对龈沟液(GCF)的研究已近一百年之久,但GCF的产生及其意义仍然是争论的问题。有人认为GCF的存在是一种正常现象,它的唯一意义是龈下结石盐的来源。而另有人认为临床上健康的龈组织,是无龈沟液的,一定量的龈沟渗出液可作为不同程度牙龈炎症的临床指征。GCF的量与临床牙上龈炎症反应有关。还有人研究了GCF与牙龈炎的组织学分级之间的关系。本研究的目的是进一步确定测定龈沟液的量是否可作为牙龈炎症轻重程度的一个指征。并进而确定牙龈指数(GI)、GCF流量、龈沟pH值和牙龈炎的组织学分级之间的关系。
Gingival crevicular fluid (GCF) research has been nearly a hundred years, but the production of GCF and its significance remains a controversial issue. Some people think that the existence of GCF is a normal phenomenon, its only significance is the source of subgingival stones salt. Others think clinically healthy gingival tissue is gingival crevicular fluid, a certain amount of sulcus gingival crevicular fluid can be used as a different degree of clinical indications of gingival inflammation. The amount of GCF is related to the clinical gingivitis response. Others have studied the relationship between GCF and the histological grade of gingivitis. The purpose of this study was to further determine whether determining the amount of GCF as an indication of the severity of gingival inflammation. And then to determine the relationship between gingival index (GI), GCF flux, gingival sulcus pH, and histological grade of gingivitis.
