My greatest hope is to see oral health become a routine and essential part of diabetes care—embedded in policy, prevention programs, and daily clinical practice. Dentists should be trained and empowered to identify people at risk and to collaborate closely with physicians and educators.
Living with type 1 diabetes himself, Dr. Végh combines personal experience with scientific inquiry to advance integrative, prevention-oriented care. He is actively engaged in international collaborations, public education, and global initiatives that promote the inclusion of oral health in chronic-disease management.
How does your research relate to the SDGs?
Our research directly supports Sustainable Development Goal 3 (Good Health and Well-Being) by addressing an often-overlooked link between diabetes mellitus and oral health. The condition affects more than 500 million people globally, and its oral manifestations—such as periodontitis, delayed wound healing, and increased infection risk—have a profound impact on quality of life and systemic outcomes.
At the Semmelweis University Diabetes Dental Research Group, our mission is to bridge the gap between dentistry and systemic medicine. We focus on early screening for undiagnosed diabetes through salivary biomarkers, explore the bidirectional relationship between glycaemic control and oral inflammation, and develop educational programs to raise awareness among healthcare professionals and people living with diabetes.
By combining clinical research, public health education, and interdisciplinary collaboration, we aim to integrate oral health into comprehensive diabetes care—contributing to prevention, health equity, and improved well-being worldwide.
Why did you decide to go into your field of research?
My motivation for this field is deeply personal: I was diagnosed with type 1 diabetes mellitus 16 years ago, during my dental studies. Living with the condition gave me first-hand insight into its daily challenges and its wide-ranging systemic impact. I realized how rarely oral health was considered in diabetes management, despite its clear relevance.
This experience inspired me to dedicate my career to exploring the interconnection between systemic health and oral conditions. Over time, I established the Diabetes Dental Research Group at Semmelweis University, bringing together dentists, endocrinologists, and public-health professionals to translate scientific findings into clinical benefit.
For me, this research is not only academic—it is personal. I believe every person living with diabetes deserves a healthcare system that recognizes the mouth as part of the body, not apart from it.
How has knowledge of the topic developed over the course of your career?
When I began my research more than a decade ago, the oral complications of diabetes mellitus were acknowledged but poorly understood in clinical practice. Most discussions focused solely on periodontal disease, while other areas—such as implant success rates, wound healing, salivary diagnostics, and microbiome alterations—were less explored.
In recent years, the field has evolved dramatically. Large-scale studies have confirmed the bidirectional relationship between periodontal inflammation and glycaemic control, and innovative technologies now enable non-invasive saliva-based glucose detection. Within implant dentistry, our group and collaborators have shown that with proper metabolic control and soft-tissue management, people with diabetes can achieve outcomes comparable to individuals without diabetes—particularly when tissue-friendly materials like zirconia implants are used.
This progress has transformed our understanding of oral-systemic interactions and highlights the importance of interdisciplinary, evidence-based approaches in modern dentistry.
What challenges do those from low- and middle-income countries in particular face?
The burden of diabetes mellitus is growing most rapidly in low- and middle-income countries, where access to both medical and dental care remains limited. In these settings, oral health is rarely integrated into diabetes management programs, leading to undiagnosed cases and untreated oral complications.
People with diabetes in these regions often face barriers such as high treatment costs, limited awareness, and inadequate preventive infrastructure. Moreover, healthcare providers may not receive sufficient training on the systemic consequences of oral inflammation.
Through international collaborations, our team works to develop low-cost educational and screening models that can be implemented even in resource-constrained environments. We believe that true progress must include capacity building, knowledge transfer, and equitable access to preventive services. Without tackling these disparities, the global goals of SDG 3 will remain out of reach.
What are your hopes for progress in the future?
My greatest hope is to see oral health become a routine and essential part of diabetes care—embedded in policy, prevention programs, and daily clinical practice. Dentists should be trained and empowered to identify people at risk and to collaborate closely with physicians and educators.
Technological innovations such as AI-assisted diagnostics, digital imaging, and salivary biomarker analysis will likely revolutionize early detection and personalized prevention strategies. In our group, we are developing digital and biological tools that could help identify metabolic imbalance during routine dental visits.
Ultimately, I envision a healthcare model where integration replaces fragmentation—where disciplines work together, data guides prevention, and people with diabetes receive comprehensive, person-centred care. Through international collaboration and shared scientific commitment, we can make this vision a reality.
