Introduction Dentistry is the most profession affected by the globally COVID-19 pandemic. Future workplaces will be forced to follow a clinical protocol to avoid the emergence of new illnesses and spreading of the viruses. The patient’s oral secretions, contaminated materials, and dental unit surfaces may serve as possible sources of infection for the dentist, the assistant, and the patient during routine clinical practise. Saliva and blood droplets generated on surfaces, as well as aerosol inhalation from spinning machinery and ultrasound handpieces, offer a considerable danger to current and future occupants. To prevent infections, dental practitioners must use disinfectants and personal protective equipment (PPE). The rapid spread of Covid 19 has forced adjustments to preventative and restorative dental practises. In dentistry, COVID-19 preventive measures include telephone and clinical triage supported by a questionnaire on recent symptoms and movements, body temperature measurement, oral rinses with 1 percent hydrogen peroxide, and the use of appropriate PPEs (1).Dental Association of United States plan emergency recommendations incorporated in urgent dental care, which focuses on the management of conditions needing immediate attention to alleviate severe pain and/or infection risk. Urgent dental care focuses on disorders requiring minimally invasive treatment, including severe tooth pain due to pulpal inflammation, pericoronitis or third-molar discomfort, surgical post-operative osteitis, and dry socket dressing changes. Abscess or localized bacterial infection resulting in localized pain and edoema. Tooth fracture producing localized pain or soft tissue damage. Trauma to the teeth with avulsion/luxation (2).Telemedicine encourage delivery of health care services by using the communication technologies. The term of telemedicine is to improve health of patients in unaccessible areas .Teledentistry is a sub-group of telemedicine and is successfully used within the dental practice for teleconsultation, telediagnosis and delivery of oral care services . In Covid- 19 pandemic , teledentistry used an alternative method to deliver the continuation of dental health services .A systematic review concludedthat teledentistry was a valuable tool for oral screening similar to face-to-face consultations . Variable electronic devices were used to capture the intraoral soft and hard tissues such as smartphones, digital extraoral cameras, or intraoral cameras (3,4).Smartphones is a noval attractive way in telehealth services due to mobile connectivity, advancing digital photography technniques , storage and transfer data as well as low-cost, secure storage. The a smartphone camera could be used in dental photography which are useful for recording a baseline of oral health status preoperatively, to assess the diagnosis and preparing an appropriate treatment plan.Follow up evaluation by a speciality dentist from a distance(5).Mobile-health technology could used as adjunctive tool for emprovement careness of oral hygiene ,followup and increase awareness of health education .In covid 19 pandemic ,people are interested to have facilities of their health information in their smartphones. These apps have easy , simple performance and also provide simple information so further investigation are required in next steps(6,7).In oral health field, Dental caries is a common chronic disease of the childhood. some smartphones apps have used games to teach children many topics including carious tooth, healthy and carcinogenic diet. Dental caries in childhood can be associated withsevere pain and psychological problems, and may impose a high burden on the parents (8).Dental associations worldwide recommend the first dental visit and initiation of toothbrushing at 1 year of age. However, parents often neglect this visit. Dental health education via mobile apps can be a potential solution to enhance oral health knowledge of parents, particularly mothers, considering the popularity of mobile apps and their widespread use (9).Using social media (SM) is one of the most common people today’s activities. Websites which allow social interaction are considered SM platforms, allowing users to communicate, develop their creativity, increase their knowledge and getting health information. Health information through online may make the users feel more secure in expressing their primary concerns because their identities are masked and their privacy is guaranteed (10).Applications and services for telemedicine include email, two-way video, wireless tools, smart phones, and further communication technologies. Telemedicine involves group treatment, nurse contacts, teaching and training, televisits with community health experts, and medical image transfer. Telehealth, provides a larger range of distant healthcare services that are not often limited to the clinical context. These services, known as remote nonclinical services, consist of training, medical education, and administrative meetings. The two primary types of telemedicine are store-and-forward telemedicine and real-time telemedicine. Store-and-forward telemedicine does not need communication partners to concurrently transfer data. It is possible to gather, organise, and store data. Data are sent as often as possible to the desired destination for diagnosis or analysis. In addition to the patient’s information and medical history, images of skin lesions or electrocardiograms are sent to a physician in the linked area. Real-time telemedicine, like videoconferencing, needs simultaneous communication between the healthcare provider and the patient (11).Teledentistry’s limitations and constraints must be understood. The most prevalent technical concerns were Internet access and sound quality. All telemedicine mistakes may be categorised as technical, organizational, or severe. Universities and colleges must include telemedicine into their curricula and offer training for doctors. Telemedicine allows physicians to participate in continuing education programmes without leaving their existing roles. Teledentistry may thus be used to optimise and lower the cost of dental treatment. Additionally, teledentistry is often used during the anamnesis phase of patient evaluation(12).A significant barrier is the high cost of teledentistry for both governments and individuals. Teledentistry is a rapidly growing field with immense potential, but it is still in its infancy, and more emphasis must be placed on the distribution of funds and grants to conduct additional clinical research to provide more data and establish teledentistry’s role in the delivery of oral healthcare(13).Internet is the basis of modern teledentistry systems since it is current, rapid, and capable of delivering vast amounts of data. Recent teledentistry technology and remote consultation methods exist only on the Internet. Today, almost every dentist clinic is outfitted with intra-oral cameras, digital cameras, and Internet-connected computers, allowing for the rapid examination of teledental possibilities. Teledentistry is a novel part of patient care that is rapidly rising in popularity and significance. Practitioners who want to include teledentistry into their practises must educate themselves on the legal, technological, and ethical obstacles posed by this burgeoning field. Dentists are required to take initiative and adapt to the digital world. They must understand not only how the digital transformation of healthcare will affect their practises, but also how they and their patients may benefit from the expansion of teledentistry. Implementing teledentistry in professional dental education is a realistic and effective strategy for fostering teledental skills(14).Teledentistry is a rapidly growing field with immense potential, but it is still in its infancy, and more emphasis must be placed on the distribution of funds and grants to conduct additional clinical research to provide more data and establish teledentistry’s role in the delivery of oral healthcare.Inspite of benefit from teledentistry and the variety of applications, there are still restrictions on the use of information technology. Digital photographs may be useful for recognizing obvious issues, but they have their limitations. Teledentistry requires the use of high-quality pictures, which are unavailable at all remote clinics and facilities. A significant barrier is the high cost of teledentistry for both governments and individuals(15).
