Gum treatment may lower lung flare-ups in bronchiectasis patients
NCT ID NCT02514226
First seen Jul 29, 2026 · Last updated Jul 30, 2026 · Updated 1 time
Summary
This trial tests whether treating gum disease can reduce bacteria that cause lung infections in people with bronchiectasis. Participants with both conditions will receive either basic cleaning, deep cleaning, or deep cleaning plus light therapy. Researchers will measure bacteria in saliva, gum pockets, sputum, and nasal fluid over one year to see if gum treatment lowers the risk of lung flare-ups.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- periodontal treatment (scaling and root planing with or without photodynamic therapy)
- What this could lead to
- If successful, this approach could offer a way to reduce lung infections and hospital visits in people with bronchiectasis by treating gum disease.
- What could go wrong
- This is a small, early-stage trial with only 30 participants per group, so results may not apply to everyone. The benefit for lung health is uncertain, and the procedures may cause temporary gum discomfort.
