What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of the study is to evaluate two different ways to administer the numbing solution. One is with a conventional needle and syringe the other method iontophoresis is a machine that supplies a weak current through electrodes that touch your teeth. Both methods use an anesthesia solution to make your teeth numb but the iontophoresis system contains no needle and the delivery device does not penetrate the gum.

Are You a Good Fit for This Trial?

This trial is for individuals who need local anesthesia for dental procedures and are willing to try two different numbing methods. One method uses a needle and syringe, while the other uses a machine called iontophoresis that delivers the anesthetic through electrodes without penetrating the gums.

What Are the Treatments Tested in This Trial?

Interventions

• Iontophoresis of Tetracaine and oxymetazoline
• Local Anesthesia (lidocaine hydrochloride)

Trial Overview The study compares traditional needle-and-syringe delivery of lidocaine (a common numbing medication) with a no-needle technique using iontophoresis to administer tetracaine and oxymetazoline. The goal is to see which method provides effective dental anesthesia with less pain during administration.

How Is the Trial Designed?

Group I: Iontophoresis of Tetracaine and oxymetazoline Experimental Treatment 1 Intervention

Group II: Local Anesthesia (lidocaine hydrochloride) Active Control 1 Intervention
