放射病是由电离放射(如 X-射线、镭锭、放射原素等)对生物体进行体内或体外照射所引起的疾病。关于在放射病时口腔牙周组织的损伤,以往曾有一些报导,主要来自日本广岛长畸原子弹受害者的观察,看到在出现全身放射病症状的同时,口腔各组织也发生明显变化:如放射性口炎、放射龋、边缘性龈炎、牙齿松动等现象。近年来也曾有人通过动物实验同样观察到以上各种改变,这表明了口腔各组织对放射线具有高度敏感性。因此了解电离放射 Radiation disease is a disease caused by in vivo or in vitro exposure of organisms to ionizing radiation (eg X-rays, radiums, radiotransmitters, etc.). Regarding the damage of oral periodontal tissues during radiation sickness, there have been some reports in the past mainly from the observations of the victims of the long-standing atomic bomb in Hiroshima, Japan. In the meantime, there are obvious changes in the oral tissues as well as the symptoms of systemic radiation. For example, Inflammation, radiation caries, marginal gingivitis, loose teeth and so on. In recent years, people have also observed the above changes through animal experiments, indicating that oral tissues are highly sensitive to radiation. So understand ionizing radiation
