Binaural auditory beats vs music of choice as audio distraction behaviour guidance technique among children: A randomized controlled trial.

Background: Binaural beat is created by presenting two different pure-tone sine waves with less than a 30Hz difference dichotically. In dental settings, children listening to familiar music during treatments gain control over the anxiety caused by tools like the airotor or syringe, creating a comforting, familiar environment. Aim: To evaluate and compare anxiety level during restorative treatment using No Music, Music of choice and Binaural Auditory Beats as Audio distraction behaviour guidance technique in children aged 6-12 years. Methods: In-vivo, double-blind, three-arm, parallel-group randomized study was conducted in the department of pediatric and preventive dentistry where 75 participants were allocated into 3 groups. The teeth with Class I cavity in primary and permanent molars were prepared and restored. Anxiety was measured pre- and post-intervention using Pulse oximeter and Venham's picture test. Results: Children who were treated with Binaural beats and Music of choice showed reduction in anxiety levels as indicated by lower anxiety scores in Venham picture test and pulse rate values as compared to the control group. Conclusion: Binaural auditory beats and Music of choice can be used effectively as a non-invasive treatment modality to reduce anxiety in apprehensive pediatric patients.
