Summary

This study looked at how vaping and traditional smoking affect gum healing after a deep dental cleaning in people with stage II gum disease. Researchers measured gum pocket depth, bleeding, and inflammation markers in 117 participants. The goal was to see if vaping is less harmful than smoking for gum recovery.

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 therapy (scaling and root planing)
What this could lead to
If successful, this study could clarify whether vaping is less harmful than smoking for gum disease recovery.
What could go wrong
This is a completed observational study, not a treatment trial. Results may not apply to all patients and do not test a new therapy.
