NCT ID NCT07339670

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looked at how smoking affects gum healing after non-surgical treatment for stage II gum disease. Researchers measured two proteins (PLAP-1 and Sclerostin) in the gum fluid of 36 patients—both smokers and non-smokers—before and after deep cleaning. The goal was to see if smoking changes the body's healing response at a molecular level.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Non-surgical periodontal treatment (scaling, root planing, and Listerine mouthwash)

What this could lead to

If successful, this study could reveal how smoking interferes with gum healing, potentially leading to better treatment approaches for smokers with gum disease.

What could go wrong

This is a small, completed observational study with only 36 participants. It measures protein levels rather than long-term health outcomes, so results may not directly change treatment.
