Introduction. The imperative of global society is a change. The most effective way that modern man is “in step“ with daily changes is the application of information and communication technologies. Expansion and development of information and telecommunication technologies rapidly found their application in the health care system by improving medical practice itself. Medical informatics with its specific subbranch – dental informatics is engaged in the development, implementation and evaluation of information technologies in medicine and dentistry, ie. solving problems related to information and communication in health care. The Internet is the largest global network today and is increasingly used in medicine and dentistry. Using the Internet and other telecommunication methods allows us to easily keep pace with the continuous expansion of knowledge base. The entire information technology has been recognized as an integral part of the health care and an important element of good clinical practice, resulting in the emergence of telemedicine, teledentistry and telepharmacology. Telemedicine with the use of modern communication systems enables the transfer of medical data, which can provide medical services regardless of physical location of doctors and patients.
Conclusion. Teledentistry is the combination of telecommunication and dentistry, it involves the exchange of clinical information and images over long distances for specialist dental consultation, diagnosis and treatment planning. Pillars of modern teledentistry are the application of the Internet and the rapid flow of data.
