artery calcification in ischemic stroke patients detected in standard dental panoramic radiographs - a preliminary study.
OBJECTIVE
Examine the prevalence of carotid artery calcifications in standard dental panoramic radiographs (OPT), their association to gender, medical history and oral status. Assess the predictive value of a dental OPT in early diagnosis of carotid artery calcifications.


METHODS
Fourteen patients admitted to Geneva University Hospital for recent ischemic stroke and stenosis of the carotid artery confirmed by Duplex sonography. All OPTs were digitised and subsequently assessed independently by two operators.


RESULTS
From 21 carotid artery calcifications detected with Doppler sonography 15 were visible on the corresponding OPT, most of them on the right side (n=11). No correlation was found between the side of calcification and cerebral lesion. Hypertension and periodontal disease were the most prevalent cardiovascular risk factors.


CONCLUSIONS
Dentists who either detect carotid artery calcifications in OPTs or see patients with severe periodontitis should consider a prophylactic specialist examination.
