In the aim to support treatments and diagnostics in Dentistry the most common radiographies are the periapical radiography and the dental panoramic. In the dental panoramic the X-ray beam is addressed into a large zone of the face obtaining the image of the upper and lower jaw. In this procedure part of the X-rays are scattered reaching some other parts of the patient body. In this work the absorbed dose in the eye lens, thyroid, salivary glands, mammary glands, and gonads, was measured in patients undergoing a dental orthopantomography. Measurements were carried out with thermolmuminiscent dosimeters. With the absorbed doses the Effective dose were calculated. The highest dose was obtained in the salivary glands (30.4 μSv) and the lowest dose was obtained in thyroid (3.8 μSv).
为了辅助牙科的治疗和诊断，最常见的放射检查是根尖周放射摄影和牙科全景摄影。在牙科全景摄影中，X射线束照射面部的一大片区域，以获取上下颌的图像。在这个过程中，部分X射线会散射到患者身体的其他部位。在这项研究中，对接受牙科曲面断层摄影的患者的晶状体、甲状腺、唾液腺、乳腺和性腺的吸收剂量进行了测量。测量使用热释光剂量计进行。根据吸收剂量计算出有效剂量。唾液腺获得的剂量最高（30.4μSv），甲状腺获得的剂量最低（3.8μSv）。
