本研究的目的是探讨客观咀嚼功能（咀嚼性能和食物混合能力）、患者咀嚼能力感知和口腔健康相关生活质量（OHRQoL）之间的关系。部分有牙的可摘局部义齿患者131例，平均年龄67岁。进行客观、主观咀嚼功能和OHRQoL四项测试。以花生或双色蜡块为试验对象，评价咀嚼性能和食物混合能力。通过食物摄入问卷对患者的咀嚼能力进行评估。OHRQoL使用日语版的口腔健康影响概况进行测量。在假设客观咀嚼功能以感知咀嚼能力为中介因素与OHRQoL相关的基础上，构建结构方程模型。结构方程模型分析发现，感知咀嚼能力对OHRQoL的中等影响有统计学意义，咀嚼性能对感知咀嚼能力和OHRQoL的中等或小影响有统计学意义（P < 0中心点05）；而食物混合能力对感知咀嚼能力和OHRQoL的影响无统计学意义（P >0 0中心点05）。拟合指数表明模型与数据拟合良好（拟合优度指数= 0中心点99）。上述结果提示，咀嚼感知能力是影响口腔整体生存质量的关键因素，咀嚼功能对口腔整体生存质量的影响比食物混合能力更重要。
P>The aim of this study was to investigate the relationships between objective masticatory function with respect to masticatory performance and food mixing ability, patients' perception of chewing ability and oral health-related quality of life (OHRQoL). Partially dentate patients with removable partial dentures (n = 131, mean age 67 center dot 1 year) participated in the study. Four tests were performed to evaluate objective and subjective masticatory function and OHRQoL. Masticatory performance and food mixing ability were assessed using peanuts or a two-coloured wax cube as test items. Patients' perception of chewing ability was rated using a food intake questionnaire. OHRQoL was measured using the Japanese version of the oral health impact profile. A structural equation model was constructed based on hypothesis in which objective masticatory function would be related to OHRQoL via perceived chewing ability as a mediator. Structural equation modelling analysis found a statistically significant medium effect of perceived chewing ability on OHRQoL and statistically significant medium or small effects of masticatory performance on perceived chewing ability and OHRQoL (P < 0 center dot 05); however, the effect of food mixing ability on perceived chewing ability or OHRQoL was not statistically significant (P > 0 center dot 05). A fit index indicated that the model fitted well to the data (Goodness-of-fit index = 0 center dot 99). These results suggest that perceived chewing ability is a critical factor for OHRQoL and that masticatory performance rather than food mixing ability is important for perceived chewing ability and OHRQoL in patients with removable partial dentures.
