About

The purpose of this study was to investigate and compare GCF interleukin-1β (IL-1β), interleukin-10 (IL-10), interleukin-36γ (IL-36γ) levels in patients with healthy (H), gingivitis (G) and chronic periodontitis (CP) status.

Full description

Gingival crevicular fluid (GCF) is formed when fluid exudes from the vessels of the microcirculation into the inflamed periodontal tissue and into the sulcus or pocket. As the fluid traverses the inflamed tissue, it is thought to pick up enzymes and other molecules that participate in the destructive process, as well as products of cell and tissue degradation. Efforts to develop diagnostic tests based on host factors have been focused almost entirely on analysis of GCF.

The purpose of this study was to investigate and compare GCF interleukin-1β (IL-1β), interleukin-10 (IL-10), interleukin-36γ (IL-36γ) levels in patients with healthy (H), gingivitis (G) and chronic periodontitis (CP) status.

Systemically healthy and non-smokers 80 participants (30 males and 50 females) who were selected from among admitting to Dentistry Faculty of Selcuk University were included in this study. Clinical periodontal parameters were recorded and GCF samples were obtained. Samples were stored in -80 ˚C until analysis with Enzyme-Linked ImmunoSorbent Assay (ELISA).
