Since 2001, an interdisciplinary project on multimedia education in medicine has been sponsored by the Federal Ministry of Education and Research at the Charité. One part of the project is on dentistry. In the light of the results of a survey of dental students, an Internet-based education management system was created using open-source back-end systems. It supports four didactic levels for editing documentation of patient treatments. Each level corresponds to the learning abilities of the students. The patient documentation is organized to simulate the working methods of a physician or dentist. The system was tested for the first time by students in the summer semester of 2003 and has been used since the winter semester of 2003 as part of the curriculum.
