Assessment of the impact of a multimedia-based dental education program on oral health knowledge and practices among high school students: A randomised controlled trial

Introduction: Oral health education is essential for adolescents, yet traditional methods face challenges in engaging this demographic. This study evaluates the effectiveness of a multimedia-based dental education program among high school students. This study was carried out to assess the impact of a comprehensive multimedia-based dental education program on oral health knowledge and practices among high school students. Methods: A total of 228 students were recruited and randomly assigned to experimental (n=114) and control (n=114) groups. The experimental group received a four-week multimedia program, while the control group followed the standard curriculum. Outcome measures included oral health knowledge scores, brushing frequency, flossing habits, dietary choices, and observational assessments. Statistical analysis employed descriptive statistics, paired t-tests, and analysis of covariance (ANCOVA). Results: The multimedia-based program led to a significant increase in oral health knowledge scores in the experimental group compared to the control group (Mean Change: 14.6, p < 0.001). Moreover, the experimental group demonstrated higher brushing frequency (p < 0.001), increased flossing habits (p < 0.001), and improved dietary choices (p < 0.05). Observational assessments showed higher adherence to oral hygiene practices in the experimental group (p < 0.001). Conclusion: The multimedia-based dental education program effectively improved oral health knowledge and practices among high school students. This approach holds promise for scalable and engaging oral health education strategies.
