Background: The epidemiology of head and neck cancers has changed dramatically, with Human Papillomavirus (HPV) surpassing tobacco as the main etiologic agent of oropharyngeal squamous cell carcinoma (OPSCC) in many developed and developing regions. Despite the increasing prevalence of HPV in Iran, dental professionals still show limited diagnostic preparedness and persistent stigma. This study evaluated the effect of a structured multimedia educational intervention on dental interns’ knowledge and attitudes regarding Human Papillomavirus (HPV) transmission, pathology, and vaccination.
Methods: This quasi-experimental pretest/posttest study was conducted in 2025 among 35 dental interns at Shiraz University of Medical Sciences. Participants were selected by simple random sampling. Knowledge and attitudes were assessed using a validated questionnaire adapted from Kazerani et al. (CVI > 0.90) at baseline and one week after an audio-visual educational intervention. The intervention focused on viral pathogenesis, early lesion recognition, and patient counseling. Data were analyzed using paired t-tests, independent t-tests, and linear regression (P < 0.05).
Findings: Knowledge scores increased significantly from 20.23 ± 6.41 to 31.17 ± 2.75 after the intervention (P < 0.001; Cohen’s d = 1.7). Attitude scores also improved from 15.34 ± 2.21 to 18.31 ± 0.76 (P < 0.001), indicating reduced stigma and a more professional outlook. Baseline knowledge was a significant negative predictor of learning gain (β = -0.41), suggesting that the intervention was especially beneficial for students with lower initial knowledge. No significant gender differences were observed.
Conclusion: A targeted, multimedia-based educational module is highly effective in reducing theoretical knowledge gaps and fostering positive professional attitudes among dental trainees. The findings support the integration of such standardized multimedia interventions into the national dental education curriculum to enhance the competence of future clinicians in the early detection and prevention of HPV-related malignancies.
