The Influence of Dental Phantom Media on Tooth Brushing Knowledge Among Students with Moderate Intellectual Disabilities at SLB Rela Bhakti 1 Gamping

This study aims to determine the effect of dental phantom media on tooth brushing knowledge in students with moderate intellectual disabilities at SLB Rela Bhakti Gamping. The research was conducted at SLB Rela Bhakti Gamping from July to August in the 2024 academic year. A quantitative approach was employed, utilizing a pre-experimental one-group pretest-posttest design. The sampling method involved a census of the entire fourth-grade population at SLB Rela Bhakti Gamping. Data were collected through a pretest, an intervention (treatment), and a posttest. The data analysis employed a non-parametric statistical method, with descriptive analysis supplemented by hypothesis testing using the Wilcoxon signed-rank test at a significance level of α = 0.05. The hypothesis test revealed that the Asymp.Sig. (2-tailed) value was 0.042, which is less than the significance threshold of 0.05, thereby leading to the acceptance of the alternative hypothesis (H₁). This indicates a significant difference between the pretest and posttest scores regarding tooth brushing knowledge. Thus, it can be concluded that the use of dental phantom media has a significant positive impact on enhancing tooth brushing knowledge in students with moderate intellectual disabilities at SLB Rela Bhakti Gamping.
