Randomized trial compares noise types for managing dental anxiety in children undergoing extractions, suggesting effective techniques.
Abstract Background: Audio-analgesia is one of the unexplored aspects of behaviour management in pediatric dentistry, and recently, there have been many new inclusions in shades of noise that were previously just limited to white noise, like brown noise and pink noise. Aim: The aim of the study was to evaluate and compare the effectiveness of white noise, brown noise, and pink noise on dental anxiety in pediatric patients undergoing primary tooth extraction. Study Settings and Design: This study was designed as a randomised, controlled trial at an academic pediatric dental department. Forty children aged 8-12 years scheduled for extraction were randomly assigned into four groups. Materials and Method: Forty participants were evenly divided into four groups: Group A (white noise), Group B (pink noise), Group C (brown noise), and Group D (No intervention), For all the participants, the anxiety rate, pulse rate and pain score was evaluated using Venham’s Picture Test, a pulse oximeter and Visual Analog Scale (VAS) both preoperatively and postoperatively. Results: All groups had shown significant differences in dental anxiety and pain, preoperatively and postoperatively, but pink noise was found to be effective even in maintaining pulse rate intraoperatively. Conclusion: In pediatric dentistry, audio distraction using pink noise found to be innovative, noninvasive, and effective behavior management technique that can effectively manage dental anxiety in children. Key Words: Anxiety, audio analgesia, brown noise, distraction, pink noise, white noise
