[New concept on the mechanism of hypoxia in case of periodontitis].

In examined groups of healthy people as well as in persons suffering from a periodontitis of a different severity-degree with concomitant affections and without them the PO2 in the blood is defined by the concentration of K+ and Cl- in erythrocytes and in blood as well as by the relation between the Cl(-)-concentrations on both the sides of the erythrocyte membrane. The disorders in the concentrations of these electrolytes in patients suffering from a periodontitis use to lead to a defect of the ability of haemoglobin to bind the oxygen as well as to transport it through the erythrocyte membrane, a fact entailing a decrease of PO2 in the blood in this group of sick persons. A decrease of PO2 in the blood for its part may cause in persons suffering from a periodontitis a hypoxia in the periodontal tissue and in other tachytrophic organs.
