RESUMEN
Abstract Objective: To investigate the effect of deploying a "First Aid Management of Dental Avulsion" poster in a primary school setting to improve teachers' knowledge. Material and Methods: The present study was conducted at public primary schools in central Jakarta, with 54 teachers meeting the inclusion criteria. The questionnaire contained 13 questions, divided into two sections. The first section consisted of questions about sex, age, education, length of service, field of education, and whether the teacher had received first aid management education before. The second section consisted of 7 questions about the teacher's knowledge regarding dental avulsion and its management. Baseline knowledge was defined by using a questionnaire and then teachers were shown the educational poster covering the first aid management of dental avulsion. Next, the teachers answered a post-education questionnaire, which included the same questions as the first questionnaire. A paired t-test or Wilcoxon's signed-rank test was used based on the distribution of data to determine the significance of the differences between before and after education. Results: The median score before reading the poster was 5, while the median score after reading it was 10. The difference was statistically significant. Conclusion: "First Aid Management of Dental Avulsion" poster could improve the knowledge of primary school teachers in Jakarta.
