[A comparative radioisotope study of calcium metabolism in bone and teeth of rats (author's transl)].

Investigations with bone-seeking radionuclides (47Ca, 99mTc-PP, 113Sn) in rats of different age demonstrated a true accumulation in teeth as compared to bone. Blood flow was evaluated by 99mTcO4 and 51Cr-Albumin. Differences of accumulation depended on the isotopes used and on the age of the animals.
