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.
