1. Introduction

Teledentistry is a ray of hope that improves patient accessibility and comfort whilst also bridging regional divides. Teledentistry facilitates real-time contact between dental professionals and patients resulting in timely interventions and personalised care. With advancements in technology, telehealth services have strengthened patient accessibility and comfort whilst also bridging regional divides [1, 2]. It includes a broad range of services that may be provided virtually, such as remote consultation, evaluation of oral health lesions which does not require radiograph, primary diagnosis based on existing health records, treatment planning, and follow-up visits. All of these can be done without the requirement for in-person presence. This chapter aims to highlight the significant influence of teledentistry in addressing inequities in oral health by legislative progress, patient-centric care, collaborative approach, and raised consciousness in order to bridge the gap in oral health access. By exploring the history, applications, and challenges involved in the integration of digital tools and platforms, this chapter seeks to demonstrate the tremendous impact it has on mitigating disparities in oral health [3, 4, 5].

2. Teledentistry: a solution for the underserved population

Teledentistry fills critical gaps in oral healthcare access for marginalised groups, especially the elderly in nursing homes and people with special needs (Figure 1). Traditional dental appointments are sometimes hampered for these disadvantaged populations by obstacles like restricted mobility, remote location, and inadequate financial resources. By removing these obstacles and providing remote consultations, diagnostics, and customised care plans, teledentistry emerges as a lifeline, which contributes to the patients’ overall well-being [6, 7, 8].

2.1 Unique challenges facing impoverished populations in dental health

Oral health is a complex issue for underserved groups, made worse by things like financial hardships or restricted access to care owing to remote locations (Figure 2). Oral health problems are made worse for the elderly living in nursing homes and for those with special needs who frequently struggle with limited mobility, communication difficulties, and complicated medical conditions. These difficulties are further exacerbated by a lack of knowledge and instruction, which raises the prevalence of untreated oral issues. To close the gap and guarantee equitable oral healthcare delivery, these disadvantaged groups must overcome significant barriers to preventative and restorative dental services. One such alternative is teledentistry [9].

Teledentistry serves as an accessible platform which changes the way dental care is delivered for everyone, irrespective of geography or physical constraints aiming to achieve equitable oral health [10, 11].

3. Advancements in teledentistry technology

Remote consultations are made possible via teledentistry, which facilitates easy contact between dental specialists and patients (Table 1). Dental professionals do virtual examinations, address issues, and provide preliminary diagnosis via video conferencing and secure platforms. This strategy makes it easier for underprivileged populations—particularly those with restricted mobility or geographic restrictions—to quickly obtain professional counsel [12]. It lowers obstacles to care and improves early interventions for oral health concerns by enabling patients to get advice without needing to make in-person visits [13, 14].

High-resolution dental pictures are captured and sent for evaluation and diagnosis in teledentistry using digital imaging. With the use of these technologies, dental diseases may be evaluated remotely, which helps with treatment planning and progress tracking. With the use of telemonitoring equipment, continuous treatment may be provided remotely in real time by assessing indications of oral health. This innovation is especially helpful for vulnerable populations since it ensures fast treatment plan modifications and constant monitoring without requiring numerous in-person visits [15, 16, 17].

Modern technologies like 3D printing, intraoral scanners, and artificial intelligence are introduced by the development of teledentistry. These developments improve tailored care, accuracy of diagnosis, and precision of therapy [18]. Whilst 3D printing makes it easier to create customised dental items remotely, AI systems assist in the analysis of photographs for the diagnosis of disease. The precision of treatment planning and remote consultations has been revolutionised by intraoral scanners, which allow for exact digital impressions [19]. A new age in teledentistry is being ushered in by the combination of these cutting-edge technologies, one that promises more capabilities and better results in the provision of remote oral healthcare [20, 21].

4. Practical implications of teledentistry

When taken as a whole, these case studies highlight how teledentistry improves oral health results (Figure 3). They show a significant decline in untreated dental problems, a reduction in the incidence of oral illnesses, and an improvement in participants’ general oral hygiene. Additionally, they show improved patient satisfaction, emphasising the practicality and simplicity of the use of remote dental services. The use of teledentistry not only helps with urgent dental requirements, but also promotes preventative treatment, which improves oral health and general well-being [22, 23]. Initiatives including teledentistry for people with special needs and in nursing homes have shown to be very effective in improving oral healthcare results and accessibility [24].

4.1 Customising teledentistry for elderly patients

The cognitive, physical, and technical constraints of older patients must be taken into account whilst designing teledentistry services to meet their needs. User-friendly platforms, aided technologies, and simplified interfaces address possible issues with dexterity or inexperience with digital instruments. During remote consultations, older patients can feel empowered and at ease by emphasising clear communication, patience, and support throughout the virtual treatment process. This encourages patients to take an active role in their oral healthcare [23, 24, 25].

