“…Variabilities in socioeconomic factors and social activity may be important in uences on differences between men and women, and these factors may explain the lack of association between tooth loss and grip strength in women. In addition, reported results are not directly comparable, since there were differences in age distribution, methods of measuring grip strength, and adjustment for confounding factors in the previous studies [14,17,18,32] . Therefore, gender differences in the relationship between the number of teeth and grip strength is intriguing and deserves further study.…”

“…Grip strength is a commonly used indicator of total body strength and is a known predictor of disability and mortality [31] . A recent Chinese study showed no link between tooth loss and grip strength in people over the age of 60 [32] . In a Japanese community study involving participants ages 40 to 70, there was also no correlation found between the number of teeth and grip strength in either sex [18] .…”

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.

“…The current study observed an association between PT and relative handgrip strength, regardless of the status of continuous or categorical variable, as PT was a categorical variable in the crude model and the model adjusted for covariates. A study of Chinese individuals below the age of 60 years by Zhou et al [26] employed the average number of missing teeth as the cut-off value for tooth loss and reported an association between tooth loss and relative handgrip strength. The abovementioned results were similar to the current results.…”

Grip strength is a simple indicator of physical strength and is closely associated with systemic health. Conversely, oral health has also been reported to have an important association with systemic health. The present study aimed to assess the effect of oral health status on relative handgrip strength. The data pertaining to 11,337 participants were obtained by means of the seventh Korea National Health and Nutrition Survey (2016 to 2018). Oral health status was evaluated on the basis of the presence of periodontitis and number of remaining teeth (PT, present teeth). Relative handgrip strength was evaluated by means of a digital dynamometer and the value pertaining to the lower 25% of measurements was used as the quartile by gender. The association between oral health status and relative handgrip strength was evaluated by means of multiple regression analysis and multiple logistic regression analysis with covariate correction. Analysis of the crude model revealed a significant association in the group of patients with periodontal disease (odds ratio = 1.69, 95% confidence interval: 1.51–1.89). However, analysis with adjusted covariates revealed that the association was not statistically significant. Moreover, statistical analysis after adjustment for covariates revealed a consistent correlation between PT and relative handgrip strength as categorical and continuous variables. Hence, the present study observed a significant association between oral health status and relative handgrip strength among the Korean adult population.

“…This might also increase RA disease activity, which is influenced by dietary factors as well [ 27 ]. Furthermore, tooth loss was found to affect muscle and handgrip strength in the general population [ 28 ], which also might indicate a complex interrelation between tooth loss and RA (and SA) activity. Furthermore, the occurrence of tooth loss as a potential consequence of periodontal bone loss might also affect the PISA results of the current study cohort.…”

Background: The aim of this cross-sectional study was to investigate potential associations between periodontal inflamed surface area (PISA) and tooth loss with disease-related parameters in patients with rheumatoid arthritis (RA) and ankylosing spondylitis (AS). Methods: Patients who attended the Department of Nephrology and Rheumatology, University Medical Centre Goettingen, Germany, were included. The oral examination comprised the detection of the number of remaining teeth and periodontal condition based on staging and grading matrix. Based on periodontal pockets with positive bleeding on probing, the periodontal inflamed surface area (PISA) was determined. Disease related parameters were extracted from the patients’ records. Results: In total, 101 (RA) and 32 participants (AS) were included. Patients with RA had 22.85 ± 4.26 and AS patients 24.34 ± 5.47 remaining teeth (p < 0.01). Periodontitis stage III and IV was present in 91% (RA) and 81.2% (AS) of patients (p = 0.04). Associations between PISA and disease-related parameters were not found in both groups (p > 0.05). In RA, a higher age (p < 0.01), C-reactive protein (p = 0.02), disease activity (p < 0.01) and prednisolone intake (p < 0.01) were associated with fewer remaining teeth. In AS, a higher age (p = 0.02) and increased Bath Ankylosing Spondylitis Metrology Index (p = 0.02) were associated with a lower number of remaining teeth. Conclusions: Tooth loss is associated with disease activity, especially in RA individuals. Dental care to prevent tooth loss might be recommendable to positively influence oral health condition and disease activity in RA and SA patients.
