Reminder-based Educational Mobile Intervention for for Maternal Oral Health Literacy and Preschoolers' Dental Health

The goal of this clinical trial is to determine the effectiveness of educational application based on notification and reminder in improving maternal oral health literacy and the dental and dental health status of preschool children among mother-preschool child pairs (children aged \<7 years) in Pancoran Mas, Depok City. The primary research questions to be addressed in the main trial are: * Does the application group improve mothers' oral health literacy (measured using the REALD-30 questionnaire) more than the printed booklet group? * Does the application group improve children's oral health status, as measured by oral hygiene (Debris Index-Simplified \[DI-S\]) and gingival condition (modified Gingival Index \[mGI\]), more than the printed booklet group? * What is the level of usability (ease of use) of the application as perceived by mothers who use it? The researchers will compare a group of mothers who receive education through the application with a group of mothers who receive education through a printed booklet to determine whether the application produces greater improvements in maternal oral health literacy and children's oral health outcomes. Participants will be asked to: * Complete the REALD-30 questionnaire at baseline (pretest) and at the end of the program (posttest), with a one-month interval between assessments. * Accompany their children for DI-S and mGI examinations at baseline (pretest) and at the end of the program (posttest), with a one-month interval between assessments, conducted by a calibrated dentist. * Receive and study dental health education materials delivered progressively, one chapter per week, through either the application (intervention group) or a printed booklet (control group). Subsequent chapters will be unlocked in the following week. * Complete a daily checklist documenting their child's tooth-brushing activities every morning and evening throughout the study period. * For participants in the application group only: receive daily notifications/reminders and personalized educational messages (based on quiz scores and checklist compliance levels), and complete the Mobile App Usability Questionnaire (MAUQ) at the end of the program.
