Experiments on animals (four-week-old dogs) were conducted in an investigation made to study the possibility of dose-dependent tooth-germ damage produced by ionizing radiation. The individual doses were 50 r and 200 r, respectively, and they were administered once to three times at weekly intervals. Hyperemia and edemata could be observed on tooth-germ pulps from 150 r onward. Both of these conditions became more acute as the radiation dose increased (from 150 r to 600 r). Possible damage to both the dentin and enamel is pointed out.
为研究电离辐射产生剂量依赖性牙胚损伤的可能性，对动物（四周龄犬）进行了实验。个体剂量分别为50伦琴和200伦琴，每周间隔给予一次至三次。从150伦琴起，可观察到牙胚牙髓充血和水肿。随着辐射剂量增加（从150伦琴至600伦琴），这两种情况都变得更加严重。指出牙本质和釉质可能受到损伤。
