Analysis of YKL‐40 Acute‐Phase Protein and Interleukin‐6 Levels in Periodontal Disease

Abstract

YKL-40 levels in GCF as well as serum YKL-40 and IL-6 levels increased from gingivitis to periodontitis. Within the limits of the present study, the YKL-40 molecule might be a potential novel inflammatory marker of periodontal disease.
