Brushing twice a day with fluoride toothpaste is one of the most effective ways to prevent it, but preschool children cannot do this properly on their own and depend on their mothers to brush for them and to supervise them. Mothers usually receive oral health advice only once, during a dental visit, and a single session may not be enough to change daily habits at home.\n\nThis study will test whether short oral health messages sent to mothers on WhatsApp, in addition to the usual face-to-face advice, help mothers know more about toothbrushing and help their children brush better.\n\nMothers of children aged 3 to 6 years attending the Pediatric Dentistry Clinics at King Abdulaziz University Hospital in Jeddah will be invited to take part. All mothers will first answer a short questionnaire about what they know about toothbrushing and how their child currently brushes. All mothers will then receive the same 10 to 15 minute face-to-face oral health education session. After the session, each mother will be placed into one of two groups by chance, like flipping a coin. Mothers in the first group will also receive two WhatsApp messages a week for eight weeks, sixteen messages in total, covering how often to brush, how much fluoride toothpaste to use, correct brushing technique, and how to help and supervise their child. Mothers in the second group will not receive these messages.\n\nAfter eight weeks, all mothers will answer the same questionnaire again, and the answers of the two groups will be compared. Taking part involves no dental treatment or procedures beyond the child's normal care, and mothers may withdraw at any time.",[64,65,66,67,68],"Oral Health","Dental Caries","Health Behavior","Oral Hygiene","Early Childhood Caries (ECC)",[70,71,72,73,74,75,76,77,78],"WhatsApp","mHealth","Mobile Health","Toothbrushing","Preschool Children","Maternal Knowledge","Oral Health Education","Health Promotion","Saudi Arabia","NOT_YET_RECRUITING","2026-08-17",{"date":82,"type":83},"2026-08-18","ACTUAL",{"date":85,"type":58},"2026-08-30",{"date":87,"type":58},"2027-08-30",{"name":5,"class":6}]
