Representative survey of dental students about the present state of education, PC equipment and configuration requirements for a net-based dental education system.

A representative survey of 130 dental students revealed that the necessary conditions for using net-based education systems seem to exist, as 99% of all students have access to a PC, of which most (78%) own one. As most of them use the PC at least several times a week, they seem to be adequately skilled to deal with hard- and software. Internet and emailing are the most commonly used features of the PC after text documentation, therefore it can be inferred that almost all computers have Internet access.
