NCT ID NCT06874244

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This study compared two ways to numb teeth for dental procedures: a standard needle injection and a needle-free device that uses a mild electric current to deliver numbing medicine through the gums. Twenty adults took part, and researchers measured pain and anxiety with each method. The goal was to see if the needle-free approach could be a less frightening alternative.

Active substance

lidocaine hydrochloride and tetracaine/oxymetazoline

What this could lead to

If successful, this could offer a less scary, needle-free option for numbing teeth during dental procedures.

This is a very small, early-phase study with only 20 people. The needle-free method may not work as well or last as long as a standard shot.
