Abstract
This invention provides a method of diagnosing periodontal disease in a subject by detecting elevated concentrations of .beta.-glucuronidase in saliva from the subject. The concentration of .beta.-glucuronidase in the subject's saliva may be determined by adding to a sample of the saliva a substrate for .beta.-glucuronidase and measuring the amount of a product produced by the reaction of .beta.-glucuronidase on the substrate. Also, the concentration of .beta.-glucuronidase in the subject's saliva may be determined by adding to a sample of saliva a labeled antibody specific for .beta.-glucuronidase and measuring the amount of labeled antibody which complexes with .beta.-glucuronidase present in the saliva.
