The sample was divided into 2 groups: 15 students in the intervention group and 15 students in the control group. Sampling using the Lemeshow formula. The data were tested using the Interclass Correlation Coefficient, Paired t-test, and Independent t-test. Result of Research: Smart Toothbrush is appropriate as an educational medium about brushing teeth (p=0.011). The implementation of this media was effective in increasing knowledge (p=0.015), attitude (p=0.009), and brushing skills of parents of blind students (p=0.021) compared to the control group.
