全景牙科x光片常用于普通牙科和口腔颌面外科，同时检查上、下牙齿、上颌、下颌骨和周围环境。颈动脉钙化是颈动脉粥样硬化改变的具体指标，可以在x线片上看到。许多研究表明，吸烟是动脉粥样硬化改变和脑梗死的危险因素。我们假设吸烟会增加颈动脉钙化的患病率，并比较了50岁及以上吸烟者和不吸烟者的x线片：146名男性吸烟者，165名男性不吸烟者，42名女性吸烟者和422名女性不吸烟者。这是第一个关注颈动脉钙化的研究，通过全景牙科x光片显示吸烟与动脉粥样硬化变化之间的联系。男性吸烟者颈动脉钙化18例（14.1%），非吸烟者颈动脉钙化8例（4.8%），可见50岁及以上男性吸烟更容易发生颈动脉钙化。然而，在同一年龄组中，女性吸烟者和女性非吸烟者之间没有显著差异。牙医在x线片上很容易发现颈动脉钙化。当在x光片上发现这种情况时，应建议患者戒烟并转介给医生作进一步检查。临床医生应该意识到，这一x线检查结果表明存在颈动脉粥样硬化改变。
Panoramic dental radiographs are commonly used in general dentistry and oral and maxillofacial surgery to examine upper and lower teeth, maxilla, mandible and the surroundings simultaneously. Carotid artery calcification, a specific indicator of atherosclerotic change of the carotid arteries, can be seen on the radiographs. Many studies have suggested that cigarette smoking is a risk factor of atherosclerotic change as well as cerebral infarction. We hypothesized that smoking could increase the prevalence of carotid artery calcification, and compared the radiographs of smokers and non-smokers aged 50 years and over: 146 male smokers, 165 male non-smokers, 42 female smokers and 422 female non-smokers. This is the first study to focus on carotid artery calcification seen on panoramic dental radiographs to show the connection between smoking and atherosclerotic change. In male patients, carotid artery calcification was seen in 18 (14.1 %) of the smokers, and in 8 (4.8%) of the non-smokers, which clearly shows that male patients aged 50 years old or over are more likely to develop carotid artery calcification if they smoke. However, there is no significant difference between female smokers and female non-smokers in the same age group. Dentists are In a good position to find carotid artery calcification on radiographs. When this is found on a radiograph, the patient should be advised to stop smoking and be referred to a physician for further tests. Clinicians should be aware that this radiographic finding indicates the presence of atherosclerotic change of the carotid arteries.
