Recently, the World Wide Web has emerged as a platform for computer-based oral health records. Web-based patient records can make teledentistry an instant reality. Because an increasing number of dental care providers can access Web pages, traditional barriers to exchanging information are dropping. Web-based records also make cumulative, longitudinal patient records possible. Sophisticated security mechanisms can ensure the integrity and confidentiality of patient information. Because Web-based systems are simpler to install and configure, the cost of operating them may be reduced. However, their development Is complex, difficult, and expensive because the Web was not developed as a programming environment.

In addition, several policy questions, such as storage of and access to computer-based patient records, have to be answered.