4.2 Adapting services for people with special needs

Teledentistry needs to address the specific needs of those who are disabled. This entails using staff members who have been educated to handle a variety of demands, as well as adaptable technology and augmentative communication tools. During virtual consultations, tailored techniques take into account deficits related to sensory processing, cognition, or physical functioning, promoting pleasant and productive encounters. Incorporating diverse communication styles and offering substitute means of exchanging information guarantees inclusiveness and promotes a favourable encounter for patients with exceptional requirements [26].

4.3 Ensuring accessibility and inclusivity

A key component of patient-centred teledentistry is accessibility. Incorporating functionality like text-to-speech, captioning, and language translation services guarantees inclusion for a variety of language- and hearing-impaired groups. Moreover, accessibility is improved by guaranteeing compatibility with assistive technology. Inclusivity is further promoted by addressing socioeconomic differences by providing low-bandwidth alternatives or collaborating with community centres for technological access. By incorporating universal design principles into the development of teledentistry platforms, usability for patients from a range of demographic backgrounds is ensured, promoting fair access to superior oral healthcare services [27, 28, 29].

4.4 Examples of teledentistry programmes in foreign countries

Case studies highlight the transforming influence of teledentistry programmes conducted globally (Table 2). These programmes give senior citizens full dental treatment by utilising computerised diagnostics and remote consultations. These programmes address obstacles such as restricted mobility and transportation issues by forming relationships between dental practitioners and care institutions. By providing dental services to people directly, these programmes help to improve oral health outcomes for this vulnerable population by facilitating prompt treatments, preventative care, and early interventions specifically during the COVID pandemic [27, 28].

Regulatory obstacles for teledentistry include those related to licensure, privacy, and telehealth rules, which differ by location. The scalability of services is impacted by the frequent complexity of interstate practice caused by compliance with disparate state requirements [30].

5.2 Technological limitations

It is difficult to provide high-quality technological infrastructure in underserved or distant locations when there is a lack of sufficient digital resources or reliable internet access. Its application is further constrained by the lack of interoperability with current dental software and the availability of advanced diagnostic equipment, requiring significant investments in technological improvements [21].

5.3 Patient and provider acceptance

Both patients and dental professionals are resistant to the use of teledentistry. Patients who prefer in-person visits to online treatment may display scepticism owing to worries over the quality of virtual care. At the same time, dentists may be reluctant to accept teledentistry because they believe that it will be difficult to do thorough examinations or provide practical treatments from a distance [31].

5.4 Insurance and reimbursement issues

The lack of uniformity in compensation schemes and coverage gaps for virtual consultations makes teledentistry practices financially unviable. Encouraging the widespread adoption and sustainability of teledentistry projects requires addressing these payment gaps and pushing for fair compensation for remote dental treatments [31, 32].

It is essential to promote joint ventures between dental practitioners, medical facilities, and technological specialists. Working with legislators to develop uniform standards for privacy laws, telehealth reimbursement, and licencing promotes uniformity and clarity between jurisdictions. In addition, resolving legal obstacles, advancing telemedicine-friendly legislation, and compensation for services are also important areas of advocacy work. Collaboration allows for the sharing of infrastructure, knowledge, and resources, which promotes creative thinking. Opportunities for synergy are revealed through collaboration amongst stakeholders, including lawmakers, healthcare institutions, dentistry experts, and tech developers [34].

7.2 Community engagement and outreach

Engagement with the community and outreach programmes are essential to promoting acceptability and use of teledentistry. Outreach programmes may be more effectively tailored to cater to the requirements, languages, and cultural sensitivities of a varied community. Forming alliances with neighbourhood groups bolsters outreach initiatives and encourages participation and ownership in the teledentistry-based promotion of oral health [34, 35].

7.3 Training and education for dental professionals

In-depth training courses and ongoing education are essential for giving dental practitioners the skills they need to implement teledentistry. Improvements in machine learning algorithms, remote imaging methods, and artificial intelligence hold the potential to improve precision [35].

8. Conclusion

With all the technical advancements in teledentistry, dentists may ultimately connect to online dental health clinics, ushering in a completely new age in dentistry. Traditional dental appointments are sometimes hampered for these disadvantaged populations by obstacles like restricted mobility, remote location, and inadequate financial resources. However, there are a number of challenges associated with legal frameworks including licensure, remuneration, malpractice liability, patient privacy, jurisdiction, electronic commerce, and fiscal and taxation guidelines, which necessitate further improvements in order to ensure seamless implementation. Validating the many facets of teledentistry applications will require larger-scale research with more participants. In order to create a future where everyone, regardless of their circumstances, has access to oral health, teledentistry must be progressively integrated into the healthcare system. On a broader level, Teledentistry is more than just a technology; it is a tool that empowers communities.
