About this study
Official title: A Comparative Study of Virtual Reality and Sensory-Adapted Dental Environments for Dental Anxiety Reduction in Individuals With Borderline Intellectual Functioning
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.
- Being tested
- Virtual Reality Distraction - immersive VR software delivered through Meta Quest 3® headset during dental procedure, Sensory adapted dentist environment

Questions about this trial
What is this clinical trial studying?
A study testing Virtual Reality Distraction - immersive VR software delivered through Meta Quest 3® headset during dental procedure and Sensory adapted dentist environment in people with Borderline Intellectual Functioning (BIF), run by Oasi Research Institute-IRCCS at 1 site in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Treatment success (time frame: Duration of procedure). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Dec 2025.
