Discovery-phase study analyzes proteins in gingival crevicular fluid, revealing inflammation markers in furcation defects.
This study analyzed the gingival crevicular fluid (GCF) proteome of 35 patients with Grade II furcation defects using the Olink Reveal platform. Comparison with non-periodontitis sites identified 227 differentially expressed proteins. A machine-learning pipeline prioritized a 34-protein signature (including GLIPR1, MME, and IRAG2) that accurately differentiated furcation defects from health (AUC = 0.887), reflecting a distinct profile of severe inflammation and neutrophil activation.
