[The problem of damage to the tooth germ by ionizing radiation].
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.
