| Summary: | Abstract Introduction The challenge of teaching the subject of tooth development lies in the explanation of a complicated three-dimensional process occurring within a small, confined space over a period of time. Further, there are few illustrations available to dental educators and most of them are two-dimensional. Histological sections and computer-generated diagrams cannot properly capture events such as how each stage in development comes about and then seamlessly transition to the next stage, or how embryologic events can explain morphologic features in an erupted tooth. The goal of this project was to educate dental students about the initial development of the tooth as a bud and the architecture and development of enamel utilizing a series of three-dimensional models and animations that successfully describe these processes Methods There are no special requirements to run the animation other than Quick Time software and working audio output and speakers. The presenter may elect to do without the narration and explain the animation him/herself. It is recommended that the presenter run the animation as a stand-alone file rather than trying to embed into a PowerPoint presentation, given the large size of the animation file (269 MB). The animation runs for 2 minutes and 24 seconds. Results The animation has been distributed to faculty at the College of Dental Medicine for initial peer review. Faculty comments included “I just watched the tooth development animation. It is simply outstanding, really enjoyed it very much. It is simple, yet sophisticated and highlighted the main embryologic events of odontogenesis” and “I just took the time to watch your illustration and it is amazing! I thought it described a very complex process.” Discussion There is an untapped field of dental processes that could benefit from three-dimensional animations. The animation itself could be expanded upon with further research on tooth development. A few subjects that could be added to the series include the formation and architecture of enamel and dentin, the development and structure of the periodontal ligaments, root formation, and the eruption and shedding of teeth. Since detailed knowledge of development of the teeth is of paramount importance to the practice of most dental subspecialties, there is a large audience in need of clear, accurate, and timely information on this subject.
