A Comparative Study of Virtual Reality and Sensory-Adapted Dental Environments for Dental Anxiety Reduction in Individuals With BIF

NCT07261670 | Completed

• 1 other identifier: RC-2794677_
• Study Type: interventional
• Target: 98
• Locations: 1 country
• Sites: 1

Brief Summary

A randomized clinical trial was conducted with 98 participants with borderline intellectual functioning (BIF) and moderate dental anxiety (DAS: 9-12). Participants were assigned in a 1:1 ratio to either the Virtual reality (VR) or sensory adapted dentist environment (SADE) group (49 per group). The primary outcome was treatment success, defined as completing a dental restoration under local anesthesia within 30 minutes.

Conditions

Borderline Intellectual Functioning (BIF)

Outcome Measures

Primary Outcomes (1)

• Treatment success

  Completion of restorative dental procedure under local anesthesia within 30 minutes and positive overall treatment experience (dichotomous: success vs. failure)

  Duration of procedure

Study Arms (2)

Virtual Reality Distraction

EXPERIMENTAL

immersive VR software delivered through Meta Quest 3® headset during dental procedure

Device: Virtual Reality Distraction - immersive VR software delivered through Meta Quest 3® headset during dental procedure

Sensory adapted dentist environment Control

ACTIVE COMPARATOR

Sensory adapted dentist environment designed to reduce sensory stimuli with: * soft and dim lighting * a screen projecting familiar movies, cartoons, or videos previously provided by the family * a dental turbine handpiece covered with a sponge layer to minimize noise

Device: Sensory adapted dentist environment
