Abstract:The aim of this study was to investigate the effects of swallowing exercises on oral function in independent elderly patients visiting the Department of Prosthodontics at Tokyo Dental College Chiba Hospital. Twenty-nine patients aged over 65 years (15 men and 14 women; mean age, 75.0 years) in whom treatment was completed at this college were enrolled in the study. The patients were instructed on how to perform swallowing exercises monthly (including at baseline) for the first 2 months from the start of the st… Show more
“…Furthermore, since sarcopenia is a systemic process [15,21], it has been recommended to perform a holistic training involving all muscle groups [15]. In fact, it has been documented that both masticatory and swallowing functions can be improved through muscle-strengthening exercises [169,170]. Several studies reported enhancements in subjective chewing ability, swallowing function, salivation, relief of oral dryness, and oral-health quality of life.…”

Aging is accompanied by profound changes in many physiological functions, leading to a decreased ability to cope with stressors. Many changes are subtle, but can negatively affect nutrient intake, leading to overt malnutrition. Poor oral health may affect food selection and nutrient intake, leading to malnutrition and, consequently, to frailty and sarcopenia. On the other hand, it has been highlighted that sarcopenia is a whole-body process also affecting muscles dedicated to chewing and swallowing. Hence, muscle decline of these muscle groups may also have a negative impact on nutrient intake, increasing the risk for malnutrition. The interplay between oral diseases and malnutrition with frailty and sarcopenia may be explained through biological and environmental factors that are linked to the common burden of inflammation and oxidative stress. The presence of oral problems, alone or in combination with sarcopenia, may thus represent the biological substratum of the disabling cascade experienced by many frail individuals. A multimodal and multidisciplinary approach, including personalized dietary counselling and oral health care, may thus be helpful to better manage the complexity of older people. Furthermore, preventive strategies applied throughout the lifetime could help to preserve both oral and muscle function later in life. Here, we provide an overview on the relevance of poor oral health as a determinant of malnutrition and sarcopenia.

“…Moreover, performing oral exercises (i.e., neck exercises, massaging salivary glands, vocal exercises) may reduce the effects of the direct and indirect pathway on QoL. Oral exercise is effective in improving the rate of oral diadochokinesis and reducing xerostomia, dysphagia and poor masticatory performance (39). In addition, vocal exercise by pronouncing the syllables /pa/, /ta/, or /ka/ involves the use of the front (lips), middle (tip of the tongue), and back of the mouth (posterior tongue), respectively and this exercise could effectively train of oral function (40).…”
Background: The impact of poor oral health in older adults affecting their quality of life is a public health problem. This study assessed the mediating effects of dental status, occlusal condition, dysphagia and masticatory performance on the association between xerostomia and oral health-related quality of life (OHRQoL) in the older population. Methods: Stratified cluster sampling method was used to recuit 1100 community-dwelling adults aged 65 years and older from Kaohsiung, Taiwan. Community care centers were randomly selected based on their geographic classifications (urban, rural, and mountainous areas). Assessments of dental status and occlusal condition were performed by dentists. Information on demographics, physical function, xerostomia dysphagia and depression was collected using face-to-face interview. Masticatory performance was evaluated using color-changeable chewing gum. OHRQoL was measured using Geriatric Oral Health Assessment Index. Hierarchical regression models were utilized to assess the relationship between OHRQoL and physical function, dental status and oral function in older adults. Path analysis was used to estimate direct and indirect pathways between xerostomia and OHRQoL.Results: Participants with xerostomia had a 0.17 OHRQoL reduction (p< .001) comparing to the non-xerostomia, and the direct effect was accounted for 85.0% of the total effect. The dysphagia and the poor masticatory performance were found to have a significant mediating effect on the association between xerostomia and OHRQoL (βs = 0.17 and −0.09, respectively, both p< .001; βs = 0.05 and −0.08, respectively, both p< .001) moreover, potential mediating influences of the number of functional teeth (βs = −0.11 and −0.44, respectively, both p < .001) and poor occlusal condition (βs = 0.09 and 0.12, respectively, both p < .05) on the relationship between xerostomia and masticatory performance were obervered.Conclusions: Dysphagia and poor masticatory performance may serve as a pathway of which xerostomia affects quality of life. Providing early oral function intervention may be a valuable and actionable target for older adults to maintain their quality of life. Our results further suggest that checkup and screening for oral dysfunction is essential to prevent or delay the onset of complications.

“…stimulating salivary grands and oral diadochokinesis [ 17 ], showed nutritional improvement [ 18 ] and also improvement of feeding function of elderly subjects [ 19 ]. Swallowing exercise showed improvement of salivary parameters, such as saliva flow rate, salivary pH at rest, and buffering capacity, suggesting the improvement of oral functions [ 20 ]. Thus, oral training is expected as an alternative exercise, which potentially contribute to immune functions of these elder people.…”
BackgroundOral functional ability decreases with age, and systemic immunological ability and quality of life can also deteriorate. Continuous moderate whole-body exercise for older people is known to improve oral functional and their immunological abilities. Here, we evaluated the effect of oral exercise as an alternative training method for highly older people who cannot perform whole-body exercises.MethodsUnstimulated whole saliva samples had been collected for three times before training as baseline data and one time after 3 and 6 weeks of training each. Participants were instructed to conduct self-massage; their tongues were used to press their orbicularis oris muscle and buccinators, and instructed to perform bilateral massage of three major glands for facilitating saliva secretion. Medical histories, daily life habits and characteristics were also collected.ResultsTotally 30 participants (84.2 ± 8.5 years) were enrolled. In contrast to previous researches, increase in salivary Immunoglobulin A (IgA) after the training was not observed. Interestingly, hierarchical clustering analyses revealed clear individual variations as two prominent clusters and a strong positive correlation between stimulated saliva flow rate and IgA flow rate, regardless of the continuous oral functional exercise. Only body mass index (BMI) showed significant differences between the two groups (Z = 2.06, P = 0.039, Wilcoxon rank-sum test) among all collected parameters.ConclusionOral functional training limitedly effects on salivary parameters of highly older people. On the other hand, BMI characterized salivary features more than any other parameters, such as the presence of diseases or medication use in these people.
