title: Ultrastructural changes on the root surface in "pressure zone" after experimental movement of teeth in young rats fed a low calcium and vitamin D-deficient diet.
abstract: Dietary calcium and vitamin D-deficiency, as a potential biological factor in etiopathogenesis of root resorption occurring during orthodontic tooth movement, still remains controversial. The aim of the present investigation was to assess the ultrastructural changes on the surface of the root in "pressure zone" after orthodontic tooth movement in rats fed a low calcium and vitamin D-deficient diet. The studies were carried out on 20 young Wistar rats. The results from the scanning electron microscopic showed the increased root resorption in "pressure zone" after orthodontic tooth movement in rats fed a low calcium and vitamin D-deficient diet.
