Variation of the Cytokine Profiles in Gingival Crevicular Fluid Between Different Groups of Periodontally Healthy Teeth

Abstract

Abstract Profiling of biomarkers of physiological process represents an integrative part in optimisation of diagnostic markers in order to adjust the diagnostic ranges to the potential effects of the local factors such occlusal forces in case of periodontal tissues. The objective of this study was estimation of IL-1β, IL-2, IL-4, IL-5, IL-6, IL-9, IL-10, IL-12, IL-13, IL-17, IL-22, TNFα and IFNγ concentrations in gingival crevicular fluid samples (GCF) between different groups of teeth. Two hundred fifty-nine systemically healthy non-smokers having at least one vital tooth without restorations, with healthy periodontal tissues, were clinically examined and the GCF sample was retrieved. The cytokine levels were estimated using flow cytometry and compared between central incisors (CI), lateral incisors, canines, first premolars, second premolars, first molars and second molars. Cytokine profiles varied between different groups of teeth with tendency of increase in proinflammatory cytokines from anterior teeth toward molars. Molars might be considered teeth with natural predisposition for faster bone resorption while the adjustment of diagnostic range of periodontal biomarkers for anterior or posterior teeth should be considered within diagnostic context.
