“…Moreover, 3D files can sometimes lack an entertaining aspect and be too complex for students to manipulate [30], and therefore require the development of more user-friendly interphase. As the resources for the development of these educative tools are not always known, a dental faculty network, open-access publications or educational congresses could be relevant strategies to share tips and tools, such as 3D PDF files [7], free software to interact and paint on 3D files (Paint 3D, Microsoft, Redmond, EU) or Blender (Figure 6d,e), free web-based platforms (Metaciel, Université Clermont Auvergne, Clermont-Ferrand, France) [31], or open source codes of applications [9]. However, these practices are still recent, and additional studies will be necessary to deeply evaluate how these tools will help dental educators to teach and students to achieve their educational goals.…”
