Dentistry is a field in biomedicine which usually requires presence of a therapist for diagnosis as well as for therapy. Therefore it seems that there is no solid base for application of IT for distance diagnosis and therapy procedures. Modern dental units, which are currently present on a market include intraoral cameras, which are capable of producing high quality intraoral images and real time video signal capture. Currently these cameras are being us ed to provide better understanding of dental procedures and their results. There are many projects which utilize such technology in many specialty branches in dentistry. Protocols developed for specialists of orthodontics which can provide a checkup appointments for a patients undergoing orthodontic therapy are being developed at Institute of Learning and Research Technology, University of Bristol, UK. and University of California, School of Dentistry, USA.; for specialists of periodontology Web-based intervention system for periodontal health is being developed at Department of Preventive Dentistry, Graduate School of Dentistry, Osaka University, Suita, Japan; in field of preventive and restorative dentistry there are continuous efforts at Department of Pediatric Dentistry, University of Texas-Houston Health Science Center, Huston, USA.
