The goal of this clinical trial is to learn if Turkish classical music, patient-selected music, and silence have an effect on psychological and physiological anxiety indicators during orthodontic bracket placement. The main questions it aims to answer are: Does Turkish classical music reduce anxiety levels in orthodontic patients undergoing bracket placement? Does patient-selected music reduce anxiety levels in orthodontic patients undergoing bracket placement? Researchers will compare two different music genres to a control (no music, silence) to see if music therapy works to lower anxiety. Participants will: Listen to Turkish classical music or patient-selected music or silence during orthodontic bracket application and complete 2 scales before and after the intervention.
