What this Trial Is About
This research aims to compare two behavior guidance methods to reduce anxiety in children during local anesthesia injections in dental care. It focuses on children aged 5 to 7 years who need local anesthesia for routine dental treatment. The study evaluates the traditional Tell-Show-Do technique against an artificial intelligence-driven avatar video called the "Mini Dentist" to see which better helps reduce fear and improve cooperation. Children will be randomly assigned to one of two groups. One group will watch the AI avatar video that explains and demonstrates the injection in a child-friendly way before the procedure. The other group will receive the conventional Tell-Show-Do method, where the dentist verbally explains and shows the procedure before performing it. All injections follow the same standardized protocol and are done by the same pediatric dentist. Participants will have their anxiety measured by monitoring heart rate at five specific times during the injection visit. Pain and behavior will also be assessed using the FLACC behavioral scale and the Wong-Baker FACES pain rating scale. Video recordings of behavior during the injection will be reviewed by trained evaluators. The study is voluntary and approved by an ethics committee, aiming to see if the AI-based method improves anxiety control and cooperation during dental injections.
