RESUMO
BACKGROUND: Incorporating video as a tool for education offers a multitude of advantages. However, it is unknown what is the best educational tool to use for increasing public awareness, consequently reducing fear about root canal treatment. For this reason, this study aimed to compare the effectiveness of educational animation and leaflets as delivery methods for providing information on root canal treatment to patients and to assess their ability to retain the information. METHODS: One hundred fifty adult volunteers were recruited via social media and Umm Al-Qura University Dental Hospital to participate in this randomized control trial study. The volunteers were divided into the study group (SG) and the control group (CG). The SG was provided with information through animations created by the research team, while the CG received the same information through a leaflet. Pre-intervention (T1), immediate post-intervention (T2), and one-month post-intervention (T3) validated questionnaires were completed by the participants to assess the changes in their knowledge. To evaluate the impact of the information delivery method, the knowledge scores of T2 and T3 were compared to T1 within each group using Paired T-tests. Additionally, the study compared the knowledge scores of the two groups using unpaired T-tests. The significance level was set at a P-value of less than 0.05. RESULTS: A significant improvement in endodontic therapy knowledge among the participants in both groups (T1 compared to T2 in the same group) was noted (P < 0.050). However, when comparing T2 between groups, no significant difference was found in delivering the information and improving the knowledge (P = 0.080). Still, the mean differences between T1 and T2, as well as T1 and T3, were greater (P < 0.050) in the SG than in the CG. Furthermore, the total knowledge score in the SG at T3 was significantly higher than the CG. CONCLUSION: Both educational animation and leaflets are practical tools to increase patients' awareness about root canal treatment. However, educational videos are more effective than leaflets in delivering and retaining information about root canal treatment. TRIAL REGISTRATION: This study was retrospectively registered as a randomized control trial at the ISRCTN registry with the document number ISRCTN18413241, 15/05/2023.
