GINGIVITIS DIAGNOSTIC METHODS, USES AND KITS

Disclosed is an in vitro method for assessing whether a human patient has gingivitis. The method is based on the insight to determine biomarker proteins. Accordingly, in a sample of saliva a patient suffering from gingivitis, the concentrations are measured of the certain protein combinations. One such combination is Alpha-1-acid glycoprotein (A1AGP) and S100 calcium-binding protein A8 (S100A8), and at least one of Hemoglobin subunit beta (Hb-beta), Keratin 4 (K-4) and Pyruvate Kinase (PK). Another combination is Alpha-1-acid glycoprotein (A1AGP), Hemoglobin subunit beta (Hb-beta) and Keratin 4 (K-4). Based on the concentrations as measured, a value is determined reflecting the joint concentrations for said proteins. This value is compared with a threshold value reflecting in the same manner the joint concentrations associated with gingivitis. The comparison allows assessing whether the testing value is indicative of the presence of gingivitis in said patient. Thereby, typically, a testing value reflecting a joint concentration below the joint concentration reflected by the threshold value is indicative for absence of gingivitis in said patient, and a testing value reflecting a joint concentration at or above the joint concentration reflected by the threshold value, is indicative for gingivitis in said patient.
