Gingival Crevicular Fluid Biomarkers

چکیده
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 recorded before and after the treatments. The MMP-8 and TIMP-1 levels in GCF samples collected on days 0 and 49 were determined by using the enzyme-linked immunosorbent assay. Results: All groups showed significant reductions in plaque index, sulcus bleeding index and probing depth (p<0.01). Although attachment gain was observed in all groups, only the gain in the SRP plus local metronidazole group was significant (p<0.05). The GCF MMP-8 levels decreased significantly (p<0.05), whereas the GCF TIMP1 levels increased. No significant differences were found between the groups.

متن کاملGingival Crevicular Fluid as a Novel Potential Source of Biomarkers Distinguishes Pubertal from Post-Pubertal Subjects
Detection of pubertal growth peak is vital in orthodontic treatment timing and planning. Gingival crevicular fluid (GCF) contains abundant proteins from different sources and has been proven to be an ideal source of biomarkers. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/MS) is an advanced technique that can detect low-molecular-weight peptides with h...
