This investigation indicated that measurable declines in masticatory function due to missing teeth, with and without prosthetic replacements, alter perceptual estimates of food acceptability. Using 1,133 male participants from the Veterans Administration Dental Longitudinal Study, individuals were classified into nine dentition categories to evaluate the effect of impaired masticatory ability. The data demonstrated that when limited declines in perceived masticatory function occur, perceptual estimates of Taste Acceptability, Texture Acceptability, and Ingestion Frequency for the 13 test foods utilized are not significantly modified. In contrast, when more severe dentition losses occur, the rheological properties of each food determine the degree to which these perceptual measures, especially Perceived Ease of Chewing, will be altered. Although restorative therapy can lead to concomitant improvements in masticatory function, low perceptual responses may still be observed. These appear to be largely a function of the physical attributes of the foods ingested.
这项调查表明，无论有无假牙修复，因牙齿缺失导致的咀嚼功能可测量的下降会改变对食物可接受性的感知估计。利用退伍军人事务部牙科纵向研究中的1133名男性参与者，将个体分为九种牙列类别，以评估咀嚼能力受损的影响。数据表明，当感知咀嚼功能出现有限下降时，所使用的13种测试食物的味觉可接受性、质地可接受性和摄入频率的感知估计没有显著改变。相比之下，当发生更严重的牙列缺失时，每种食物的流变学特性决定了这些感知指标，尤其是感知咀嚼难易程度，将被改变的程度。尽管修复治疗可导致咀嚼功能随之改善，但仍可能观察到较低的感知反应。这些似乎很大程度上是所摄入食物物理属性的作用。
