Abstract
The existence and the extent of periodontal disease can be diagnosed by measuring plasminogen activator inhibitor 2 (PAI-2) and/or tissue plasminogen activator (t-PA) levels in gingival crevicular fluid (GCF). Levels of PAI-2 and t-PA in GCF rise sharply in the context of periodontal disease, and they also correlate with the severity of disease at different sites in the same patient.
