Effects of Virtual Reality Content on Anxiety During Third Molar Surgery
Sponsor: Recep Tayyip Erdogan University
Summary
This randomized controlled study evaluated whether the content of an immersive virtual reality environment influenced anxiety in adults undergoing surgical removal of an impacted mandibular third molar. A total of 75 patients aged 18-40 years with elevated dental anxiety were randomly assigned in a 1:1:1 ratio to a nature-based virtual reality group, an art-gallery virtual reality group, or a control group receiving conventional care without virtual reality. Participants in the two virtual reality groups wore the same headset and headphones and viewed standardized 360-degree content from the beginning of surgery until completion of the procedure. Anxiety was assessed using the Modified Dental Anxiety Scale, the State-Trait Anxiety Inventory-State subscale, and an 11-point numerical anxiety rating scale. Systolic and diastolic blood pressure, heart rate, and peripheral oxygen saturation were also recorded. Measurements were obtained before local anesthesia, after local anesthesia but before surgery and virtual reality exposure, and immediately after wound closure, as applicable. The study compared changes in anxiety and physiological measures among the three groups and examined whether nature-based and art-gallery virtual reality content produced different responses.

Interventions
Nature-Based Virtual Reality
Participants viewed standardized investigator-developed nature-based 360-degree immersive content using a virtual reality headset and headphones. The intervention began at the start of surgery and continued until completion of the procedure. Exposure duration was determined by surgical duration and did not exceed 30 minutes.
Art-Gallery Virtual Reality
Participants viewed standardized investigator-developed art-gallery 360-degree immersive content using the same virtual reality headset, headphones, audiovisual settings, and exposure period as the nature-based virtual reality group. The intervention began at the start of surgery and continued until completion of the procedure. Exposure duration was determined by surgical duration and did not exceed 30 minutes.
