This video features an interview with Dr. Hwan Lee, a distinguished pediatric dentist and public health expert, who discusses the critical importance of oral health within the broader context of global health. Dr. Lee outlines three compelling reasons why oral health is a vital global health concern: its intrinsic connection to overall body health, the staggering global burden of preventable oral diseases affecting billions, and the high economic cost associated with these conditions. She identifies the major oral health problems worldwide and highlights the significant disparities in access to care, with vulnerable and marginalized populations being disproportionately affected. Finally, Dr. Lee emphasizes strategies for integrating oral health into primary healthcare, training a diverse workforce, ensuring universal access to essential services, and fostering multi-sectoral global collaborations to elevate oral health on the international agenda.
Summarizing Global Oral Health with Dr. Hwan Lee
0:00 Introduction to Dr. Hwan Lee: Dr. Lee is introduced as a board-certified pediatric dentist in the US and Kenya, holding advanced degrees in public health. She directs the Global Maternal and Child Oral Health Center at Seoul National University and previously chaired the World Federation of Public Health Associations Oral Health Working Group.
1:47 Session Objectives: The discussion aims for learners to understand the importance of oral health to global health, the burden of oral diseases, critical national measures to address these issues, and global cooperation in oral health.
Body Connection: Oral health is intrinsically linked to general health, affecting eating, breathing, and speaking, and is associated with heart disease, diabetes, and birth outcomes. Oral conditions share common risk factors with major non-communicable diseases.
Global Burden: Oral diseases are the most common, neglected, and expensive globally, affecting 3.5 billion people (nearly half the world's population). Untreated tooth decay alone affects 2 billion.
Preventability: Most oral diseases are completely preventable and treatable, with simple interventions like fluoride and basic preventive care making massive impacts, especially in resource-limited settings.
The Big Four: Untreated tooth decay in adult teeth (2 billion people), untreated tooth decay in primary/baby teeth (0.5 billion children), severe gum disease (periodontitis, 1 billion cases), and complete tooth loss (edentulism, 350 million people).
Economic Impact: In 2019, direct spending on oral health problems was $387 billion USD, with an additional $300 billion USD in lost productivity, totaling nearly $700 billion USD on largely preventable diseases.
7:48 Who is Most Affected by Oral Health Disparities: The 2019 Lancet report highlights massive oral health inequity. The inverse care law applies, where those most in need have the least access. Vulnerable communities, rural populations, low-income families, indigenous populations, and people with disabilities are hit hardest due to maldistribution and shortage of dental providers.
Reposition Oral Health as Primary Care: Oral health screening should be routine in community health centers.
Train Existing Healthcare Workforce: Expand training for dentists, hygienists, and therapists, but also nurses, community health workers, and primary care providers, to deliver essential oral health services.
Universal Health Coverage: Essential, preventive oral health services (like vaccines and maternal care) should be covered under universal healthcare, accessible to everyone without financial burden.
WHO Leadership: The World Health Organization (WHO) is leading efforts, with their statement "No health without oral health," to place oral health on the global agenda.
Key Organizations: Organizations like the International Association for Dental Research (IADR) drive science, and the World Dental Federation (FDI) mobilizes dental professionals and policy changes.
Integrate with Broader Health Agenda: Success requires collaboration with non-dental organizations to integrate oral health into larger health agendas (e.g., public health, maternal and child health - MCH).
Cross-Sector Collaboration: Collaboration with non-health communities (like education) is vital to elevate the public perception of oral health's importance.
13:57 Conclusion: The speaker thanks Dr. Lee for her articulate explanation of oral health's global importance, the burden of disease, affected populations, national measures, and global cooperation. The session emphasizes the need for learners to prioritize oral health in their global health understanding.
