Abstract
Disclosed are methods for determining the presence of periodontal disease in mammals. The methods include the steps of (1) sampling gingival crevicular fluid, (2) assaying the crevicular fluid sample by colorimetric or other means to determine levels of alanine aminotransferase present, and (3) correlating the levels of L-alanine aminotransferase present in the crevicular fluid sample with a standard which is indicative of the presence of periodontal disease.
