“…Reduced occlusal force, decreased tongue pressure, decreased masticatory function, and deterioration of the swallowing function were significantly more common in the frailty group, a result that matches that of past research. Meanwhile, existing reports on the relationship between sarcopenia and occlusal force assessed using number of teeth or pressure indicating film have not yielded consistent results [ 33 ]. For example, in two directly contradictory reports, Tanaka et al [ 10 ] found a significant relationship between the number of teeth and sarcopenia, but no significant difference in the relationship between sarcopenia and occlusal force measured via pressure-indicating film.…”

Oral hypofunction is a new concept that addresses the oral function of older adults. Few studies have investigated the relationship between oral hypofunction and general health conditions such as frailty, sarcopenia, and mild cognitive impairment. This paper explores these relationships in a large-scale, cross-sectional cohort study. The relationships of oral hypofunction with frailty, sarcopenia, and mild cognitive impairment were examined using data from 832 individuals who participated in the 2018 health survey of the residents of Tarumizu City, Kagoshima Prefecture, Japan. Individuals with frailty, sarcopenia, and mild cognitive impairment had significantly higher rates of oral hypofunction. Frailty was independently associated with deterioration of the swallowing function (odds ratio 2.56; 95% confidence interval, 1.26–5.20), and mild cognitive impairment was independently associated with reduced occlusal force (odds ratio 1.48; 95% confidence interval, 1.05–2.08) and decreased tongue pressure (odds ratio 1.77; 95% confidence interval, 1.28–2.43). There was no independent association found between sarcopenia and oral function. In conclusion, early intervention for related factors such as deterioration of the swallowing function in frailty, reduced occlusal force, and decreased tongue pressure in mild cognitive impairment could lead to the prevention of general hypofunction in older adults.

“…To the best of our knowledge, only one study has reported that handgrip strength is positively associated with masticatory performance measured with gummy jellies [ 7 ]. A recent review speculated that the mechanisms of the association between oral health and sarcopenia involve three pathways in which worsening of oral health causes poor dietary intake, neuromuscular system failure, and a loss of muscle strength caused by inflammation [ 6 ]. Meanwhile, we found associations between NT and a decline in handgrip strength, or possible sarcopenia, after adjusting for all confounders.…”

“…Some studies have reported that the number of remaining teeth and/or objective masticatory performance is related to handgrip strength, skeletal muscle mass, or sarcopenia [ 4 , 7 – 11 ]. However, because there are few reports and inconsistent results regarding the association between oral health and sarcopenia, further studies are required to address this issue [ 6 ].…”

Number of teeth and masticatory function are associated with sarcopenia and diabetes mellitus status among community-dwelling older adults: A Shimane CoHRE study

Objectives We aimed to examine the number of teeth and masticatory function as oral health indices and clarify their roles in the pathogenesis of sarcopenia and diabetes mellitus in community-dwelling older adults. Subjects and methods This cross-sectional study was conducted with 635 older adults in Ohnan, Shimane Prefecture, in rural Japan. The number of teeth and masticatory function (measured by the number of gummy jelly pieces collected after chewing) were evaluated by dental hygienists. Sarcopenia status was assessed using handgrip strength, skeletal muscle index, calf circumference, and a possible sarcopenia diagnosis based on the Asian Working Group for Sarcopenia 2019. Diabetes mellitus status was defined as a hemoglobin A1c level ≥6.5% or self-reported diabetes. A multivariable logistic regression model was used to analyze the association between oral health, sarcopenia, and diabetes mellitus after adjusting for confounders. Results After adjusting for all confounders, logistic regression analysis showed that the number of remaining teeth was negatively associated with a low level of handgrip strength (odds ratio [OR], 0.961; 95% confidence interval [CI], 0.932–0.992) and possible sarcopenia (OR, 0.949; 95% CI, 0.907–0.992). Higher levels of masticatory function were also negatively associated with a low level of handgrip strength (OR, 0.965; 95% CI, 0.941–0.990) and possible sarcopenia (OR, 0.941; 95% CI, 0.904–0.979). Logistic regression analysis showed that the number of remaining teeth and a higher level of masticatory function were negatively associated with diabetes mellitus (OR, 0.978; 95% CI, 0.957–0.999; OR, 0.976; 95% CI, 0.960–0.992, respectively). Conclusion Our findings suggest that improvement in oral health, including the maintenance of masticatory function and remaining teeth, may contribute to the prevention of sarcopenia and diabetes mellitus in older adults.

Background: Both sarcopenia and loss of teeth are associated with aging. The purpose of this study was to investigate potential relationships between tooth loss and sarcopenia and components of sarcopenia, including declining muscle mass, muscle strength, and physical performance, in Chinese suburban community-dwelling older adults.Methods: The subjects were 1494 people over 60 years of age (average age: 71.64 ± 5.97 years；men, n=609) from Chongming District of Shanghai and Hangu District of Tianjin. The Asian Working Group for Sarcopenia (AWGS) criteria were used to define sarcopenia. The three basic diagnostic components of sarcopenia (muscle mass, muscle strength, and physical performance) were assessed using a bioelectrical impedance analyzer, a grip strength test, and a four-meter walk test, respectively. The subjects were divided into groups depending on self-reported loss of teeth. Results: After adjusting for confounding variables, we found no correlation between tooth loss and sarcopenia or muscle mass. However, the walking speed of female participants with at least 10 teeth lost was 0.059 m/s slower than that of participants with fewer than 10 teeth lost (P＜0.001), and grip strength was 1.577 kg lower among male participants with at least 10 teeth lost than among males with fewer than 10 teeth lost (P =0.023).Conclusion: Our results suggest that tooth loss is negatively correlated with muscle strength in males and average walking speed in females. These results are consistent with the importance of good oral hygiene in preventing declines of physical performance in older adults.
