Concentrations of Interleukin-1ß in Gingival Crevicular Fluid and Saliva - a Potential Diagnostic Biomarker of Periodontal Diseases.

INTRODUCTION: Bacterial challenge in periodontal diseases activates both local and systemic immune responses of a macroorganism by increasing multiple proinflammatory factors that can be discovered in gingival crevicular fluid (GCF) and in saliva. We tested the hypothesis that IL-1β concentration in GCF and saliva correlates with periodontal health and diseases. Materials and methods: The study included 62 people (mean age 36±14 yrs), divided into three groups - patients with periodontitis (24 people), patients with gingivitis (19 people) and periodontally healthy people (19 people). Saliva and GCF samples were taken from all participants and the levels of IL-1β in all samples were determined by ELISA.

RESULTS: IL-1β concentrations in GCF of healthy individuals were significantly lower than the IL-1β concentration in GCF of patients with gingivitis (p=0.009) and with periodontitis (p.
