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.

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.
