The oxygen tension of dog gingiva was measured before and after administration of dinitrophenol in amounts sufficient to raise whole body metabolism as much as fourfold. Gingival oxygen tension did not decrease significantly from the normal (av. 56 mm/Hg) after induction of the metabolic rate increase. The vascular supply of the gingiva is viewed as being sufficiently adaptable to meet the increased demand for oxygenated blood caused by increased metabolism.
