Effects of Virtual Reality Content on Anxiety During Third Molar Surgery

13. September 2026 aktualisiert von: İsmail Burak HALAT, Recep Tayyip Erdogan University

A Comparative Evaluation of the Effects of Different Virtual Reality (VR) Content on Patient Anxiety During Impacted Mandibular Third Molar Surgery

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.

Intervention / Behandlung
Experimental: Nature-Based Virtual Reality
Participants viewed standardized investigator-developed nature-based 360-degree immersive content using a virtual reality headset and headphones from the beginning of surgery until completion of the procedure. Exposure duration was determined by surgical duration and did not exceed 30 minutes.
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.
Experimental: 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. Exposure continued from the beginning of surgery until completion of the procedure and did not exceed 30 minutes.

Kein Eingriff: Conventional Care Without Virtual Reality
Participants underwent the same standardized surgical procedure and received conventional clinical care without a virtual reality headset or an alternative audiovisual intervention.

Maßnahmenbeschreibung
Zeitfenster
Change in Modified Dental Anxiety Scale Score
Zeitfenster: From before local anesthesia (T0) to immediately after wound closure and completion of the procedure (T2), during a single surgical visit
Dental anxiety was assessed using the five-item Modified Dental Anxiety Scale (MDAS). Each item is scored from 1 to 5, producing a total score ranging from 5 to 25, with higher scores indicating greater dental anxiety. The outcome was the change in total MDAS score from T0 to T2, calculated as the T2 score minus the T0 score.
From before local anesthesia (T0) to immediately after wound closure and completion of the procedure (T2), during a single surgical visit
Change in State-Trait Anxiety Inventory-State Subscale Score
Zeitfenster: From before local anesthesia (T0) to immediately after wound closure and completion of the procedure (T2), during a single surgical visit
State anxiety was assessed using the 20-item State-Trait Anxiety Inventory-State subscale (STAI-S). Each item is scored from 1 to 4, producing a total score ranging from 20 to 80, with higher scores indicating greater state anxiety. The outcome was the change in total STAI-S score from T0 to T2, calculated as the T2 score minus the T0 score.

Change in Anxiety Visual Analog Scale Score
Zeitfenster: At three time points during a single surgical visit: before local anesthesia (T0), after local anesthesia but before surgery and virtual reality exposure (T1), and immediately after wound closure and completion of the procedure (T2)
Momentary anxiety was assessed using the study-designated Anxiety Visual Analog Scale (VAS-A), administered as an 11-point whole-number response scale ranging from 0 to 10. A score of 0 indicated no anxiety, whereas a score of 10 indicated the highest perceived anxiety. Changes in VAS-A scores across T0, T1, and T2 were compared among the study groups.
