Biochemical assay of gingival crevicular fluid in industrial periodontal examination.

The HPLC assay of concentration of azithromycin from two different manufacturers in gingival crevicular fluid (GCF)

Background: Azithromycin (AZM) is used in periodontal infections. The present study compared gingival crevicular fluid concentration of azithromycin of two pharmaceutical companies through the HPLC method. Methods: Two groups (n=15) of healthy volunteers participated in this study. The first group received an imported azithromycin (ImAZM) tablet (250 mg, PO) and the second group received an ...

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...

Oral Fluid-Based Biomarkers in Periodontal Disease – Part 2. Gingival Crevicular Fluid

Periodontal diagnosis and treatment plan are based on the assessment of probing depth, clinical attachment level, plaque index, gingival index, bleeding on probing, suppuration, furcation involvement, mobility, and radiographic findings. However, these clinical parameters are not sufficiently sensitive and specific to identify disease activity in individual sites or to predict future attachment...

Effect of TNF-α Blockade in Gingival Crevicular Fluid on Periodontal Condition of Patients with Rheumatoid Arthritis

Background: Periodontitis and rheumatoid arthritis (RA) share a number of clinical and pathologic features, one of which is the presence of the tumor necrosis factor alpha (TNF-α)-induced bone resorption that is involved in the pathogenesis of both. Objectives: To investigate the effect of TNF-α blockade on periodontal conditions in patients with active RA. Method: The periodontal statuses of 3...
