Preventive Health Care

The goal of this study is to learn if educational videos sent through WhatsApp can improve dental health knowledge, healthy habits, and attitudes in primary school children aged 10 to 12 years in Cairo, Egypt. The main questions it aims to answer are: * Do children who receive dental health videos through WhatsApp have better knowledge about caring for their teeth after 8 weeks compared to children who do not receive the videos? * Do children who watch the videos brush their teeth more often and correctly, and make healthier food choices? * Do children who watch the videos feel more positive about taking care of their teeth and visiting the dentist? Researchers will compare children in Grade 5 who receive 6 short dental health videos through WhatsApp (one video per week for 6 weeks) to children in Grade 6 who continue their normal school activities to see if the videos lead to better knowledge, healthy habits, and more positive attitudes about dental health. Participants will: * Answer questions about their dental health knowledge, tooth brushing and eating habits, and feelings about dental care at the start of the study (takes about 15 to 20 minutes in a private room at school) * Children in Grade 5 will join a WhatsApp group and receive one short video (2 to 5 minutes) each week for 6 weeks about topics like why teeth are important, how to brush teeth correctly, which foods are goo

It is widely accepted that prevention is far more impactful than curative medicine and must be included in primary care. In a previous pilot study, we evaluated passive video preventive lifestyle education in the emergency department. The current study is a randomized prospective trial assessing the practicality and impact of a brief interactive educational video intervention to patients during primary care clinic visits.
