The Effıcacy of External Cooling and Vibration on Decreasing the Pain of Local Anesthesia Injections During Dental Treatment in Children: A Randomized Controlled Study

Abstract

Purpose: This study was performed to assess the efficacy of external cooling and vibration devices on the pain of injections applied to the site of local anesthesia in children during dental treatment.

Design: This study is a randomized controlled trial.

Methods: This study was conducted with 60 children requiring mandibular baby teeth extraction. The children in the experimental group were anesthetized after cold application, and a vibration device was administered on the application site 2 minutes before and during the anesthesia process, whereas those in the control group were only given local mandibular anesthesia without any other procedure.

Findings: It was found that the mean pain score was lower in the experimental group with a significant difference between the groups (P < .05).

Conclusions: This study found that the application of external cooling and vibration on the site of local anesthesia had a significant effect on the injection pain experienced by children during dental treatment.
