Summary

The goal of this intervention study was to evaluate the effectiveness of a two-month interactive school-based oral health education program in reducing periodontal disease and improving oral health behaviors among 15-year-old schoolchildren in Nablus, Palestine.

The study was guided by the following hypotheses:

* The interactive education program would lead to a significant reduction in Community Periodontal Index for Treatment Needs (CPITN) and Simplified Oral Hygiene Index (S-OHI) scores.
* The program would result in significant improvements in oral hygiene practices, dietary habits, and smoking behaviors compared to standard oral health education.

Researchers compared students who received six interactive oral health sessions over two months to those who received a single standard oral health lecture, to determine whether the intervention group experienced greater improvements in periodontal status and self-reported health behaviors.

Participants:

* Completed self-administered questionnaire assessing oral hygiene practices, dietary habits, and smoking behaviors
* Underwent clinical periodontal examinations using CPITN and S-OHI indices
* Participated in oral health education sessions (intervention group only)

Interventions

BEHAVIORAL

"Interactive Oral Health Education Program"

The interactive program in this study is distinguished by its multi-modal, hands-on approach and its sustained, bi-weekly delivery over two months, whereas most other school-based interventions rely on a single lecture or short-term animation. Specifically, our program: Combines interactive lectures with live demonstrations (brushing/flossing on models), group discussions, and educational puzzles to reinforce learning through active participation rather than passive listening. Uses anatomical tooth-and-gum replicas alongside PowerPoint slides and photographs to bridge theory and practice within each 30-45-minute session. Addresses periodontal risk factors (e.g., smoking, diet) in dedicated sessions, integrating behavioural change techniques (e.g., problem-solving brainstorming, personalized feedback) rather than focusing solely on plaque removal. Is delivered in six sessions (one every 10 days) to maximize retention and allow for iterative skill practice, unlike brief "brush-along"
