GCF and Saliva Levels of IL-36α in Periodontal Disease

Overview

Interleukin-36 (IL-36), recently identified and members of the IL-1 family, have been reported to be important regulators of host defense against pathogens in the oral mucosa. The aim of this study was to investigate the levels of IL-36 alpha (α) in saliva and gingival crevicular fluid (GCF) of patients with periodontitis, gingivitis and periodontally healthy individuals and to compare these levels with clinical parameters.

Interleukin-36 (IL-36), recently identified and members of the IL-1 family, have been reported to be important regulators of host defense against pathogens in the oral mucosa. The aim of this study was to investigate the levels of IL-36 alpha (α) in saliva and gingival crevicular fluid (GCF) of patients with periodontitis, gingivitis and periodontally healthy individuals and to compare these levels with clinical parameters. Materials and Methods: A total of 80 systemically healthy, non-smokers aged between 25 and 55 including 20 periodontally healthy individuals, 20 individuals with gingivitis, 20 individuals with Stage III Grade B periodontitis, and 20 individuals with Stage III Grade C periodontitis were involved in our study. Clinical parameters, including plaque index (PI), gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL), and bleeding on probing (BOP), were recorded. GCF and unstimulated saliva samples were collected from all participants. IL-36α levels were quantified using enzyme-linked immunosorbent assay (ELISA).
