The information value of crevicular fluid immunoregulatory mediator quantitative assessment in predicting the nature of the inflammatory periodontal disease course

Abstract

Relevance. Clinical and radiological assessment mainly forms the diagnosis of periodontal diseases. The diagnosis now requires speed, sensitivity and specificity since determining the patient's disease stage is fundamental to effective treatment. Crevicular fluid biomarkers can help monitor the current state of the disease, the effectiveness of treatment, and possibly predict the pathological process progression. The combination of various biomarkers will allow maximum objectivity in periodontal tissue condition assessment.Materials and methods. The study examined 72 patients with inflammatory periodontal diseases and 25 periodontally healthy subjects. We performed a conventional clinical-instrumental examination and studied pro- and anti-inflammatory interleukins (IL-1β, IL-6, IL-17, TNF-α, VEGF, IL-8, MCP-1, IL-1RA) in the crevicular fluid. The obtained materials were processed using ROC analysis.Results. Inflammatory periodontal diseases demonstrate an increase in pro-inflammatory cytokines / chemokines (IL-1β, TNF-α, IL-6, IL-17, IL-8, MCP-1) and vascular endothelial growth factor (VEGF) in the crevicular fluid, a decrease in the anti-inflammatory cytokine, IL-1RA. The levels of pro- and anti-inflammatory cytokines, cytokines/ chemokines, VEGF are associated with the periodontal destruction severity caused by inflammation. The accumulation of VEGF, IL-6, and IL-1β in the crevicular fluid predicts the clinical course of gingivitis, VEGF, TNF-α, IL-6, IL-1β – mild and moderate periodontitis.Conclusion. The present study allows us to confirm the diagnostic value of methods for obtaining and quantifying a group of immunoregulatory cytokines in the crevicular fluid as predictors and parameters of the disease progression and the development of osteodestructive changes in the periodontium.
