Gingival crevicular fluid and its immune mediators in the proteomic era

The discovery of biomarkers for periodontal disease requires an in‐depth understanding of the molecular basis of the initiation and progression of the disease. The gingival crevicular fluid is a biological medium suitable for identifying and measuring such biomarkers because it can be easily and noninvasively sampled from the immediate vicinity of the affected tissues. An ever‐expanding pool of gingival crevicular fluid proteins associated with...
