Abstract

Introduction: The Baseline Health Research on 2018 showed the 15-24 year old adolescents’ knowledge of an appropriate way to brush the teeth was 3.3% which was in the low category. The low knowledge of dental health becomes the main cause of dental caries. The great way to improve dental health knowledge is the health education via Instagram Podcast. Methods: An analitical observational study was performed along with one-group pre-test post-test conducted on August 2021. The population was 390 students of Kalibaru Vocational High School, Banyuwangi Regency. The sample was 85 students taken by simple random sampling. The variable was dental and oral health knowledge measured by the questionnaire. The questionnaire was distributed before and after the health education. The data were analysed by Wilcoxon Signed Rank Test to recognise the difference between the knowledge before and after the health education. Results: The 53 students (62.4%) were female and the rest of them was male. The 44 students (51.8%) were 16 years old and the rest of them was 15, 17, 18, and 19 years old. The average score of pre-test was 68.47 while post-test was 85.18. The average score of post-test increased. The result of Wilcoxon Signed Rank Test showed p value=0,00 less than α(0,05) which meant there was a difference between pre-test and post-test score. Conclusion: There was a difference between the knowledge of dental and oral health before and after the health education via Instagram Podcast.
