와타나베 유타카 교수의 연구실은 노화와 관련된 구강기능 저하, 특히 구강프리플라티(oral frailty)와 신체적·정신적 기능 저하 간의 연관성을 중심으로 연구를 진행하고 있습니다. 고령자에서의 산소력, 근육 두께, 물리적 기능 저하와의 연관성을 규명하며, 조기 진단과 예방 전략 개발에 초점을 맞추고 있습니다. 특히 기억장애의 조기 징후로 나타날 수 있는 구강운동 기능 저하의 임상적 의의를 탐색하고 있습니다.

Age-related differences in oral function were found in older adults. Moreover, frail older individuals had significantly poorer oral function than prefrail and robust individuals. The risk of frailty was associated with lower occlusal force, masseter muscle thickness, and ODK rate.
Oral frailty is defined as a decrease in oral function accompanied by a decrease in mental and physical functions. Studies showing that people with oral frailty are at high risk of physical frailty, sarcopenia, severe conditions requiring nursing care and death have been reported in Japan. An increase in life expectancy and maintenance of teeth result in a decrease in the effect of the number of teeth. In contrast, a decrease in oral function as a result of aging has been suggested to have major
Among rural community-dwelling older adults, the rate of oral frailty was 22.5% and that of oral hypofunction was 43.6%.
Oral motor skill, such as lip movement, might be impaired in patients with MCI. Detecting decreasing oral motor dexterity supports the early detection of MCI, and might be key to improve the prognosis of dementia. Geriatr Gerontol Int 2018; 18: 790-798.
Subjective masticatory functionSMF and OMF were associated with different factors, suggesting that both mental and physical factors should be taken into consideration when treating decreased masticatory function.
