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.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
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.
What could go wrong
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.
