目的：保持自然牙列和/或修复修复对于良好的咀嚼功能是必要的。尽管身体和口腔功能等其他因素对咀嚼性能也很重要，但只有少数研究评估了它们的作用。本研究的目的是在维持和/或重建所有咬合支撑区的同时，评估与老年人咀嚼功能相关的因素。方法：本研究以横断面研究的形式设计和实施，共有262名参与者(平均年龄：74.2+/-5.9岁)参加了京都老年人身体素质测量研究项目。没有使用假牙的部分或完全无牙合的人被排除在研究之外。预测变量包括身体状况(即年龄、性别、体重指数和握力)、口腔条件(即现有牙齿的数量、颞下颌关节噪音和假牙佩戴者)和口腔功能(即最大自愿咬合力；咬合接触面积；面颊压力；口腔动态测试/pa/，/ta/，/ka/；以及最大自愿舌压)。可变的结果是咀嚼性能。结果：握力、现有牙数、最大自发性咬合力、咬合接触面积、口腔后倾角/ka//ta/和最大自愿性舌压是影响咀嚼功能的重要因素。逐步回归分析显示，握力、最大主动咬合力和最大主动咬合力/ta/对咀嚼运动有显著影响。结论：健康老年人的咀嚼性能与握力、最大主动咬合力和最大主动咬合力/ta/密切相关。(C)2018年日本口腔修复学会。爱思唯尔有限公司出版。保留所有权利。
Purpose: Maintenance of natural dentition and/or prosthodontic rehabilitation is necessary for good masticatory function. Although other factors such as physical and oral functions are also important for masticatory performance, only a few studies have evaluated their roles. The aim of the current study was to assess factors associated with masticatory performance among elderly individuals, while maintaining and/or reconstructing all occlusal support areas.Methods: The present study was designed and implemented as a cross-sectional study, involving a total of 262 participants (mean age: 74.2 +/- 5.9 years) who participated in the Kyoto Elders Physical Fitness Measurement Research Project. Individuals with partial or complete edentulousness who did not use dentures were excluded from the study. The predictor variables included physical status (i.e., age, gender, body-mass index, and grip strength), oral conditions (i.e., number of present teeth, temporomandibular joint noise, and denture wearer), and oral functions (i.e., maximum voluntary occlusal force; occlusal contact area; cheek pressure; oral diadochokinesis test /pa/, /ta/, /ka/; and maximum voluntary tongue pressure). The variable outcome was masticatory performance. These variables among the participants using univariate and multivariate analyses were compared.Results: Grip strength, number of present teeth, maximum voluntary occlusal force, occlusal contact area, oral diadochokinesis /ka/ /ta/, and maximum voluntary tongue pressure were significant factors for masticatory performance. Stepwise regression analysis showed that grip strength, maximum voluntary occlusal force, and diadochokinesis /ta/ significantly affected masticatory performance.Conclusions: Masticatory performance was closely associated with grip strength, maximum voluntary occlusal force, and diadochokinesis /ta/ among healthy elderly participants.
