Periodontitis is a chronic inflammatory disease that causes destruction of tooth-supporting tissues. Interlukin-20 (IL-20) is a proinflammatory cytokine of the IL-10 family that is involved in some diseases; rheumatoid arthritis, psoriasis, and atherosclerosis. The purpose of this study was to evaluate the levels of IL-20 in gingival crevicular fluid (GCF) and serum of both chronic periodontitis patients and periodontal healthy subjects. Thirty systemically male subjects were categorized into group 1 (healthy) and group 2 (chronic periodontitis patients). The patients were clinically evaluated by; plaque index (PI), bleeding index (BI), probing pocket depth (PD) and clinical attachment loss (CAL). GCF and serum samples were obtained from all individuals to measure IL-20 levels by using of enzyme-linked immunosorbent assay (ELISA) technique. The levels of IL-20 in GCF were significantly higher in chronic periodontitis patients compared to healthy subjects (P ≤ 0.05). In addition, there was a positive correlation between GCF-IL-20 levels and PD (r = 0.800, P= 0.010). While, the serum levels of IL-20 in chronic periodontitis patients were not significant in comparison to healthy subjects (P ≥ 0.05). For Conclusion, significant increased levels of GCF-IL-20 in chronic periodontitis patients showed that IL-20 may have a role in pathogenesis of chronic periodontitis. Moreover, additional studies are required to clarify its role in periodontal diseases.
