This educational video discusses, with unprecedented 3D modelling, the development of the teeth. It was designed to facilitate the understanding of the odontogenesis, by giving a simple representation, in time and in space, of the different stages leading to the development of the crown. This video is offered under the aegis of the French National College of Teachers in Biological Dental Sciences (CNESBO). Produced by the team from the Production and Digital Innovation Department of Health at the University of Nantes, it was selected and funded by the UNF3S (Francophone Digital University of Health, Sciences and Sports). This university offers teachers and French speaking students a free access to digital educational resources.
