Potential Factors Which Affect Gingival Crevicular Fluid Sampling Procedures

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.

Analysis of factors that may affect the enzymatic profile of gingival crevicular fluid: sampling technique, sequential sampling and mode of data presentation.

To evaluate the possible effect of sampling technique and sequential sampling on gingival crevicular fluid (GCF) volume and myeloperoxidase (MPO) activity, 14 patients presenting at least two symmetrical maxillary sites with mild/moderate periodontitis were selected. Two sites in each individual were sequentially sampled using either the deep-intracrevicular or orifice technique. Spectrophotome...

Periodontal pathogens affect the level of protease inhibitors in gingival crevicular fluid.

In periodontitis, an effective host-response is primarily related to neutrophils loaded with serine proteases, including elastase (NE) and protease 3 (PR3), the extracellular activity of which is tightly controlled by endogenous inhibitors. In vitro these inhibitors are degraded by gingipains, cysteine proteases produced by Porphyromonas gingivalis. The purpose of this study was to determine th...
