This study evaluated the radiation dose reduction, operator acceptance, and patient acceptance of two types of leaded thyroid shields designed for use during intraoral dental radiography. Exposure levels were measured with thermoluminescent dosimeters on three groups of 20 patients undergoing complete mouth (20-film) surveys. Skin entrance dose to the thyroid was 20 mR per complete mouth survey without a shield in place, 12 mR per complete mouth survey with the experimental shield in place, and 9 mR with the commercial shield. Patients and radiologic technologist were surveyed to determine patient comfort and operator acceptability. Patient and operator acceptability were higher for the experimental shield than for the commercial shield.
本研究评估了两种用于口腔内牙科X线摄影的含铅甲状腺防护盾的辐射剂量降低情况、操作者接受度和患者接受度。使用热释光剂量计对三组20名接受全口（20张胶片）检查的患者进行了照射水平测量。在不使用防护盾的情况下，全口检查时甲状腺的皮肤入口剂量为每次20 mR，使用实验性防护盾时为每次12 mR，使用商用防护盾时为9 mR。对患者和放射技师进行了调查，以确定患者的舒适度和操作者的可接受性。实验性防护盾的患者和操作者接受度高于商用防护盾。
