Dietary Supplementation With Low-Dose Omega-3 Reduces Salivary TNF-α Levels in Patients With Chronic Periodontitis

Early Phase 1

Completed

• Conditions: Chronic Periodontitis

• Registration Number: NCT02719587
• Lead Sponsor: İlker KESKINER

Brief Summary

The investigators primary objective in this clinical intervention study, therefore, was to explore the impact of omega-3 PUFAs in conjunction with scaling and root planing on salivary markers (in patients with chronic periodontitis.

Detailed Description

Thirty systemically healthy subjects with chronic periodontitis were enrolled and randomly allocated into two groups. The control group (n=15) was treated with scaling and root planing (SRP)+placebo whereas the test group (n=15) was treated with SRP and dietary supplementation of low-dose omega-3 PUFAs (6.25 mg EPA and 19.19 mg DHA). Clinical parameters were taken at baseline, 1, 3 and 6 months following therapy. Saliva samples were obtained at the same time intervals and analyzed for tumor necrosis factor-α (TNF-α) and superoxide dismutase (SOD).
