NCT ID NCT06227390
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 120 healthy children aged 4-7 with deep cavities in their baby molars. Dentists removed the decay and used one of three special materials to cover the nerve, then sealed the tooth with either a filling or a metal crown. The goal was to see which combination worked best to keep the tooth healthy and pain-free.
