Omega-3s and low-dose aspirin for smokers with stage III periodontitis
Official title: Clinical and Biochemical Evaluation of the Effect of Omega-3 Fatty Acids Plus Low-Dose Aspirin as an Adjunct to Non-Surgical Periodontal Therapy in Smoker Patients With Stage III Periodontitis: A Randomized Double-Blind Placebo-Controlled Clinical Trial
Run by Al-Azhar University · NCT07673185 · Data updated 2026-11-12
In adults who smoke and have stage III periodontitis, this study tests whether adding omega-3 fatty acids and a small amount of aspirin to standard cleaning helps improve gum health.

Is this trial a fit for you?
✓Likely a good fit
Smokers aged 30-50 with diagnosed stage III periodontitis, PPD ≥5 mm, CAL ≥5 mm, and at least 20 natural teeth who can provide informed consent.
✕Probably not a fit
Patients without improvements in periodontal measurements or who do not respond biochemically may not experience a benefit.

What this trial studies
This is a randomized, double-blind, placebo-controlled trial evaluating whether omega-3 fatty acids (EPA and DHA) plus low-dose aspirin as an adjunct to scaling and root planing can improve periodontal outcomes. Participants are smokers aged 30-50 with stage III periodontitis and at least 20 teeth, assigned to receive either the omega-3/aspirin combination or placebo after SRP, with follow-up at 3 and 6 months. Primary endpoints include changes in probing pocket depth and clinical attachment level; secondary endpoints include inflammatory biomarkers such as IL-1β in gingival crevicular fluid and other clinical parameters. The study measures both clinical and biochemical responses to host-modulation therapy in this high-risk population.
Why it matters
Potential benefit: If successful, the approach could offer a new adjunctive strategy to improve periodontal healing in smokers.
How similar studies have gone: Previous work suggests omega-3 fatty acids may have anti-inflammatory benefits in periodontal disease, but results vary and this specific combination with low-dose aspirin in smokers is relatively novel.
