Dentistry in developing countries faces major challenges, with many people lacking access to even basic dental care. Despite this, progress is being made through international aid, collaborations, and local efforts.
This article looks into the current state of dentistry in developing countries, exploring access to care, disparities in untreated dental issues, and barriers to infrastructure development. By examining these statistics and the impact of aid, we aim to shed light on the challenges and advancements in improving dental care in these regions.
Access to Basic Dental Care Services
According to the World Health Organization (WHO), almost half of the world’s population, or approximately 3.5 billion people, lacks access to basic dental care services. A significant portion of those affected reside in low- and middle-income countries.
In India, the National Oral Health Programme (NOHP) aims to improve access to dental care, but most of the population, especially in rural areas, still lacks adequate services.
The program has set up dental clinics at the district level, but there is no special geriatric oral health care program, and many older adults live in poverty and social neglect.
Brazil has made significant strides in expanding access to oral health care through its Unified Health System, which provides free dental services.
Challenges remain, particularly in reaching the entire Brazilian population, with coverage stable at around 40% in recent years.
Disparities in Untreated Dental Caries and Periodontal Disease
The rates of untreated dental caries and periodontal disease are significantly higher in developing countries compared to developed countries.
The Global Burden of Disease study reported that untreated caries in permanent teeth accounted for approximately 2.03 billion prevalent cases globally, with a higher burden in low- and middle-income countries.
In Egypt, a study found that 58.5% of schoolchildren had untreated caries, with higher rates among those from lower socioeconomic backgrounds and with less maternal education.
Periodontal disease affects about 20 to 50% of the global population, with higher prevalence rates in developing countries.
For example, 36 to 63% of adults in developing nations have calculus deposits, compared to 14 to 47% in developed countries.
Socioeconomic and Access Factors
Socioeconomic status and access to dental care are key factors contributing to the disparities in untreated dental caries and periodontal disease between developing and developed countries.
A study published in the Journal of Clinical Periodontology found that people with lower socioeconomic status had a 65% higher risk of periodontitis compared to those with higher socioeconomic status.
A systematic review reported that 49% of children from low- and middle-income countries had untreated dental caries, compared to 39% in high-income countries.
Barriers to Developing Dental Care Infrastructure
Developing countries face numerous barriers to developing dental care infrastructure, including lack of access and infrastructure, insufficient workforce, financial constraints, cultural and educational factors, and systemic issues.
The dentist-to-population ratio in Africa is extremely low, averaging 1:150,000 compared to 1:2,000 in industrialized countries.
In a study conducted in Nigeria, 81.5% of dental professionals reported inadequate funding as a major barrier to providing quality dental care, while 70.4% cited a lack of proper equipment and infrastructure.
A survey of dental students in India found that 68.7% considered the high cost of dental education a significant barrier to pursuing a career in dentistry, potentially contributing to the country’s shortage of dental professionals.
Potential Solutions
To address barriers to dental care in developing countries, several strategies can be implemented, such as:
Teledentistry: This technology allows dentists to connect with patients remotely, reducing the need for in-person visits. A study in Brazil found that teledentistry could cut in-person visits by a whopping 72%, making it easier for people in remote areas to get care.
Community-based programs: In Tanzania, a school-based oral health program led to a 38% drop in cavities among students, showing how effective community-based learning can be.
Impact of International Aid Programs and Collaborations
International aid programs are making a real difference in improving dental care in developing countries:
FDI World Dental Federation: This organization has helped set up over 1,500 dental clinics in these regions, providing care to millions who previously had none.
The Smile Train: This charity, best known for cleft lip and palate surgeries, has also provided over 1.5 million dental treatments to children in need in over 90 developing countries.
The Global Child Dental Fund: This UK charity has trained over 5,000 dental professionals in developing countries and provided care to over 100,000 children.
These examples show the incredible impact that international aid and collaboration can have on improving dental health in communities that need it most.
The lack of access to quality dental care in developing countries is a significant issue, as highlighted by high rates of untreated dental problems and barriers to infrastructure development. International aid programs have made a positive impact through funding, training, and advocacy.
However, ongoing efforts are needed to address disparities between developing and developed countries. By focusing on sustainable infrastructure, strengthening the dental workforce, and promoting oral health education, we can strive for equitable access to dental care for all.
