在生理和病理条件下，龈沟液的pH值可能对龈沟的结构和功能起重要作用。用微量分析新技术测定了人龈沟液的pH值。用毛细管在32个部位（19例患者）收集液体。将对H+离子具有高度选择性的双管中性载体微电极的尖端直接引入含有样品或参比溶液的毛细管中。在每个采样点，[牙龈指数]和龈沟液量被记录并与pH值相关。随着炎症的增加，pH值从6.90升高到8.66。这些值是在20 ℃下测量的。在没有CO2的情况下。这种增加是由于细菌植物群还是由于裂缝区域的任何代谢活动，目前尚不清楚。
In physiological and pathological conditions, the pH of the crevicular fluid may play a significant role on the structure and function of the gingival crevice. The pH of human crevicular fluid was determined by a new microanalytical technique. The fluid was collected in 32 sites (19 patients) with capillary tubes. The tip of a double barreled, neutral carrier based microelectrode, highly selective for H+ ions was introduced directly into the capillary tubes containing either the samples or the reference solutions. In each sampling site, the [gingival index] and the crevicular fluid volume were recorded and correlated with the pH. As the inflammation increased, pH elevated from 6.90 to as much as 8.66. These values were measured at 20.degree. C in the absence of CO2. Whether this increase is due to the bacterial flora or to any metabolic activity in the crevice area is not clear at the moment.
