Gerodontology Lab
Machine-translated · View original
A gerodontology lab that supports older adults' wish to eat and to speak, starting from the mouth.

AboutAbout the lab
Shaping dental care for the age of 100-year lives.
The Gerodontology Lab engages in clinical care, education, and research on the dental care needed in a super-aged society.
The lab supports the oral health of people with multiple illnesses, people who need long-term care, people undergoing cancer treatment, and people with dementia, working together with medicine, dentistry, and a range of other professions.
Centered on clinical research involving human participants, the lab also conducts basic research in molecular biology, pharmacology, and bacteriology to complement it.
The lab places importance on assessing oral function, swallowing function, nutrition, and overall health together.

ResearchResearch themes
Research centers on practical, applied studies that respond to the dental needs of a super-aged society. In multicenter collaborations, the lab builds evidence for maintaining oral health to extend healthy life expectancy, and studies how oral health should be managed so that people who need care or treatment for cancer or dementia can keep living the way they wish.
*Illustrative imageOral frailty and decline in oral function
The lab investigates how oral frailty and declining oral function affect the whole body, develops and tests programs for prevention and improvement, and develops devices for assessment and training.
*Illustrative imageOral care before and after surgery
The lab examines the effects of multidisciplinary perioperative oral management from many angles, including bacteria, cells, psychology, and nutrition. It also studies oral management during hematopoietic stem cell transplantation.
*Illustrative imageComprehensive support for dysphagia
The lab tests the effects of approaches for dysphagia that combine environmental adjustment by multidisciplinary teams, physical therapy, dental treatment including jaw prosthetics, oral health management, and nutritional support.
*Illustrative imageOral health management for people with dementia or care needs
The lab studies how oral health should best be managed for people with dementia or psychiatric disorders and for older adults who need long-term care.
