Gum thickening breakthrough? Platelet-Rich fibrin shows promise
NCT ID NCT06964529
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether two forms of platelet-rich fibrin (I-PRF and C-PRF) can help thicken thin gums in 30 healthy adults undergoing a specific gum surgery technique. The researchers measured changes in gum thickness and the width of attached gum tissue using both manual and digital methods. The goal was to see if these natural blood-derived products could improve the gum's appearance and health.
