Abstract: Disclosed is an in vitro method for assessing whether a human subject has periodontitis. The method comprises detecting, in a sample of saliva from said subject, the concentrations of the proteins Hepatocyte Growth Factor (HGF) and Matrix Metalloproteinase 8 (MMP-8). Based on the concentrations determined, and adding age, and possibly other demographic markers such as sex and/or BMI, a testing value reflecting the joint concentrations is determined for said proteins, in combination with one or more demographic markers. The testing value is compared with a threshold value. The threshold reflects in the same manner the joint concentrations and the age, and possibly other demographic markers, as associated with periodontitis and may be seen as an upper limit of testing values as seen in a population of subjects without periodontitis. Thereby a testing value at or above the threshold value is indicative for periodontitis in said subject.

Abstract: 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.

Abstract: Disclosed is an in vitro method for assessing whether a human patient suffering from periodontitis has mild periodontitis or advanced periodontitis. The method is based on the insight to determine a selection of three biomarker proteins. Accordingly, in a sample of saliva a patient suffering from periodontitis, the concentrations are measured of the proteins Interleukin-1β (IL-1β), Matrix metalloproteinase-9 (MMP-9) and at least one of the proteins: Interleukin-6 (IL-6), and Matrix metalloproteinase-3 (MMP-3). 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 advanced periodontitis. The comparison allows assessing whether the testing value is indicative of the presence of advanced periodontitis or of mild periodontitis in said patient. Thereby, typically, a testing value reflecting a joint concentration below the joint concentration reflected by the threshold value is indicative for mild periodontitis 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 advanced periodontitis in said patient.

Abstract: Disclosed is an in vitro method for assessing or predicting the response of a human patient to treatment of periodontal disease. The method is based on the insight to determine biomarker proteins. Accordingly, in a sample of saliva of a patient, the concentrations are measured of certain protein combinations. One such combination is Alpha-1-acid glycoprotein (A1AGP) and at least one of Interleukin-1-beta (I-1β) and 5 Matrix metalloproteinase-8 (MMP-8). Based on the concentrations as measured, at least one value is determined reflecting the joint concentrations for said proteins. This at least one value may indicate the probability that human patient has been or will be successfully treated for the periodontitis. The at least one value can be compared with at least one threshold value reflecting in the same manner the joint concentrations associated with successful treatment of 10 periodontitis. The comparison allows assessing whether the testing value is indicative of the periodontal treatment status in said patient.
