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.
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.
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).
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.
本研究获得了年龄、血流介导的舒张功能（FMD）、咬合力、握力和晚期糖基化终产物（AGEs）等指标。AGEs 被作为衰老的指标，而握力被作为肌肉力量的指标。本研究旨在解释咬合力与内皮功能之间的关系，并确定咬合力是否可以成为社区预防保健项目中的一个新指标。
在 38 名社区居住的女性（年龄 76.7±5.7 岁）中，测量了咬合力和握力，通过 FMD 评估内皮功能，并获得了 AGEs。独立研究了咬合力与测量项目以及与内皮功能相关的因素之间的关系。
咬合力与握力之间存在显著相关性（r=.54，p<.01）。FMD 程度与咬合力（r=.60，p<.01）和握力（r=.35，p<.05）或 AGEs 增加（r=-.37，p<.05）显著相关。多元回归分析显示，咬合力与 FMD 程度显著相关（p<.01）。
咬合力可以作为社区居住的老年人内皮功能的一个重要指标。本研究可能有助于了解社区老年人的整体健康状况。
