Summary

This study looks at whether sending short dental health videos through WhatsApp can improve how much 10-12 year old children in Cairo know about taking care of their teeth, and whether it changes their brushing and eating habits. About 150 children will take part, with one group watching the videos and the other group continuing as usual. The goal is to see if a simple, phone-based approach can make a difference in dental health knowledge and practices.
