[Measurement of the oxyten partial pressure in the gingiva].

The partial pressure of oxygen (pO2) in the inflamed gingiva was measured in 24 patients before and after the application of Gingivox. The Gingivox treatment led to a significant increase in pO2 from 72.2 mm Hg to 94.6 mmHg. The arterial pO2 values of all patients, measured on the hyperaemic ear-lobe, lay within the range of normal values. The measurements were performed by means of the micro-Astrup equipment of the firm of Radiometer, Copenhagen.
