Abstract

Disclosed is an in vitro method for assessing whether a human patient has periodontitis. The method is based on the insight to determine biomarker proteins. Accordingly, in a sample of saliva a patient suffering from periodontitis, the concentrations are measured of the Free Light Chain κ protein and/or the Free Light Chain λ. Based on the concentration(s) as measured, a value is determined reflecting the concentration or joint concentrations for said protein or proteins. This value is compared with a threshold value reflecting in the same manner the concentration or joint concentrations associated with periodontitis. The comparison allows assessing whether the testing value is indicative of the presence of periodontitis in said patient. Thereby, typically, a testing value reflecting a concentration or joint concentration below the concentration or joint concentration reflected by the threshold value is indicative for absence of periodontitis in said patient, and a testing value reflecting a concentration or joint concentration at or above the concentration or joint concentration reflected by the threshold value, is indicative for periodontitis in said patient.
