Maxillary Lateral Incisor Injection Pain Using the Dentapen Electronic Syringe.

Introduction: When patients express fear and anxiety about dentistry, 1 main source involves the administration of local anesthetic. The Dentapen (Septodont, Lancaster, PA) is a computer-controlled local anesthetic device that regulates the rate of anesthetic deposition to reduce pain associated with dental injections. The purpose of this study was to evaluate differences in perceived pain during the administration of local anesthesia of the maxillary lateral incisors using the ramp-up and continuous injection modes of the Dentapen.
