Anxiety, affecting 10-20% of children, poses a barrier to care. This issue is exacerbated by deinstitutionalization and the law for equal rights, exposing orthodontists to a new patient group combining disability-related traits and heightened anxiety. Faced with anxious children, orthodontists have various management strategies. However, conventional behavioral techniques (CBT) have shown limits in children with neurodevelopmental disorders (NDD), contributing to disparities in access to care. Practitioners' reluctance to treat these patients underscores the need for ongoing training and tailored approaches. Emerging techniques combining virtual reality (VR) and hypnosis have proven effective in reducing anxiety in children. However, their effectiveness in children with NDD remains underexplored, despite independent successes of hypnosis and VR in other contexts.</p><p><strong>Material and methods: </strong>In this context, we conducted a prospective randomized controlled trial at Bretonneau Hospital to evaluate the effectiveness of VR distraction in children aged 6 to 18 with NDD during orthodontic assessments.</p><p><strong>Results: </strong>The results indicate that VR distraction is similarly effective to CBT in reducing anxiety, although the small sample size may limit the generalization of these results.
