Relationship between occlusal force and endothelial function in community‐dwelling elderly women: A pilot study

Abstract

Objective In this study, age, endothelial function as flow‐mediated dilation (FMD), occlusal force, grip strength, and advanced glycation end products (AGEs) were obtained. AGEs were measured as indicators of aging, while grip strength was measured as an indicator of muscle strength. This study aimed to explain the relationship between occlusal force and endothelial function and determine whether occlusal force can be a new indicator in community preventative care projects. Materials and Methods In 38 community‐dwelling women (age, 76.7 ± 5.7 years), the occlusal force and grip strength were measured, the endothelial function was evaluated by FMD, and AGEs were obtained. The relationship between occlusal force, measurement items, and factors were investigated independently related to endothelial function. Results There were significant correlations between occlusal force and grip strength (r = .54, p < .01). The degree of FMD was significantly associated with occlusal force (r = .60, p < .01) and grip strength (r = .35, p < .05) or increase in AGEs (r = −.37, p < .05). Multiple regression analysis revealed that occlusal force was significantly associated with the degree of FMD (p < .01). Conclusion Occlusal force can be an important indicator of endothelial function in the community‐dwelling elderly. This study may help understand the general health of the elderly in communities.

Usefulness and Validity of a Jaw-Closing Force Meter in Older Adults

“…Based on these results, it is possible to evaluate the values of jaw-closing force and occlusal force of older edentulous patients as similar; although, the measured values (N) do not coincide. With regard to the muscle mass and strength of the masseter muscles, an association with grip strength [ 17 ], an association with increased risk of physical dysfunction independent of confounding factors such as the number of remaining teeth [ 18 ], and an association between occlusal force and vascular endothelial function [ 19 ] have been reported in older persons living in the community. The relationship between oral function and not only perioral muscles but also whole-body muscular strength and function has been elucidated, and evaluation of jaw-closing force with the JCF meter may be useful for health management of older adults.…”
