Introduction

According to the 2022 Global Oral Health Status Report by the World Health Organization (WHO), almost half of the world's population suffers from a type of oral disease. These are alarming statistics, given that oral diseases don't just affect the mouth; but can also have an impact on overall health. Research has shown that oral diseases are associated with severe serious health issues like diabetes, heart disease, depression, inflammatory bowel disease (IBS), and even certain cancers.¹ Even though many oral diseases are preventable, people in rural and remote areas often struggle to get dental care due to factors, such as geographical isolation and limited transportation.² As a result, people in these communities usually suffer from poor oral health with less awareness of oral health practices than in urban areas.³ Without guidance from dental professionals, these communities will continue to lack the knowledge and tools necessary to maintain good oral health. Ensuring that everyone has access to dental care regardless of location, regardless of their location, has access to dental care is essential. One effective solution is teledentistry, which enables patients to consult with dental professionals remotely, eliminating the need for physical visits to the dentist's office. In this article, we will explore teledentistry, its benefits, and how it enhances access to dental care, particularly for individuals in remote areas.  

What is teledentistry?

The term ‘Teledentistry’ was first coined in 1997 by Cook, who described it as using video conferencing for remote diagnosis and treatment advice.⁴ Teledentistry allows dentists to interact with patients virtually through video calls, text messages, online platforms, and phone calls for dental care purposes, like consultation, diagnosis, treatment planning, and dental education.⁵ 

How does teledentistry work?

Teledentistry can be carried out through different methods. These include⁵

• Live video consultation (Synchronous), which involves real-time interaction between dentists and patients through multimedia technology. This method facilitates the immediate sharing of data and medical history, enabling dentists to assess conditions, discuss treatment options, and provide guidance directly to their patients.
• Store-and-forward (Asynchronous) involves collecting and transmitting recorded health information to a dental professional, such as X-rays, photos, or videos of dental conditions. The dentist reviews this information later to evaluate the patient's condition and provide treatment recommendations. This asynchronous approach ensures that patients receive expert advice and care without scheduling real-time consultations.
• Remote patient monitoring (RPM) allows dentists to evaluate patients from a distance. Health data, including oral health indicators, is collected from patients using electronic devices. This data is then transmitted to dental professionals, enabling them to monitor the patient's condition and provide ongoing support and guidance.
• Mobile health (mHealth): Dental care and education can be accessed through smartphones and tablets. This enables patients to easily obtain dental resources, receive appointment reminders, and engage in virtual consultations from anywhere with an internet connection. What challenges do people in remote areas face when accessing oral health? 

Access to oral care in remote areas is limited by several barriers, including:³ 

• Travel distance: Many people living in remote areas have to travel long distances, often for over an hour, just to visit a dentist because they live far from dental clinics. This incurs additional costs and causes stress, making them feel isolated and unable to seek help.
• Limited availability of specialists: Remote areas have fewer dental experts and doctors, and those who do work there often leave quickly. This makes it difficult to access specialised care, leaving people feeling helpless when they face serious dental problems.
• Low health literacy:  The culture in remote communities often has low health literacy, meaning people may not fully understand health-related information. This can lead to unhealthy behaviours and false beliefs, making them more vulnerable to health issues.
• Independence and reluctance to seek care: The culture in remote areas values independence and problem-solving skills, which often leads people to "make do" with available resources. While this can be a strength, it may also result in more severe health conditions if proper care is not sought. Additionally, people in rural areas may feel reluctant to seek care due to various barriers, leading to feelings of vulnerability and marginalisation within their community.

How can teledentistry expand access to remote areas?

