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.

Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
