We aimed to investigate this association in older Japanese adults. This cross-sectional study included 7,984 Japanese participants aged ≥65 years from...
Introduction:
Oral frailty describes a trivial decline in the oral function and is considered to be related to frailty. Thus, effective management of oral frailty could prevent or ameliorate physical frailty and the need for care. However, there is a lack of consensus regarding specific interventions for oral frailty. In this cluster-randomized co...

In recent years, sarcopenia prevention and flail prevention are regarded as important. As a way to achieve healthy longevity, dental care that incorporates a nutritional perspective is necessary. On the other hand, dentistry has not incorporated the viewpoint of masticatory disorders due to motor disorders in the diagnosis of masticatory disorders....
Aim For achieving healthy aging, frailty prevention is essential. Because it is reported that accumulated declines in multiple oral functions (i.e. oral frailty) could lead to frailty progression, detailed countermeasures for oral frailty are currently required. However, dentists of community dental clinics don’t even know a prevalence of oral frai...

... In Japan, following the COVID-19 pandemic, the use of telemedicine devices for doctor-to-patient interactions has been progressing with scattered reports. However, legislative developments for doctor-to-doctor clinical support have been lagging, especially in emergency outpatient settings [6,7]. ...
... Even when indirect training is provided, some patients may fail to (or cannot) continue the training long enough. However, another study reported that tongue protrusion was significantly less frequent in patients with Down syndrome who received indirect training than in those who did not [18]. Active, indirect training is desirable for eligible patients. ...
... These conditions are associated with disability and mortality [26,27]. Considering the above findings, in conjunction with the evidence supporting the effect of the number of functional teeth on disability and mortality [7,8], we hypothesized that the number of functional teeth is inversely associated with the DII score. If an association between the number of functional teeth and the DII score is found, these findings would support the importance of dental prostheses for healthy longevity from the viewpoint of a healthy diet. ...

... Recent developments in adequate nutritional support and functional training have enabled the improvement of nutrient intake in individuals with tooth loss [36,37]. Kikutani et al. reported that life expectancy could be improved by the use of dentures in older adults with loss of occlusal support who were under home care in Japan [38]. However, the authors also stated that if only participants aged > 80 years were stratified, the statistical significance of occlusal support against life expectancy was lost. ...
... However, many patients in the city, but living in remote urban areas, would also benefit from telemedicine because it allows patients to connect with health professionals without the need to travel long distances (Imberti et al. 2021), resulting in more timely and efficient care. In addition, this approach also facilitates care for people with reduced mobility or disabilities, improving their quality of life (Petretto et al. 2023;Tamura et al. 2023). ...
... A prior study also indicated that an oral functional training intervention, including tongue motion, was associated with decreased tongue coating. While TCI could be a potential proxy indicator of tongue motor function, a previous study provided a safer, more straightforward measurement of tongue motor function [31]. Rinsing effectively prevents oral disease [32], and vigorous rinsing ability requires adequate muscle mass and coordination of the lips, buccinator, and tongue. ...
... Improving the chewing function of older individuals to reduce medical expenses and increase the HRQoL is an important issue in an aging society. The motor functions of the tongue and lips deteriorate with age then affect masticatory performance [5]. Most investigations focus on the dental status regarding chewing ability [6,7]. ...
... Depression and self-rated health status also appear to have a significant correlation with oral health, supporting previous studies that oral health is inversely related to depression [74][75][76]. The significant correlation between masticatory ability and self-rated health status is selfexplanatory in that masticatory movement is important for eating enjoyment without limiting the variety of food and nutrition supply [77]. Thus, it is suggested that for proper management of depression in the elderly group, a holistic healthcare program comprising not only psychological care but also oral care with proper diet and lifestyle is needed. ...
... Frailty can lead to a decline in various physical and physiological declines that can easily lead to health disadvantages, such as weight loss, fatigue, reduced walking speed, decreased grip strength and reduced physical activity (1,2) . Similarly, oral frailty is a multifaceted condition with widespread implications for overall health and well-being in the elderly because it implies deterioration of oral tissues, immune response and microbial balance, leading to an increased susceptibility to oral diseases and conditions (1)(2)(3)(4) . Addressing oral frailty through preventive measures, early detection and appropriate interventions is essential to promote healthy ageing and improve the quality of life of the elderly (1)(2)(3)(4) . ...
... Currently, there is no systematic intervention plan to improve the oral frailty or oral function. However, a study conducted on older adults who had poor oral function showed significant improvement in their oral function after undergoing a regimen of oral exercises, mouthopening training, tongue-pressure training, articulation training, and masticatory training [35]. Based on these findings, this study intended to suggest aspects should be considered when developing interventions to improve oral function in Korean older adults. ...
