[An experimental study of the mechanisms of damage of the periodontal tissues in thyrotoxicosis].

Morphologic studies of the periodontal tissue in rats have revealed that destruction of the maxillodental system in excess of thyroid hormones is explained by disordered mineral metabolism, resorbed osseous tissue of the alveolar process, energy shifts, and developed inflammatory process. Introduction of physiologically-based amounts of calcium, iodine, and fluorine in the animals' ration at the early stages of their development reduced the degree of the alveolar process osseous tissue resorption.
