Mineralization in teeth and jaws, as judged radiographically, in rats of the COSMOS-782 experiment

摘要

The data on mineralization of the teeth in rats of the COSMOS-782 joint biology satellite experiment is presented. Estimations were made from radiographs by optical densitometry. The bone resorption of spongy bone in the rats in discussed. Special efforts were made to standardize the regions of tooth structure being measured, in the hoe that masses of tissue of low experimental reactivity might not obscure more highly reactive sites.
