  • Publication number: 20230417769
    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.

  • Publication number: 20230393149
    Abstract: Disclosed is an in vitro method for assessing the presence of gingivitis in a human subject. The method is based on the insight to determine a selection of three biomarker proteins. Accordingly, in a saliva sample of the subject the concentrations are measured of the proteins Hepatocyte growth factor (HGF) and Interleukin-1? (IL-1?), and at least one of C reactive protein (CRP) and Haemoglobin. 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 the absence of gingivitis or periodontitis. The comparison allows to assessing whether the testing value is indicative of the presence of gingivitis in said subject. Thereby, typically, a testing value reflecting a joint concentration above the joint concentration reflected by the threshold, is indicative of the presence of gingivitis.

  • Publication number: 20210382069
    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 bio marker proteins. Accordingly, in a sample of saliva a patient suffering from periodontitis, the concentrations are measured of the proteins Pyruvate Kinase (PK) and at least two of Haemoglobin-beta (Hb-beta), Haemoglobin-delta (Hb-delta), S100 calcium-binding protein A8 (S100A8) and S100 calcium-binding protein A9 (S100A9). 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.

  • Patent number: 11105792
    Abstract: A system for detecting halitosis is disclosed that comprises a gas sensor (116) for generating a sensor signal signalling the detection of compounds indicative of halitosis exhaled through an oral cavity; an image sensor (114) for capturing an image (500, 510) of a dental condition and/or tongue condition in said oral cavity; and a processor (110) communicatively coupled to the gas sensor and the image sensor and adapted to process the sensor signal and the image in order to determine if in case of the sensor signal signalling the presence of a compound indicative of halitosis, said halitosis originates from said oral cavity by determining the dental condition and/or tongue condition in said image. A method for detecting halitosis and a computer program product implementing the method are also disclosed.

  • Publication number: 20210181209
    Abstract: Disclosed is a system, a kit, a use and an in vitro method for assessing whether a human patient suffering from periodontitis has mild periodontitis or advanced periodontitis. The system and method are based on the insight to apply a clustering technique to a reference set of patient data, and then further discriminating the sets of bio markers to be applied. The clusters are determined on the basis of the biomarkers Hepatocyte Growth Factor (HGF), Matrix metalloproteinase 8 (MMP8), and Matrix metalloproteinase 9 (MMP9). The actual classification of the patient is done on the basis of the measurement of the concentrations of either of two sets of biomarkers. For one cluster these are Interleukin-1? (IL1?), Interleukin-6 (IL6), and Collagen Telopeptide. For the other cluster, these are HGF and metallopeptidase inhibitor 1 (TIMP1).

  • Publication number: 20210164995
    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.

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.
