relationship between carotid artery calcification detected in dental panoramic images and hypertension and myocardial infarction

conclusions the relationship between cac found on dental panoramic radiographs and two cva risk factors--hypertension and mi-- was significant. therefore, it seems that detection of cac on panoramic images of dental patients must be considered by dentists. results among 200 studied samples, 22 of the patients (11%) had carotid artery calcification on the dental panoramic radiograph. in total, 52 patients (26%) had hypertension and four people (2%) had a history of mi. eleven individuals among patients suffering from hypertension (21.2%) and three individuals among patients with a history of mi (75%) demonstrated cac on dental panoramic images . patients and methods panoramic images of 200 patients that were all women above 50 years of age (a population suffering from vascular diseases) were investigated. all panoramic images were provided under similar conditions in terms of the type of panoramic radiograph equipment, type of applied films and the automatic film processor. then, the patients answered questions about mi history and taking antihypertensive drugs. we also measured the blood pressure of patients in two separate surveys. data analysis was performed by spss statistical program. we used exact fisher test and chi-square test at a significant level of less than 0.05 to study the effect of these variables on the occurrence of carotid artery calcification. background carotid artery calcification may be related to cerebrovascular accident, which may result in death or physical and mental disabilities in survivors. objectives our purpose is to study the association of carotid artery calcification (cac) on dental panoramic radiographs and two risk factors of cerebrovascular accident (cva) including hypertension and myocardial infarction (mi).
