BACKGROUND AND AIMS
This study was designed to evaluate the prevalence of calcified carotid artery in 50 year-old and older postmenopausal dental outpatients for early diagnosis of individuals at risk of stroke.
MATERIALS AND METHODS
This is a descriptive study of 200 panoramic radiographs. These radiographs included post-menopausal women referring to the Department of Oral Medicine at Shahid Beheshti Faculty of Dentistry during 2006-2007. The x-ray machine, developer and film type were the same for all the radiographs. Statistical analysis included chi-square test and Fisher's exact test.
RESULTS
We found 22 calcified carotid arteries. The left and right carotid arteries were involved in 7 and 9 cases, respec-tively. In 6 cases both carotid arteries were calcified. Four individuals had no vascular risk factor excluding age and others had at least one risk factor. We found significant statistical correlation between hypertension, past history of myocardial infarction, and hypercholesterolemia with calcified carotid artery on panoramic radiographs.
CONCLUSION
Under the limitations of the present study, prevalence of calcified carotid arteries is 11.0 % in 50 year-old and older postmenopausal dental outpatients.
背景与目的
本研究旨在评估50岁及以上绝经后牙科门诊患者颈动脉钙化的患病率，以便对中风高危个体进行早期诊断。
材料与方法
这是一项对200张全景X线片的描述性研究。这些X线片包括2006年至2007年期间到沙希德·贝赫什提牙科学院口腔医学系就诊的绝经后女性。所有X线片使用的X线机、显影剂和胶片类型均相同。统计分析包括卡方检验和费舍尔精确检验。
结果
我们发现22例颈动脉钙化。左侧和右侧颈动脉钙化分别为7例和9例。6例双侧颈动脉均钙化。4例除年龄外无血管危险因素，其他患者至少有一项危险因素。我们发现高血压、心肌梗死病史和高胆固醇血症与全景X线片上的颈动脉钙化之间存在显著的统计学相关性。
结论
在本研究的局限性下，50岁及以上绝经后牙科门诊患者中颈动脉钙化的患病率为11.0%。
