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

This trial is comparing two methods of preparing young children for their first dental local anesthesia injection: a traditional approach called Tell-Show-Do (where the dentist explains and demonstrates what will happen) versus watching a video featuring an AI-generated avatar that explains the procedure in a child-friendly way. The goal is to see which method reduces anxiety and makes children more cooperative during the injection. **You may be eligible if:** - Your child is between 5 and 7 years old - Your child is in generally good health - Your child was cooperative during the dental examination - Your child has no known allergy to local anesthetics - This will be your child's first time receiving a dental local anesthesia injection - Your child needs non-urgent dental treatment under local anesthesia **You may NOT be eligible if:** - Your child has a history of epilepsy - Your child has been diagnosed with an anxiety disorder or behavioral disorder - Your child has a cognitive or developmental delay - Your child has significant hearing or visual impairment - Your child has previously received dental anesthesia - Your child requires a more complex nerve block (inferior alveolar nerve block) Talk to your doctor to see if this trial is right for you.
