以前的研究已经确定了与咀嚼性能相关的各种因素。本研究旨在调查日本一般城市人口中不同咬合支撑区的咀嚼效能相关因素之差异及影响。Suita研究共纳入1875名日本受试者(平均年龄：667岁)。使用社区牙周指数(CPI)评估牙周状况。记录功能牙数和咬合支持面积(OSA)，根据Eichner指数将牙合支持面积分为完全、减少和消失三类。咀嚼性能通过测试胶状凝胶的方法进行测定。对于义齿佩戴者，在义齿到位的情况下测量咀嚼性能。多元线性回归分析显示，在控制其他变量的情况下，完美OSA患者的咀嚼性能与性别、功能牙数量、最大咬合力和牙周状况显著相关。在OSA降低的情况下，咀嚼性能与功能牙数、最大咬合力和牙周状况显著相关。在丧失的OSA中，咀嚼能力与最大咬合力显著相关。最大咬合力是一个显著影响咀嚼性能的因素，这在所有OSA组中都是常见的。在控制了可能的混杂因素后，OSA完善组和OSA降低组的功能牙数和牙周状况是共同的因素，在OSA完善组中只有性别有显著意义。这些发现可能有助于为患有牙齿缺失或牙周病的老年人提供饮食指导。
Previous studies have identified various factors related to masticatory performance. This study was aimed to investigate variations and impacts of factors related to masticatory performance among different occlusal support areas in general urban population in Japan. A total of 1875 Japanese subjects (mean age: 667 years) were included in the Suita study. Periodontal status was evaluated using the Community Periodontal Index (CPI). The number of functional teeth and occlusal support areas (OSA) were recorded, and the latter divided into three categories of perfect, decreased and lost OSA based on the Eichner Index. Masticatory performance was determined by means of test gummy jelly. For denture wearers, masticatory performance was measured with the dentures in place. The multiple linear regression analysis showed that, when controlling for other variables, masticatory performance was significantly associated with sex, number of functional teeth, maximum bite force and periodontal status in perfect OSA. Masticatory performance was significantly associated with number of functional teeth, maximum bite force and periodontal status in decreased OSA. In lost OSA, masticatory performance was significantly associated with maximum bite force. Maximum bite force was a factor significantly influencing masticatory performance that was common to all OSA groups. After controlling for possible confounding factors, the number of functional teeth and periodontal status were common factors in the perfect and decreased OSA groups, and only sex was significant in the perfect OSA group. These findings may help in providing dietary guidance to elderly people with tooth loss or periodontal disease.
