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.
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.
Six individuals (4.5% of the final study population) had radiopacities which were confirmed by radiographs of the cervical spine to be calcified atheromas. The medical histories revealed risk factors associated with stroke.
Panoramic radiographs obtained during the course of routine dental treatment may demonstrate calcified carotid atheromas in patients at risk of stroke.
确定常规全景牙科X线摄影能否识别颈总动脉分叉处的钙化动脉粥样硬化病变（中风的主要原因）。
纳入牙科诊所连续500例65岁及以上因综合治疗前来就诊且能获得技术上满意的全景X线片的门诊患者。对X线片进行评估，观察第三颈椎下缘水平颈部软组织内是否存在不透X线区。对有此类钙化的个体拍摄颈椎正侧位X线片。从疑似病变患者处获取病史，以确定是否存在已知与中风相关的危险因素。
6例个体（占最终研究人群的4.5%）有不透X线区，经颈椎X线片证实为钙化动脉粥样硬化斑块。病史显示存在与中风相关的危险因素。
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患者的颈动脉钙化粥样硬化斑块。
