Ultrastructural study of the mitochondria in the submandibular gland, the pancreas and the liver of young rats, exposed to NaF in drinking water.

The aim of the experiment was to determine the effect of fluoride on ultrastructural changes in the submandibular gland, the pancreas and the liver. The experimental rats received fluoride in aqueous solutions of sodium fluoride at concentrations of 10.6 NaF/dm3 and 32.0 NaF/dm3. In the ultrastructural examination, mitochondria were most damaged.
