Osteoprotegerin in Gingival Crevicular Fluid under Long-term Continuous Orthodontic Force Application

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...

Effect of Periodontal Surgery on Osteoprotegerin Levels in Gingival Crevicular Fluid, Saliva, and Gingival Tissues of Chronic Periodontitis Patients

OBJECTIVES This study was undertaken to investigate the OPG profiles in gingival crevicular fluid (GCF), saliva, and gingival tissues of chronic periodontitis (CP) patients in response to open flap debridement (OFD). SUBJECTS AND METHODS The study included 30 subjects divided into 2 groups: 20 CP patients and 10 periodontally healthy subjects. Plaque index, gingival index, pocket depth, and c...

Juveniles versus adults: differences in PGE2 levels in the gingival crevicular fluid during orthodontic tooth movement.

This study aimed to investigate age-related changes in the biosynthetic capacity of prostaglandin E2 (PGE2) in the gingival crevicular fluid (GCF) during one month of orthodontic treatment. Twenty-five juvenile subjects (mean age 13 +/- 2.1 years) and 23 adults (mean age 24 +/- 2.1 years) were included. GCF was collected immediately before the force application at the baseline, 2, 21 and 28 day...

Lactate Dehydrogenase Activity in Gingival Crevicular Fluid as a Marker in Orthodontic Tooth Movement

OBJECTIVES This study aims at analyzing the changes in gingival crevicular fluid (GCF) lactate dehydrogenase (LDH) activity during orthodontic movement. METHODS Twenty patients all requiring first premolar extractions were selected and treated with conventional straight wire mechanotherapy. Canine retraction was done using 125 g Nitinol closed coil springs. The maxillary canine on one side se...
