To show relationships between oral conditions and physical performance in the elderly living independently.
A total of 821 persons participated. Data on background factors and self-assessed masticatory ability were collected by means of questionnaires. An intraoral examination was performed to examine the pattern of occluding pairs of natural teeth. Handgrip strength and one-leg standing time with eyes open were measured. Step-wise linear regression models were conducted with muscle strength or one-leg standing time as the dependent variables; the pattern of occluding pairs and self-assessed masticatory ability as the principal independent variables.
The self-assessed masticatory ability was retained in the final model of the step-wise regression for the handgrip strength, and significant relationships were established in the participants aged 65-74, but the pattern of occluding pairs was not retained. The pattern of occluding pairs, and the self-assessed masticatory ability were retained in the final models for the one-leg standing time, and significant relationships were shown here.
The self-assessed masticatory ability may be significantly related to muscle strength and static balance function, and the pattern of occluding pairs may be significantly related to the static balance function, particularly in the elderly aged 65-74.
展示独立生活的老年人的口腔状况与身体机能之间的关系。
共有 821 人参与。通过问卷调查收集背景因素和自我评估的咀嚼能力数据。进行口腔检查以检查天然牙咬合对的模式。测量握力和单腿睁眼站立时间。逐步线性回归模型以肌肉力量或单腿站立时间作为因变量；咬合对的模式和自我评估的咀嚼能力作为主要自变量。
自我评估的咀嚼能力保留在握力逐步回归的最终模型中，在 65-74 岁的参与者中建立了显著关系，但咬合对的模式没有保留。咬合对的模式和自我评估的咀嚼能力保留在单腿站立时间的最终模型中，并且显示出显著关系。
自我评估的咀嚼能力可能与肌肉力量和静态平衡功能显著相关，而咬合对的模式可能与静态平衡功能显著相关，特别是在 65-74 岁的老年人中。
