One of the critical factors in maintaining good oral health is proper oral hygiene practices. Intervention given in the formative years of the child will be there for a lifetime. The oral health status of the children may be improved if health education in schools is conducted in a comprehensive and interesting manner. The aim of the study is to assess the effectiveness of comic books vs comic videos in refining tooth brushing habits and plaque scores among primary school children. 90 primary school students aged 7-9 years from three different primary schools will be included in this study. Schools will be randomly assigned as a comic book group, a comic video group, and a control group which will be provided with the traditional method of teaching tooth brushing habits. All the 3 groups will be provided with toothbrushes and toothpaste. Baseline plaque scores will be recorded and after 6 weeks post-intervention plaque scores will be recorded along with tooth brushing habits to see the effectiveness of the two interventions. Collected data will be subjected to descriptive statistics and normality tests will be performed based on the type of data distribution appropriate statistical tests will be applied.