Teledentistry can be beneficial to both dentists and patients, especially in rural and remote areas:⁶

• Cost-effective solutions and easier access to dental care: Teledentistry offers significant cost savings for patients by eliminating the need for expensive commutes, thereby reducing travel expenses and time commitments. Additionally, it requires fewer clinic resources, leading to lower operational costs for dental practices. Ultimately, this can result in a lesser fee structure as people gain easier access to dental care, regardless of their geographical location.
• Better quality of care: Teledentistry can improve dental care by providing personalised treatment plans and consultations, leading to more effective outcomes. Studies show its positive impact across various dental fields, demonstrating its efficacy in addressing diverse patient needs.^7,8
• Bridging oral healthcare gaps: Teledentistry can break down barriers to dental care by offering specialised services to marginalised communities, such as those with disabilities or limited financial means, ensuring everyone receives their dental attention. Bridging the gap between urban and rural healthcare, Teledentistry enhances access to essential oral health services in areas lacking adequate resources.
• Patient education: Teledentistry can be a valuable tool for patient education, as it allows dentists to explain various treatment options and diagnose comprehensively.

Limitations in teledentistry

Although teledentistry offers many benefits, it has several limitations that require attention, such as: 

• Patient confidentiality: Keeping patient information private is a big concern in teledentistry because medical records are sent electronically.  Even though efforts are made to keep it safe, there's still a risk of someone intercepting the data while it's being sent. Dentists must implement stringent measures to ensure only authorised people can access patient information. Patients also need to know that their data is being sent electronically and what risks are involved. When patients consent to teledentistry, they should be fully informed about the potential technological errors that could occur, such as misdiagnosis or incorrect treatment.¹⁰
• Medicolegal and copyright issues: Teledentistry encounters hurdles with legal regulations and copyright issues due to the absence of well-defined rules. Ensuring the quality, safety, efficiency, and effectiveness of information exchange poses challenges. Legal ambiguities regarding practitioners' rights, practice locations, and liability in case of mishaps remain unresolved in numerous jurisdictions.¹⁰
• Physical examination: Conducting a thorough check of someone's mouth over a video call can be complicated and limited because of the quality of the images sent by the patients. As such, it's important to use clear pictures that are not digitally altered so that dentists can evaluate them accurately.¹¹
• External factors: External factors like internet connectivity issues, background noise, or distractions from kids or pets can make it hard to communicate well during teledentistry appointments.¹¹
• Accessibility and experience: Some patients may face discomfort when utilising digital tools, making it challenging for them to articulate their dental issues effectively. Additionally, they might encounter difficulties correctly positioning the camera, hindering the dentist's accurate assessment and diagnosis. It’s essential for dental professionals to provide patient-friendly guidance and support to overcome these obstacles and ensure effective communication during teledentistry consultations.¹¹

FAQs

What do I need for a teledentistry appointment?

For a teledentistry appointment, you'll usually need a device with audio and video capabilities, such as a computer, tablet, or smartphone. Ensure your device is connected to the internet and has a working camera and microphone. It's also helpful to have any relevant dental records or images available for discussion with your dental care provider.

What does a teledentistry appointment look like?

Teledentistry appointments often use video conferencing platforms like Zoom for face-to-face interaction and sharing visual aids. During a teledentistry appointment, a dentist will ask questions about your symptoms and may request images for a clearer understanding. Based on this information, they'll develop a treatment plan, including temporary solutions or prescriptions if needed. 

Who is teledentistry suitable for?

Teledentistry is suitable for people who cannot be in the same physical location as their dentist and are experiencing minor oral health concerns or are due for a routine checkup. It's also helpful for patients who prefer staying at home, especially if they're feeling unwell.  You should contact your local dentist to find out if a teledentistry appointment is right for you.

Summary

Access to quality dental care is vital for maintaining oral health, yet individuals in remote areas often struggle due to distance and a scarcity of trained dental professionals. Teledentistry provides a solution by linking patients with dental professionals remotely, utilising methods like live video consultations and remote monitoring to offer cost-effective care and bridge healthcare disparities. While teledentistry offers numerous benefits, including improved access to care, it does have limitations, such as concerns regarding patient confidentiality and the inability to conduct comprehensive physical examinations. Looking ahead, ongoing advancements in teledentistry can ensure equitable access to dental care for all. It's important to note that while teledentistry enhances patient experience, it's not a comprehensive solution. Teleconsultations raise awareness and facilitate anxiety-free in-person appointments with dentists, fostering trust and confidence in dental care. Teledentistry is an integral component of dentistry, enhancing the overall patient experience and improving access to quality care.
