New 3D device aims to take the pain out of dental needles
NCT ID NCT06676098
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new 3D-printed device that helps dentists give numbing injections more accurately for procedures on lower teeth. Traditional numbing methods fail up to 45% of the time, causing discomfort. The device uses a 3D scan to guide the needle to the right spot, aiming to improve success and reduce pain. Ten adults needing root canal treatment on lower teeth will try it, and researchers will ask how well it worked and if it was safe.
