Time course of functional hyperemia in the periodontium was studied by quantitative rheography in 99 subjects, 55 of these presenting with periodontal diseases and 43 with clinically normal periodontium. Chewing of 5 cm3 of raw carrots for 30 sec on the working side was used as a functional exercise. In normal or reduced tone of regional vessels an oscillatory process of functional hyperemia with a latent period was developing, presumably at the expense of rise of osmotic pressure of tissue fluid. In initial vasoconstriction functional hyperemia develops without latent period and oscillatory process. A similar picture is observed in periodontal diseases, but the bloodstream volume is far less.
通过定量血流描记法研究了99名受试者牙周组织功能性充血的时程，其中55名患有牙周疾病，43名牙周组织临床正常。以在患侧咀嚼5立方厘米生胡萝卜30秒作为功能锻炼。在局部血管张力正常或降低的情况下，功能性充血的振荡过程伴有潜伏期，推测这是以组织液渗透压升高为代价的。在初始血管收缩时，功能性充血的发展没有潜伏期和振荡过程。在牙周疾病中观察到类似情况，但血容量要少得多。
