Teledentistry is the use of information technology and telecommunications for dental care, consultation, education, and public awareness (compare telehealth and telemedicine). History In 1994, the Department of Defense introduced the Total Dental Access Program (TDA) for the Army. The goals of TDA were to increase soldier's access to care and reduce associated costs. At the time, they used what was called the plain-old-telephone-system (POTS). In the early nineteen nineties, videoconferencing, e-mail, fax, and telephone calls were used but more recently, video conferencing and high-quality image transfer have become easily accessible. These, and the considerable improvements in digital camera technology, have provided radical new opportunities. Nearly a third of all Americans don't visit a dentist regularly enough, according to the Gallup-Healthways Well-Being Index. There are many reasons for this, most notably affordability, access and fear. Several teledental companies operate in the United States. Direct-to-consumer orthodontics companies like SmileDirectClub also utilize teledentistry, but have drawn criticism regarding proper supervision of care. Due to the COVID-19 pandemic, dental practices were ordered to be shutdown to help curb the spread of the coronavirus. As a means of providing a method by which dentists could still communicate with their patients during the shutdown, teledentistry became adopted across the world. In the USA, several laws had been enacted to curb the rise of direct-to-consumer orthodontics which also invalidated the use of teledentistry by duly licensed dentists. These laws were quickly rescinded to address the pandemic and hence teledentistry is now widely used by dentists in the USA. Methods and Modalities Live Video (Synchronous): Live two-way video between a patient and provider using audiovisual telecommunications technology. Live video is often used to triage patients to the appropriate level of care or for specialty consultations. The American Dental Association has designated the code D9995 for this type of teledentistry. Store-and-forward (Asynchronous): Transmission of recorded health information (for example, radiographs or digital impressions taken by an appropriately licensed provider) through a secure electronic communications system to a practitioner, who uses the information to evaluate or diagnose the patient's condition outside at a later time. The American Dental Association has designated the code D9996 for this type of teledentistry. Remote Patient Monitoring: Health data collection from an individual in one location (usually outside of a conventional clinical setting), which is transmitted to a provider in a different location for use in care and related support. mHealth: Health promotion and education
