Objectives: Pentraxin-3 (PTX3) and interleukin-6 (IL-6) are two of the most important inflammatory cytokines produced by cells in periodontal tissues. The present study aims to evaluate the levels of PTX3 and IL-6 in serum and gingival crevicular fluid (GCF) in patients with generalized periodontitis stages II and III, grades A and B, and periodontal health individuals before and after scaling and root planing (SRP).
Materials and Methods: In this study, 22 patients with periodontitis (12 males and 10 females) and 22 periodontal health controls (11 males and 11 females) were selected. All patients underwent full-mouth SRP. Serum and GCF samples were collected before and one month after SRP. PTX3 and IL-6 levels in serum and GCF samples were evaluated by enzyme-linked immunosorbent assay. Data analysis was performed using Mann-Whitney U and Wilcoxon tests (P<0.05).
Results: Serum levels of PTX3 were significantly higher in the periodontitis group than the controls (P<0.05). GCF PTX3 levels and serum and GCF IL-6 levels were not significantly different between the groups. Furthermore, this study did not show any significant changes in the levels of these cytokines before and after SRP.
Conclusion: Among the studied cytokines and media, only serum PTX3 levels showed a significant difference between periodontitis patients and healthy controls and could serve as a diagnostic marker of periodontal inflammation. SRP did not affect the levels of these cytokines, suggesting that other inflammatory factors may be involved in disease process. However, additional longitudinal prospective studies are needed to confirm these results.
