Pig or cow? study tests which collagen dressing heals tooth holes best

NCT ID NCT05802602

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study compared two collagen wound dressings—one from pigs and one from cows—placed in tooth extraction sites along with a bone graft. Nineteen non-smoking adults aged 19-65 who needed a premolar or front tooth pulled took part. Researchers measured soft tissue thickness and bone density changes to see which dressing worked better.

What this could mean

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

Active substance

porcine collagen membrane and bovine collagen wound dressing

What this could lead to

If one dressing works better, it could improve healing and bone quality after tooth extraction and grafting.

What could go wrong

This is a small, completed study with only 19 participants, so results may not apply to everyone. The dressings are already available, so no major breakthrough is expected.
