Data analysis used was non-parametric test using Mann Whitney and Wilcoxon Sign Rank Test. Results: The mean OHIS value in the pre-test group was 1.64 and decreased to 1.06 in the post-test. There was a difference of the OHIS before and after giving tooth brushing counselling using PowerPoint media 0.007 (p < 0.05). The mean OHIS value in the pre-test group was 2.65 and decreased to 1.33 in the post-test group. There was a significant difference in the score between the pre-test and post-test group.
