It has been shown that the ionic concentration of gingival crevicular fluid (GCF) rises with increases in the inflammation of the surrounding tissue. Because measurement of this increase might be useful for clinical assessment of periodontal status and because the sampling of this fluid is difficult in the typical clinical environment, attempts were made to measure the conductivity of GCF in vivo using a fabricated conductivity probe. Preliminary results suggest that statistically significant correlations may exist between certain clinical indices and GCF conductivity. A correlation could be shown when comparing the Gingival Index and the measured conductivity of GCF, but the correlation may be too low to be of biologic relevance, possibly due to the use of pooled samples. The use of an ion-specific probe and the study of site-specific periodontal lesions are suggested to develop more definitive data than this pilot study provided.
研究表明，龈沟液（GCF）的离子浓度会随着周围组织炎症的加剧而升高。由于测量这种升高可能有助于牙周状况的临床评估，并且在典型的临床环境中采集这种液体很困难，因此尝试使用制造的电导探针在体内测量GCF的电导率。初步结果表明，某些临床指标与GCF电导率之间可能存在统计学上的显著相关性。在比较牙龈指数和测量的GCF电导率时可以显示出相关性，但这种相关性可能太低，以至于没有生物学相关性，这可能是由于使用了混合样本。建议使用离子特异性探针并研究特定部位的牙周病变，以获得比这项初步研究所提供的更确切的数据。
