It is crucial for parents to foster and enhance their children’s sense of oral healthcare behavior. It is necessary for parents to assist their children in developing habits such as tooth brushing, rinsing the mouth, and flossing. This observational study investigates the effects of an educational video before and after its use. The first step involved examining children to assess the plaque index and oral hygiene index. in the 2nd phase, pre-questionnaires and video links were sent to parents via WhatsApp for their education. A subsequent contact was made to verify that the child had been shown the entire video. Three weeks later, the third step was executed. It featured an additional measurement of the plaque and a simplified oral hygiene index to facilitate comparison between the pre- and post-examinations. Ultimately, the parents were requested to complete the post-survey. The findings illustrate the difference in average values for before and after the video demonstration, suggesting that while the difference in calculus is not statistically significant, the difference in plaque index is. The carrying out of educational intervention results in a considerable enhancement of children’s oral health.
