AI Avatar Video vs. Tell-Show-Do for Reducing Anxiety and Improving Cooperation in Children During Local Anesthesia

This randomized clinical trial aims to compare two behavior guidance techniques used to reduce anxiety in children during local anesthesia injections in dental treatment. The study evaluates the traditional Tell-Show-Do (TSD) technique versus an artificial intelligence (AI)-driven, avatar-based video method called the "Mini Dentist." Children aged 5 to 7 years who require local anesthesia for routine dental treatment will be randomly assigned to one of two groups. The control group will receive the conventional Tell-Show-Do explanation from the pediatric dentist. The experimental group will watch a short animated video featuring an AI-generated avatar that explains and demonstrates the procedure in a child-friendly manner before the injection. Anxiety and behavior will be assessed using heart rate monitoring, behavioral observation (FLACC scale), and a self-reported pain scale (Wong-Baker FACES). The goal is to determine whether the AI-based method improves cooperation and reduces anxiety compared to the traditional approach. Participation is voluntary, and all procedures follow ethical research standards.
