Neben dem stetig wachsenden medizinischen Lehraufkommen müssen auch die für die Ausübung des zahnärztlichen Berufes notwendigen feinkoordinativen Fähigkeiten gepaart mit dem Visualisierungs- und Vorstellungsvermögen der zu präparierenden Kavität, in einem engen Zeitrahmen vermittelt werden. Dies wird man inZukunft nur durch die Anwendung effektiverer Ausbildungsmethoden erreichen - zum Beispiel durch den Einsatz computergestützter Dentalsimulatoren, welche den visuellen, auditiven und praktischen Lernkanal simultan bedienen. Im Gegensatz zu den konventionellen Phantomkursköpfen hat der computergestützte Dentalsimulator DentSim der Firma DenX, Israel folgende Vorteile:
- die theoretische Wissensvermittlung findet in einem multimedialen Lernumfeld mit einem hohen Grad an Audio- Visualität, Interaktivität und Komplexität statt,
- problemorientiertes Lernen durch klinisch bezogenes Arbeiten,
- selbstständiges Arbeiten durch digitale Tutorfunktion,
- Transfer des zweidimensionalen Wissens ins dreidimensionale räumliche Arbeiten,
- Transfer der dreidimensionalen Präparation in einfacher zu internalisierbare zweidimensionale Fehleranalyse,
- die elektronische Aufzeichnung aller Präparationsübungen für Fehler- und Effektivitätsanalyse des Präparationsprozesses.
Über die studentische Ausbildung hinaus können die computergestützten Simulatoren auch zur Evaluierung der Effektivität bzw. Qualitätssicherung verschiedener Ausbildungsmethoden im Sinne einer evidenzbasierten zahnmedizinischen Aus- und Weiterbildung eingesetzt werden.

Virtual reality-based preclinical simulation learning is a new teaching modality with significant potential. The University of Tennessee Health Science Center, College of Dentistry has completed its first year of student experience using 40 DentSim simulators, in conjunction with an 80-unit traditional simulation laboratory. This article describes this experience and relates both the positive and negative aspects as they impacted on the students, staff, and school. The purpose of the article is to relay information pertinent to this new educational modality to other educational institutes interested in pursuing virtual reality dental simulation. The results of the first-year experience were encouraging, although certain areas proved problematic and frustrating for both students and staff.

A glance at the history of distance learning shows that there is a long tradition of using contemporary technical resources for learning and teaching purposes. For some, the holy grail of distance learning is the concept of the industrialization (mass production) of teaching and learning. Although reality has time and again caught up with technological promise, the scope for using new information and communication technologies in teaching has frequently been disregarded. In the future, learning will entail handling organized knowledge resources in demandspecific, organized communities formed for finding solutions to distinct problems and generating new knowledge about learning processes within the problem solving process. The development of the potential of "e-learning" (and actually, it bears contemplating whether this term puts too much emphasis on conventional learning organized in temporally-limited courses or similar, to the detriment of intelligent management of knowledge in its own working context) will depend upon the extent to which organizations succeed in promoting the development of a learning and working culture, for example, by incentive systems, team promotion, and free access to knowledge resources. The Masters degree in Organization Studies is presented against this background as an example of teaching using a combination of resources, leading to undreamed of learning success.

This article describes the development and application of new didactic methods for use in computer-assisted teaching and learning systems for training doctors and dentists. Taking theMeducase project as an example, didactic models and their technological implementation are explained, together with the limitations of imparting knowledge with the "new media". In addition, legal concepts for a progressive, pragmatic, and innovative distribution of knowledge to undergraduate students are presented. In conclusion, potential and visions for the wide use of electronic learning in the German and European universities in the future are discussed.
Self-directed learning (SDL) is a key component in both undergraduate education and lifelong learning for medical practitioners. E-learning can already be used to promote SDL at undergraduate level. The Meducase project uses self-directed, constructive, case- and problem-oriented learning within a learning platform for medical and dental students. In the long run, e-learning programs can only be successful in education if there is consistent analysis and implementation of valueadded factors and the development and use of media-didactic concepts matched to electronic learning. The use of innovative forms of licensing - open source licenses for software and similar licenses for content - facilitates continuous, free access to these programs for all students and teachers. These legal concepts offer the possibility of innovative knowledge distribution, quality assurance and standardization across specializations, university departments, and possibly even national borders.

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.

Öffentliche wissenschaftliche Datenbanken sind im Internet für die globale Recherche von zitierfähigen Publikationen ubiquitär zugänglich. Wissenschaftliche Mitarbeiter erbringen aber auch wesentliche Leistungen bei der Erstellung von nicht-zitierbaren Inhalten, wie Posterpräsentationen auf Kongressen, Fortbildungsartikeln oder Lehrinhalten für Aus-, Fortund Weiterbildung. Intention der Datenbankentwicklung war die systematische Erfassung aller Publikationen des Zentrums für ZMK und deren Bereitstellung im Inter- und Intranet. Während in den geschützten Intranetbereichen die vollständigen Listen aller zitierbaren und nicht zitierbaren Inhalte zu finden sind, ist für jede Fachdisziplin des Zentrums frei konfigurierbar, welche Publikationstypen ab welchem Jahresdatum in den frei zugänglichen Internetbereichen abrufbar sind.

Learning the widely differing forms of tooth preparation, especially in restorative dentistry, places high demands on both trainees and instructors with regard to precision, reproducibility, assessment, evaluation and three-dimensional conceptualization. In the past, evaluation of such preparations has been against subjective parameters and their interpretation by the assessor (usually the instructor). The use of CAD systems in teaching seminars and courses allows an objective assessment of tooth preparations and offers the trainee the possibility of measuring him/herself against a standard, of detecting errors, and of achieving perfection in the required tasks. The PREPassistant system described in this article is one such CAD-assisted learning system. It is recommended both for students in dental schools and for the continuing education of established dentists. Its strengths are that it produces a design for a tooth preparation, enables exact comparison with an ideal preparation, detects errors, and promotes improvements and perfection.
