New needle technique aims to make dental visits less painful for kids with weak enamel
NCT ID NCT07239050
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a special injection method (combining a standard numbing shot with a very short needle into the jawbone) works better than usual methods to control pain during dental treatment in children aged 6–12 with molar incisor hypomineralization (weak, sensitive enamel). About 26 healthy, cooperative children will take part. The goal is to see if this approach reduces pain and anxiety, making dental care easier for kids.
