Dental Public Health Lab
Machine-translated · View original
A dental public health lab that approaches disease prevention and health promotion through oral health.

AboutAbout the lab
Supporting society's health through oral health.
The Dental Public Health Lab aims to contribute to disease prevention and health promotion through oral health.
Students learn how to plan and conduct epidemiological surveys and studies, interpret the results correctly, and share them with local and international communities.
The lab works closely with dentists and dental hygienists at local governments and public health centers, and together they consider how community dental health should be run.
Undergraduate students, graduate students, international students, and the lab's staff interact with one another while each pursues their own research topic.
Key terms
- Epidemiology
- The study of how diseases occur in large groups of people, and of their causes and related factors
- Periodontal disease
- A disease in which bacterial inflammation gradually destroys the gums and the bone that supports the teeth
- Machine learning
- A technology in which computers learn patterns from large amounts of data and use them to make predictions or classifications
ResearchResearch themes
The lab uses epidemiological methods to investigate how oral health and oral function relate to nutrition and systemic disease. It also uses machine learning and dental big data to make future projections and to analyze how dental care systems work.
*Illustrative imageOral Health and Function, Nutrition, and Diet
The lab investigates how oral functions such as chewing and swallowing, and oral health in general, relate to eating habits and nutritional status. This research focuses on older adults.
*Illustrative imagePeriodontal Disease and Systemic Disease
The lab investigates associations between periodontal disease and systemic diseases such as kidney disease and osteoporosis, using data from community-dwelling people and other populations.
*Illustrative imagePredicting the Future of Periodontal Disease with Machine Learning
This research uses machine learning to predict the future prevalence of periodontal disease. It aims to anticipate what periodontal disease will look like in an era when more people keep many of their teeth.
*Illustrative imageAnalyzing Dental Care with Dental Big Data
The lab uses dental big data to understand how dental care delivery systems actually work and to verify the effectiveness of treatments. It also studies dental visits by people with disabilities and people with diabetes.
