Objective The purpose of this study was to elucidate the associations between muscle strength and several oral functions in a large cohort of community‐dwelling, 82‐ to 84‐year‐old community‐dwelling Japanese people. Background data discussing the present status of the field Several studies have examined the relationships between physical performance and oral functions. However, no studies have investigated the associations of muscle strength with various objectively evaluated oral functional parameters in a large cohort of very old adults. Materials and Methods This study included 809 community‐dwelling Japanese people (407 men and 402 women) aged 82‐84 years. The oral functions examined were the maximal occlusal force, masticatory performance, stimulated salivary flow rate, repetitive saliva‐swallowing test ( RSST ) score, tongue pressure and mouth‐opening distance. Handgrip strength was measured, and its correlations with oral functions were assessed. Multiple linear and logistic regression analyses were performed to investigate the relationships between oral functions and handgrip strength. Results Multivariate analysis revealed that handgrip strength was correlated with not only the maximal occlusal force, masticatory performance and tongue pressure but also the RSST score and mouth‐opening distance after adjustment for sex, number of teeth, use of removable denture, periodontal condition, instrumental activities of daily living, body mass index. When we examine the elderly people whose handgrip strength is declining, we should predict that their various oral functions may be declining. Conclusion Handgrip strength was related to various oral functions after adjustment for the number of teeth in this population of community‐dwelling 82‐ to 84‐year‐old Japanese.
