through WhatsApp can improve dental health knowledge, healthy habits, and attitudes in primary school children aged 10 to 12 years in Cairo, Egypt.\n\nThe main questions it aims to answer are:\n\n* 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?\n* Do children who watch the videos brush their teeth more often and correctly, and make healthier food choices?\n* Do children who watch the videos feel more positive about taking care of their teeth and visiting the dentist?\n\nResearchers 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.\n\nParticipants will:\n\n* 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)\n* 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
