[The mechanisms of the action of fluorine on periodontal tissues].
It is stated that fluoride intoxication promotes a sharp intensification of the peroxidation processes in the parodontium tissues. It is caused by a respirator explosion of neutrophils, a decrease in activity of antioxidant system enzymes, thus leading to disturbances of microcirculation and blood coagulation, ischemia development. The last factor can retard the enzymatic oxidation in a cell due to hypoxia, injures lysosomal membranes promoting partial autolysis of parodontium tissues, cell structures, intercellular substance. The interaction of blood with destructive elements of cells and collagen favours the development of trombohemorrhagic reactions in the parodontium tissues. A generalized damage of parodontium arises which intensifies under the effect of any other pathogenetic factors.
