Sonic zap eases kids' tooth pain, AI reads their faces
NCT ID NCT07138937
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested whether using a sonic device (EDDY) during root canal treatment in children's baby molars reduces pain afterward. Thirty children aged 5-8 with tooth infections received either sonic-activated cleaning or standard cleaning. Pain was measured using a face scale and an AI app that analyzed facial expressions. The goal was to see if sonic activation makes treatment more comfortable and if AI can help assess pain.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- EDDY system for sonic activation of irrigation
- What this could lead to
- If it works, this could make root canal treatments less painful for children and offer a new way to measure pain using AI.
- What could go wrong
- This is a small, completed study with only 30 children, so results may not apply to all kids. The AI app for facial expressions is still experimental.
