Study summary

Research on dental phobia highlights both external causes, like traumatic experiences or media influence, and internal factors, such as genetics and personality traits. While many studies focus on technical aspects of dental care, few explore how the care environment affects patient anxiety.

The Snoezelen concept, developed in the 1970s, uses sensory stimulation (sight, sound, smell, and touch) to reduce anxiety. Initially designed for individuals with neurocognitive disorders, it creates a calming environment and has since been adopted in various healthcare settings.

At Nantes University Hospital, the dental department will test the Tovertafel Pixie®, a sensory projector designed to distract patients and reduce anxiety. Its mobility allows it to be used in waiting rooms and treatment areas, projecting onto ceilings, walls, or tables. This real-life study will assess whether patients exposed to the projector experience less anxiety compared to those who are not, with the goal of improving patient care and dental treatment experiences.

Read the detailed description

The study involves a questionnaire that the dental department usually provide to our patients, which is partially completed by the patient and partially by the practitioner at the end of the treatment session. No follow-up visit is required.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 24, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
