Background paired and independent t-tests) was performed with significance set at p < 0.05. Results: At follow-up, the intervention group showed significant reductions in CPITN (from 10.99 ± 2.77 to 10.00 ± 2.64; p < 0.001) and S-OHI (from 12.90 ± 3.10 to 10.89 ± 2.78; p < 0.001). Significant improvements were also observed in oral hygiene practices, dietary habits, and smoking behaviour scores (all p < 0.001). No significant changes occurred in the control group. Conclusions: The interactive, school-based oral health education program effectively improved periodontal health, oral hygiene status, and related behaviours among adolescents.
