Sensory-Adapted Dental Clinics Help Reduce Children's Anxiety, Study Shows
A new study reveals that multi-sensory dental environments based on Snoezelen principles can significantly reduce anxiety and heart rates in children during treatments.
A recent study published in the International Journal of Clinical Pediatric Dentistry explores whether adapting the dental clinic environment using Snoezelen multi-sensory principles can help alleviate children's dental anxiety. Conducted with 60 children aged 6 to 12, the research compared a standard dental environment with a sensory-adapted setting.
Anxiety levels and heart rates were measured before and after the dental procedure. The findings revealed significantly lower anxiety scores and reduced heart rates among children treated in the sensory-adapted environment compared to the control group. However, researchers noted that this was a small-scale study focusing on immediate physiological responses, leaving open the question of whether such interventions can alleviate long-term fear or suit every child.
Snoezelen is a multi-sensory approach developed in the Netherlands during the 1970s by Jan Hulstaert and Ad Verheul, initially for individuals with intellectual disabilities. These specialized rooms feature bubble columns, fiber optics, projections, sounds, and textured surfaces designed to promote relaxation, exploration, and sensory engagement at an individual pace.
Experts emphasize that not all multi-sensory interventions follow the exact same protocol, and equipment, supervision, and objectives vary widely across studies. A 2025 systematic review of multi-sensory environments for autistic children and adults indicated potential benefits, but underscored that current evidence remains limited due to small sample sizes and methodological differences.
Proper implementation requires personalization rather than generic stimulation. Ilan Elbaz, head of the Snoezelen division at Peulatton, points out that the approach centers on listening to the individual and adjusting the environment accordingly. Control over sensory stimuli, the ability to dim lights or lower sounds, and professional guidance are critical factors in ensuring a positive and therapeutic experience.
