Evaluation of the Dental Vibe Injection Comfort System — DVRCT  

Pain Clinical Trial

Official title:
Evaluation of the Dental Vibe Injection Comfort System

Clinical Trial Summary

This study investigated the Dental Vibe Injection Comfort System (DV), developed to lessen anesthesia pain through pulsed vibration, a form of counter-stimulation. The study's aims were to evaluate DV's efficacy in reducing pain/discomfort from intra-oral long buccal (LB) and inferior alveolar nerve (IAN) injections and the time needed to achieve complete anesthesia during an IAN block.

Clinical Trial Description

Objective: Pain from local anesthesia injections can be reduced by distraction and counter-stimulation techniques. This study investigated the Dental Vibe Injection Comfort System (DV), developed to lessen anesthesia pain through pulsed vibration, a form of counter-stimulation. Design: Our study's aims were to evaluate DV's efficacy in reducing pain/discomfort from intra-oral long buccal (LB) and inferior alveolar nerve (IAN) injections and the time needed to achieve complete anesthesia during an IAN block. Methods: The sixty subjects, equally split by sex, ages 21-32, rated injection pain on a visual analog scale and discomfort, unpleasantness, and difficulty in enduring the injection on a modified symptom severity index. Each subject received bilateral LB injections and an IAN block. Using block design, DV Generation 3 (DV3) was randomly assigned to either the first or second LB injection and to thirty subjects on their third injection, the IAN block. No topical anesthesia was applied. ;
