The effect of gum chewing (5 min after meals 3 times a day) on periodontal blood supply was studied in a group of 52 volunteers with different clinical status of the periodontium. Tonic strain in the local vessels changed (fluctuated) little (by 2-7%). Tonic strain was shifted on the inert side and in patients with periodontal diseases. Blood consumption increased by 33%. Regular gum chewing for 10 min resulted in compensatory vasoconstriction and hyperemia of the periodontium starting from the second week, irrespective of the initial clinical status of the periodontium.
在一组52名牙周组织临床状况各异的志愿者中，研究了饭后咀嚼口香糖（每天3次，饭后5分钟）对牙周血液供应的影响。局部血管的张力应变变化（波动）很小（2%-7%）。在牙周疾病患者中，张力应变向惰性侧偏移。血流量增加了33%。无论牙周组织的初始临床状况如何，从第二周开始，每天规律咀嚼口香糖10分钟会导致牙周组织出现代偿性血管收缩和充血。
