Ultrastructural changes of a tooth root in young rats fed a low calcium and vitamin D-deficient diet.
The aim of the investigation was to assess the ultrastructural changes of the roots of the teeth in young rats fed a low calcium and vitamin D-deficient diet. The studies were carried out on 20 young Wistar rats. The results of the scanning microscopic observations showed the increased cementolysis and decreased mineralization of cementum and dentin in rats fed a low calcium and vitamin D-deficient diet. The results indicated that the hard tissues of the teeth, besides bony system, are also involved in calcium homeostasis in rat organism.
