Objective.确定颈总动脉分叉处钙化的动脉粥样硬化病变（卒中的主要原因）是否可以通过传统的全景牙科X线片识别。所有年龄在65岁或以上的患者，在牙科诊所接受综合治疗的500名连续门诊患者中，有可能获得技术上令人满意的全景X光片。评价X线片在第三颈椎下缘水平处颈部软组织内是否存在射线不透性。对有钙化的患者进行颈椎前后位X线片检查。从可疑病变患者中获取病史，以确定已知与卒中相关的危险因素的存在。6名个体（最终研究人群的4.5%）存在射线不透性，经颈椎X线片证实为钙化颈动脉粥样硬化。病史揭示了脑卒中的危险因素。在常规牙科治疗过程中获得的全景X线片可能显示有中风风险的患者的钙化颈动脉粥样硬化。
Objective. To determine if calcified atherosclerotic lesions in the region of the bifurcation of the common carotid artery (a major cause of stroke) can be identified by conventional panoramic dental radiography.Methods. All those aged 65 years or older, of 500 consecutive out-patients enrolled in the dental clinic for comprehensive treatment and for whom it was possible to obtain a technically satisfactory panoramic radiograph, were included. The radiographs were evaluated for the presence of radiopacities within the soft tissues of the neck at the level of the lower margin of the third cervical vertebra. An antero-posterior cervical spine radiograph was obtained of those individuals with any such calcifications. Medical histories were obtained from patients with suspected lesions in order to determine the presence of risk factors known to be associated with stroke.Results. Six individuals (4.5% of the final study population) had radiopacities which were confirmed by radiographs of the cervical spine to be calcified carotid atheromas. The medical histories revealed risk factors associated with stroke.Conclusion. Panoramic radiographs obtained during the course of routine dental treatment may demonstrate calcified carotid atheromas in patients at risk of stroke.
