Effect of Alpha-Band Binaural Beats on Stress and Recovery in Third Molar Surgery

Sponsor: Alperen Kalyoncu

Summary

Preoperative anxiety and loud equipment noises, such as dental drills, create significant stress and autonomic fluctuations in patients undergoing oral surgery. Brainwave entrainment using alpha-band (10 Hz) binaural beats is a non-invasive audio method designed to promote relaxation and activate the parasympathetic nervous system. The purpose of this randomized controlled clinical trial is to evaluate the clinical effectiveness of a 10 Hz alpha-band binaural beat track embedded in continuous rain sound on reducing perioperative anxiety, maintaining hemodynamic stability, and improving postoperative recovery in patients undergoing impacted third molar extraction. Fifty-four healthy adult participants (ASA I) scheduled for impacted third molar surgery will be randomly assigned into three groups:Binaural Beats Group: Listening to 10 Hz alpha binaural beats embedded in a rain sound via active noise-cancelling (ANC) headphones during surgery. Placebo Group: Listening to rain sound only via ANC headphones during surgery. Active Control Group: Wearing ANC headphones with no audio broadcast (noise cancellation feature only). Preoperative dental anxiety, hemodynamic parameters (blood pressure, heart rate, oxygen saturation) at four distinct intraoperative stages, post-surgical stress levels, and 7-day postoperative pain/analgesic consumption will be measured and compared among the groups.
