Hard teeth tissues in rats with experimental rickets. Examinations in electron scanning microscope and microanalyser.
The experiments were carried out on Wistar rats with rickets experimentally induced. The following examinations were made: radiological examinations of the jaws, a teeth analysis in the microanalyser for the distribution of fundamental elements, and ultrastructure observations in the scanning electron microscope. The jaws of the experimental rats were smaller in the radiological picture. The disturbed arrangement of the enamel prisms was found in the enamel substructure of the experimental rats. Phosphorus values in the enamel and dentine were lower in the experimental animals. Calcium to phosphorus ratio was higher in the rachitic rats. Disturbances of calcium-phosphorus balance were observed.
