Blood clot vs sponge: which heals wisdom teeth better?
NCT ID NCT07530068
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether placing platelet-rich fibrin (PRF) made from the patient's own blood or an absorbable collagen sponge into the socket after wisdom tooth removal improves healing. Twenty-nine healthy adults with impacted lower wisdom teeth on both sides took part. Each side received one of the two treatments, and the researchers measured bone healing, pain, and swelling afterward.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Platelet-rich fibrin (PRF) and absorbable collagen sponge
What this could lead to
If PRF proves better, it could become a standard way to improve healing and reduce pain after wisdom tooth extraction.
What could go wrong
This is a small, completed study with only 29 participants, so results may not apply to everyone. The benefits of PRF over collagen sponge may be minor.
