The author observed the effect of x-ray irradiation on the development of the
mandible in the fetuses and growing albino rats. The fetuses were irradiated on the 7¨ö
th day of gestation, 100, 200, 300, and 400 rads of x-ray respectively. The experimental
animals were sacrificed on the 18¨öth day of gestation, and first week, second week and
third week after parturition.
The results were as follows ;
1. The mandible of the 18¨öth day fetuses showed irregular bone trabeoulae,
osteoclasts and osteocyte degeneration on the 300 and 400 rads x-ray irradiated fetuses.
2. In the mandible of the first week rats, there was marked osteocyte degeneration
and a lot of osteoclast.
3. In the mandible of the 2nd and 3rd week rats bone remodeling was evident. The
3rd week rats also showed alteration of blood vessel wall.
