Comparative Effectiveness of Virtual Reality Distraction Versus Audio Distraction in Special Care Dentistry Patients

Abstract

Background: Dental anxiety is a pervasive barrier to oral healthcare in special care dentistry patients, including individuals with physical disabilities, intellectual disabilities, and systemic medical conditions. Distraction techniques have gained recognition as non-pharmacological adjuncts for managing procedural anxiety. Virtual reality (VR) distraction, leveraging immersive audiovisual technology, and audio distraction, employing music or nature sounds through headphones, represent two widely employed modalities with differing mechanisms and degrees of sensory engagement.

Objective: To compare the effectiveness of virtual reality distraction versus audio distraction in reducing dental anxiety, pain perception, and improving procedural cooperation among special care dentistry patients.

Methods: A randomized controlled clinical trial was conducted among 60 special care dentistry patients aged 18–55 years, randomly assigned to virtual reality distraction (Group I) or audio distraction (Group II) during routine dental procedures. Dental anxiety was assessed using the Modified Dental Anxiety Scale (MDAS), pain perception using a Visual Analogue Scale (VAS), and heart rate was monitored as a physiological anxiety marker. Assessments were recorded at baseline, during the procedure, and at post-procedural follow-up.

Results: Group I (VR distraction) demonstrated significantly greater reductions in MDAS anxiety scores, lower VAS pain ratings, and more stable heart rate profiles compared to Group II (audio distraction). VR distraction reduced mean MDAS scores by 48% versus 22% in the audio distraction group at post-procedural assessment.

Conclusion: Virtual reality distraction is significantly more effective than audio distraction in reducing dental anxiety and pain perception in special care dentistry patients. VR distraction represents a promising, non-pharmacological, patient-centered adjunct for improving the dental experience in this vulnerable population.
