Specified Species in Gingival Crevicular Fluid Predict Bacterial Diversity

Specified Species in Gingival Crevicular Fluid Predict Bacterial Diversity

BACKGROUND Analysis of gingival crevicular fluid (GCF) samples may give information of unattached (planktonic) subgingival bacteria. Our study represents the first one targeting the identity of bacteria in GCF. METHODOLOGY/PRINCIPAL FINDINGS We determined bacterial species diversity in GCF samples of a group of periodontitis patients and delineated contributing bacterial and host-associated f...

Gingival Crevicular Fluid Biomarkers

Material and Method: Thirty patients were allocated into 3 groups: 10 were treated with scaling and root planing (SRP) only; 10 were treated with SRP and received adjunctive local metronidazole; 10 were treated with SRP and received adjunctive systemic metronidazole. Periodontal clinical parameters including plaque index, sulcus bleeding index, probing depth and relative attachment level were r...

Hydroxyproline titers in gingival crevicular fluid.

IL-34 Expression in Gingival Fibroblasts, Gingival Crevicular Fluid and Gingival Tissue

Hydroxyproline determination in serum and gingival crevicular fluid.

A high-performance hquid chromatographic assay for total hydroxyproline in serum and gingival crevicular fiuid has been developed. The Clq component of the first complement factor was precipitated out of the samples with a 0.02 M sodium acetate solution. Ahquots of the supernatants were dried, vapor hydrolyzed with 6 M hydrochloric acid at 105°C for 24 hours and derivatized with phenylisothiocy...
