EFFECT OF RADIOISOTOPES ON TEETH AND THEIR SURROUNDING TISSUE
Effect of radioisotopes on teeth and their surrounding tissue was studied using human teeth and the lower jaws and teeth of dogs and rats. Radioisotopes such as P/sup 3//sup 2/, Ca/sup 4//sup 5/, Sr/sup 8//sup 9/, I/sup 1//sup 3//sup 1/, and Bi/sup 2//sup 1//sup 0/ were deposited in the dent ine tissue via the vascular system. The isotopes P/sup 3//sup 2/, Ca/sup 4//sup 5/, Sr/sup 8//sup 9/ and I/sup 1//sup 3//sup 1/ were not distributed in the enamel, but Bi/sup 2//sup 1//sup 0/ showed specific affinity to it. In spite of no deposition of the isotopes in the dentine tissue before the extraction of teeth, there was much affinity to the dentine tissue in the alveolar bones. There were a large number of metabolic exchanges in the growing bones such as the mandibular process. The deposition of isotopes was seen in a relatively short time in the teeth of young animals. In the healing process of wounds in the teeth, Ca/sup 4// sup 5/ was transmitted from the capillaries into the wound more than in the usual calcifLed aress. After calcification the deposition showed an even distribution. (Absts. Japan. Med., 1: No. 7, 1960.)
