A systematic review of biomarkers of gingival crevicular fluid: Their predictive role in diagnosis of periodontal disease status

Abstract

The objective of the study was to conduct a systematic review of the literature so as to evaluate and summarize the diagnostic and prognostic potential of GCF. Included studies were systematically analyzed based on PRISMA (Preferred Reporting Items For Systematic Reviews and Meta Analyses) and studies were identified based on the-PICO (Glossary of evidence based terms 2007): 1) Patients with chronic periodontitis. 2) Intervention- NSPT (Non-SurgicalPeriodontal therapy); NSPT + Chemotherapeutics. 3) Comparison between treated v/s non treated sites. 4) Outcomes measured: Analysis of variation in constituents of GCF.Electronic database search of Pubmed, Medline, Google Scholar and Scopus was performed using (MeSH) terms- Gingival Crevicular fluid and Cytokines, MMP’s, NE, PGE-2, A2M, B2M, ALP, AST, Osteocalcin and Calprotectin. Articles published between year 2000-2016 were reviewed and were included based on inclusion and exclusion criteria.Based on this systematic review of literature, it can be concluded that analysis of constituents of GCF can be used as an effective and efficient diagnostic tool of periodontal diseases. These biomarkers in turn with their prognostic significance could act as a valuable tool in the combat of periodontal disease.
