Alpha-Band Binaural Beats During Third Molar Surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this randomized, controlled trial, adults undergoing impacted mandibular third molar extraction are assigned to three groups: binaural beats with rain sound and active noise cancellation, rain sound with no binaural beats (placebo), and active noise cancellation alone. The aim is to see if the 10 Hz alpha-band binaural beats help lower perioperative anxiety, stabilize vital signs, and enhance postoperative recovery compared with control conditions. Outcome assessors and statisticians are blinded to group assignments, while participants are blinded to the specific hypothesis. All procedures are performed by a single experienced surgeon under standardized conditions. The study uses MDAS scores preoperatively and perioperative measurements to evaluate effects.
