3D-Printed crowns and new putty could change how Kids' cavities are treated
NCT ID NCT07344038
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at two new ways to treat deep cavities in children's second molars. It compares a bioceramic putty to a standard material for the nerve treatment (pulpotomy), and 3D-printed resin crowns to standard metal crowns. Sixty children aged 5 to 7 will be followed for a year to see which combination works best and keeps parents happy.
