Abstract
The extent and duration of experimental vascular occlusion in the periodontium of squirrel monkeys was determined by India ink perfusion. Three, hours after the induction of carbonized microspheres, only vessels of the periodontal ligament contained perfusion material. The palatal gingiva was vascularized before the maxillary buccal gingiva, Gingival vessels adjacent to the epithelial attachment and crevicular epithelium vascularized first.
