The American Academy of Oral and Maxillofacial Radiology established an ad hoc committee to draft evidence-based recommendations and clinical guidance for the application of patient contact shielding during dentomaxillofacial imaging.
The committee reviewed monographs and reports from radiation protection organizations and studies that reported radiation dose to gonads, breasts, and thyroid gland from dentomaxillofacial imaging.
Considering the absence of radiation-induced heritable effects in humans and the negligible dose to the gonads and fetus from dentomaxillofacial imaging, the committee recommends discontinuing shielding of the gonads, pelvic structures, and fetuses during all dentomaxillofacial radiographic imaging procedures. On the basis of radiation doses from contemporaneous maxillofacial imaging, the committee considered that the risks from thyroid cancer are negligible and recommends that thyroid shielding not be used during intraoral, panoramic, cephalometric, and cone-beam computed tomographic imaging.
This position statement informs and educates the reader on evolving radiation protection practices and provides simple, unequivocal guidance to dental personnel to implement these guidelines. State and local authorities should be contacted to update regulations to reflect these recommendations.
美国口腔颌面放射学会成立了一个特别委员会，负责起草在牙科颌面成像中应用患者接触屏蔽的循证建议和临床指南。
委员会审查了来自辐射防护组织的专论和报告，以及报告了来自牙科颌面成像的性腺、乳房和甲状腺辐射剂量的研究。
考虑到人类中不存在辐射诱导的遗传性影响，以及牙科颌面成像对性腺和胎儿的辐射剂量可忽略不计，委员会建议在所有牙科颌面放射成像程序中停止对性腺、骨盆结构和胎儿的屏蔽。根据同期颌面成像的辐射剂量，委员会认为甲状腺癌的风险可以忽略不计，并建议在口腔内、全景、头颅和锥形束计算机断层扫描成像中不使用甲状腺屏蔽。
本立场声明告知并教育读者有关辐射防护实践的最新进展，并为牙科医务人员提供简单、明确的指导，以实施这些指南。应联系州和地方当局，以更新法规，反映这些建议。
