Evaluation of Saliva IL-6 Levels and Periodontitis

Association Between Salivary IL-6 and Extent of Periodontitis

The aim of this study was to analyze the association between salivary IL-6 levels in patients with periodontitis. Furthermore, the objective was to determine if the periodontitis influenced salivary IL-6 levels

Forty-nine patients with periodontitis and 47 healthy subjects (HS) were enrolled in the present study. Enrolled patients were examined and characterized for clinical and blood samples analysis, and salivary IL-6 levels. The Spearman Correlation Test and Jonckheere-Terpstra Test were applied in order to assess the interdependence between salivary IL-6 levels and clinical periodontal parameters.
