Dietary Supplementation With Low-Dose Omega-3 Fatty Acids Reduces Salivary TNF-α Levels in Patients With Chronic Periodontitis
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.
研究概览
详细说明
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).

Control group (8 males, 7 females; 42.54±5.82
years) (SRP): SRP followed by administration of a placebo.
The placebo was identical except for the fish oil.

placebo drug identical except for the fish oil supplement, were only performed at baseline.
Instrumentation was performed until the root surface was considered smooth and clean, according to the operator's clinical judgement.

有源比较器：test group
Test group (8 males, 7 females; 40.87±9.7 years) (SRP+omega-3 PUFAs): SRP followed by omega-3 PUFAs supplementation.
The test drug contained omega-3 PUFAs including 6.25 mg EPA and 19.19 mg DHA obtained from the Atlantic salmon Salmo salar.Both test and placebo drugs were taken twice a day by the patients for six months.
Subjects came to the clinic every 4 weeks during the 6 month course of the experiment to replenish their medication.
Remaining medications were checked for compliance.
At each evaluation visit (1, 3 and 6 months), oral soft and hard tissue examinations and adverse-event evaluations were performed.
