Mouth ridge ID tested after dental expansion
NCT ID NCT07667933
First seen Jun 27, 2026 · Last updated Aug 14, 2026 · Updated 2 times
Summary
This study looked at whether the unique ridges on the roof of the mouth (palatal rugae) can still be used to identify a person after they have had dental expansion treatment. Researchers used 3D scans from 45 people before and after treatment to see if the ridges remained distinct. The goal is to help forensic experts identify individuals even after dental changes.

- What this could lead to
- If successful, this could improve forensic identification methods for people who have undergone dental expansion procedures.
- What could go wrong
- This is a small, completed study with only 45 participants, so results may not apply broadly. The technique may not be reliable enough for real-world forensic use.
