Study summary

Local anesthesia injections are sometimes painful, resulting in antagonistic cooperation, fear, and anxiety in children. This study aims to investigate the effectiveness of vibratory and cold stimulation before the injection to reduce pain. Purpose of the study: Evaluate the effectiveness of Buzzy® in pain reduction during local anesthesia administration compared to the traditional topical anesthetic gel in pediatric patients.

What researchers measure

Primary outcomes

  1. Change in pain scores

    Visual Analogue Scale is used and it ranges from 0 to 10. the ''0'' point indicates ''no pain'' and ''10'' point indicates the worst possible pain.

    Time frame: Baseline and up to 1 hour

  2. Change in child's behavior

    Sound, eye,motor (SEM) scale is used. it assess child's pain perception by observing discomfot levels on SEM during injections. Total scores for SEM range from 0 to 9 based on 0-3 score for each parameter. Score 0: Comfort Score 1: Mild disocomfort Score 2: Moderate discomfort Score 3: Severe discomfort

    Time frame: During the procedure
