The subjects of this study were 15 intervention groups with the application of the TR'S Dental Pop-up educational model and 15 control groups with the application of the 3D boo pop-up educational model without audio. Sampling using the Lemeshow formula. Data were tested using the Paired test and independent sample test. Results: TR'S Dental Pop-up is appropriate as a learning media about brushing teeth. The implementation of this media is effective in increasing teacher knowledge (Δ) intervention 2.67 control 1.66, teacher attitude (Δ) intervention 3 control 1.67, teacher action (Δ) intervention 4 control 3, children's actions (Δ) intervention 5.8 control 3.8, intervention debris (Δ) 0.97 control 0.86.
