Comparative Clinical Study Between Virtual Reality Hypnosis and Nitrous Oxide Inhalation for Dental Anxie

The vicious circle of dental anxiety impacts major aspects of a child's quality of life. Hypnosis using distraction is one of the most common non-pharmalogical techniques in behavior and pain management in pediatric dentistry. Its value over traditional pharmalogical sedation is undeniable. This clinical study examines the application of hypnosis delivered through immersive virtual reality (VR) for anxious children ongoing dental procedures. The investigators will explore whether VR is as effective on pain and anxiety relief as a pharmacological sedation with inhalation of nitrous oxide.
