Aim: This randomized controlled parallel trial investigates the effect of 3D animation on the increase and recall of knowledge on periodontitis by patients with periodontitis. The effects of a 3D animation (3D animation group) were compared to narration and drawing (control group) for periodontal patient education.
Material and methods: 68 periodontitis patients were stratified according to educational level and then randomly allocated to control or 3D animation groups. All patients received: 1) a pre-test (baseline knowledge), 2) a patient education video (3D animation or control video) 3) a post-test (knowledge immediately after looking at the video) and 4) a follow-up test (knowledge recall after two weeks). Each test contained ten multiple-choice questions.
Results: There was no significant difference in baseline knowledge. Patients receiving the 3D animations had significantly higher scores for both the post-test and the follow-up test, when compared to patients receiving sketch animations.
Conclusion: 3D animations are more effective than real-time drawings for periodontal patient education in terms of knowledge recall. 3D animations are a powerful tool for assisting in the information process.
