Gum treatment may cool artery inflammation after heart attack

NCT ID NCT04046237

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study tests whether treating severe gum disease can reduce inflammation in the arteries of people who have recently had a heart attack. 210 participants will be randomly assigned to receive either intensive periodontal treatment or standard dental care. The main goal is to see if the treatment lowers inflammation in the carotid arteries, measured by PET scans at the start and after 12 months.

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 (deep cleaning, root scaling, antiseptic irrigation)

What this could lead to

If it works, this could show that treating gum disease lowers artery inflammation, potentially reducing the risk of future heart attacks.

What could go wrong

This is an early-stage study focused on a biomarker (inflammation on PET scans), not on actual heart attack rates. The treatment is intensive and may not be practical for all patients.
