龈沟液(gingival crevicular fluid,GCF)中前列腺素E_2(prostaglandin E_2,PGE_2)的水平可以作为临床、亚临床疾病的一项诊断指标。本实验目的在于检测和比较牙周炎抵抗患者与牙周炎易感患者GCF中PGE_2的水平。 材料和方法 将患者分为两组,第一组为牙周炎抵抗(periodontal disease-resistant,PDR)组,共20名,基本条件为:35岁以上,具有慢性龈炎的临床表现,检测位点牙龈指数大于2,X线示釉牙骨质界到牙槽嵴的距离小于2mm;第二组为牙周炎易感组
The level of prostaglandin E_2 (PGE_2) in gingival crevicular fluid (GCF) can be used as a diagnostic indicator of clinical and subclinical diseases. The purpose of this experiment is to detect and compare the level of PGE_2 in GCF of patients with periodontal resistance and periodontitis-susceptible patients. Materials and Methods The patients were divided into two groups. The first group consisted of 20 patients with periodontal disease-resistant (PDR) group. The basic conditions were: over 35 years old, with clinical manifestations of chronic gingivitis, Gingival index greater than 2, X-ray enamel cementum to the alveolar ridge distance less than 2mm; the second group of periodontitis susceptible group
