Abstract
INTRODUCTION: Video-based learning has emerged as a powerful tool to overcome the well-documented limitations of traditional lectures. Hence, the aim of this study was to investigate the impact of the implementation of a video animation on academic performance and student's opinion. METHODS: A video animation on biological mechanisms behind the link between periodontitis and its treatment with atherosclerosis and diabetes was projected in addition to the traditional lecture to 46 4th-year undergraduate dental students enrolled in the 2024-2025 academic course at the University of Santiago de Compostela. A multiple-choice test including eight questions was delivered to assess student's knowledge after the lesson. Also, student´s perception on the use of this video animation was evaluated by the User Experience Questionnaire. RESULTS: The video animation tested in this study shows excellent results in terms of attractiveness, perspicuity, efficiency and dependability. Good results are observed for stimulation and novelty. Almost 3/4 of undergraduate dental students obtained very good or outstanding marks in the test. CONCLUSIONS: The use of a video animation to explain biological mechanisms underlying the link between periodontitis and systemic diseases appears to be a helpful tool for undergraduate dental students.
