What this trial studies

The trial investigates an intervention grounded in the Expanded Health Belief Model to promote oral health behaviors in college students. Participants are undergraduate students 18-25 years old who will receive the EHBM-based program, with outcomes focused on adherence to brushing, flossing, and regular dental check-ups. The study builds on prior work linking health beliefs to preventive dental behaviors and uses a real-world educational approach to test behavior change. Eligibility excludes those with orthodontic appliances, recent major dental treatment, pregnancy, or involvement in other oral-health trials. The lead sponsor is the University of Baghdad with sites at Southern Technical University in Basra.

Why it matters

Potential benefit: If successful, participants could develop lasting, improved oral hygiene habits and more consistent dental care.

How similar studies have gone: Prior educational interventions based on the Health Belief Model have shown improvements in brushing, flossing, and dental visit frequency in various populations.
