Vibrating gadgets aim to take the ouch out of kids' dental needles
NCT ID NCT07571278
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether two vibrating devices (Vibraject and Dental Vibe) can reduce pain in children aged 6-8 when they receive a numbing injection for dental work. 90 children will be randomly assigned to get the injection with a vibrating device or a standard syringe. Pain will be measured using child-reported and observer-rated scales. The goal is to find a more comfortable way to deliver local anesthesia.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Vibraject and Dental Vibe vibrating devices
- What this could lead to
- If successful, this could give dentists a simple, drug-free way to make numbing injections less painful for children.
- What could go wrong
- This is a small, early-stage trial (90 children) testing a device, not a new drug. Results may not apply to all children or dental procedures, and the devices may not reduce pain significantly.
