In a first pilot field study 64 gingival crevicular fluid (GCF) samples were collected from patients of dental practitioners. The dentists (one orthodontist one periodontist, and one general practitioner) were asked to monitor the respective clinical status of the sites of sampling and to collect, if possible, sulcus fluid samples from healthy as well as affected sites from the same patient. The concentration of activated matrix metalloproteinase-8 (aMMP-8) in the GCF was recorded using a set of monoclonal antibodies and a novel DentoAnalyzer. From all three dental offices the distribution of the aMMP-8 values in GCF showed a congruent pattern, where healthy and periodontitis-affected inflamed sites were clearly disparate.
