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.
