Abstract

Purpose: Given the growing use of cone-beam computed tomography (CBCT) scans, this study assessed radiation exposure from these scans in the context of national guidelines and recommended dose limits.

Materials and methods: The current literature was reviewed to quantify the benefit of opportunistic diagnosis of carotid artery calcification relative to the potential risk of radiation-induced cancer.

Results: The average radiation from CBCT at its largest field of view and highest resolution possible amounts to a reasonable but still low ionizing radiation exposure. This exposure is comparable to 22 days of background radiation and is notably lower than the radiation exposure from medical CT scans. According to the risk assessment analysis, the risk of stroke events involving internal and external carotid artery calcification (CAC) was 202 and 67 per 100,000 individuals, respectively. In contrast, the estimated risk of radiation-induced cancer associated with CBCT was notably lower, at 0.6 per 100,000.

Conclusion: The present study advocates for a comprehensive assessment of CBCT scans encompassing the areas of the internal and external carotid arteries by a knowledgeable professional, given the potential advantages of early detection of vascular abnormalities. Dental professionals who take scans involving these areas need to be mindful of reporting these findings and refer patients to their primary care physician for further investigation.

利用三维牙科成像对血管钙化进行机会性研究。
目的:鉴于锥形束计算机断层扫描(CBCT)的使用日益增多,本研究根据国家指南和建议的剂量限制评估了这些扫描的辐射暴露:研究人员查阅了现有文献,以量化颈动脉钙化机会性诊断的益处与辐射诱发癌症的潜在风险:CBCT在最大视野和最高分辨率下产生的平均辐射相当于合理但仍然较低的电离辐射暴露量。这种辐射量相当于 22 天的背景辐射量,明显低于医疗 CT 扫描的辐射量。根据风险评估分析,涉及颈内动脉钙化(CAC)和颈外动脉钙化(CAC)的中风风险分别为每 10 万人 202 例和 67 例。相比之下,与 CBCT 相关的辐射诱发癌症的估计风险明显较低,为每 10 万人 0.6 例:鉴于早期发现血管异常的潜在优势,本研究提倡由知识渊博的专业人员对包括颈内动脉和颈外动脉区域的 CBCT 扫描进行全面评估。牙科专业人员在扫描这些区域时需要注意报告这些发现,并将患者转诊给主治医生做进一步检查。
