Aim
The aim of the present study was to quantify IL6, IL-8, IL-12, and IL-17 levels in the saliva and GCF for patients with generalized periodontitis and compare it with healthy subjects. Furthermore, identifying the most reliable biofluids (saliva and GCF) that can be utilized for biomarkers detection in periodontitis patients.
Background
Biomarkers present in the oral fluid (saliva and GCF) have been studied thoroughly in order to be used as adjuncts to the diagnosis of periodontal disease. In periodontal diseases, inflammatory mediators, including IL6, IL-8, IL-12, and IL-17, may promote the degeneration of periodontal tissues.
Conclusions
The mean levels of IL6, IL-8, IL-12, and IL-17 either in saliva or GCF were higher in periodontitis patients than in healthy subjects. These results suggest that the levels of IL6, IL-8, IL-12, and IL-17 in GCF or saliva may be relevant in the pathophysiology of periodontitis, and the measurement of these cytokines may be beneficial in the identification of patients with periodontitis. Furthermore, some biomarkers for periodontal disease are detected better in saliva, while others are best detected in GCF.
