Tooth healing breakthrough: size matters in root canal regeneration
NCT ID NCT07466433
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether making a larger opening at the tip of the tooth root helps regenerative dental treatment work better for adults with infected mature teeth. 36 people received one of two treatment sizes and were followed for healing and pain. The goal was to see which size leads to better infection clearance and tooth recovery.
