New dental gadget aims to make Kids' tooth pulls Pain-Free
NCT ID NCT07156032
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study compares a computer-controlled injection device (Starpen) to a standard syringe for numbing and extracting upper baby molars in 38 children aged 6-8. The goal is to see if the new device causes less pain during the injection. Children will rate their pain using a faces scale, and researchers will also observe pain behaviors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- articaine HCL 4% with epinephrine 1:100,000
- What this could lead to
- If it works, this could point toward a less painful way to give dental injections to children, making dental visits easier for kids and parents.
- What could go wrong
- This is a small, early-stage trial with only 38 children, so results may not apply to all kids or settings. The device may not significantly reduce pain compared to a standard syringe.
