A Just-in-Time Digital Learning Platform for Teacher Oral Health Training

This randomized controlled trial aims to evaluate the effectiveness and implementation of a Just-in-Time Digital Learning Platform designed to improve teachers' oral health literacy and support the delivery of oral health education in schools. Teachers play an important role in promoting healthy behaviors among children, but many have limited access to structured oral health training. Digital microlearning approaches may provide a scalable and cost-effective solution for strengthening teacher capacity in school-based oral health promotion.

Teachers assigned to the intervention group will receive access to a digital learning platform that delivers short, interactive, and evidence-based oral health training modules through mobile devices. The platform will provide educational content, reminders, quizzes, feedback, and progress monitoring. Teachers in the control group will receive standard information or routine training practices.

The study will assess changes in teachers' oral health literacy, knowledge, attitudes, and confidence in delivering oral health education. It will also evaluate implementation outcomes, including acceptability, feasibility, adoption, fidelity, reach, and engagement with the digital platform. In addition, the study will examine whether improvements in teacher training lead to better oral health knowledge, behaviors, and clinical oral health outcomes among students.
