The current cross-sectional investigation was undertaken to determine whether observed losses in masticatory function due to missing teeth impair perceptual estimates of food acceptability. To quantify the effect of impaired masticatory ability, 566 male participants from the Veterans Administration Dental Longitudinal Study were subdivided into three age groups (less than 40 years, 40 to 49 years, and 50 or more years) and three dentition categories (intact, partially compromised, and compromised). Bivariate analysis revealed that dentition status significantly influenced the acceptance modalities of taste, texture, perceived ease of chewing, and frequency of ingestion. Age, per se, had little effect. Significant changes in the acceptance variables were noted only in persons with compromised dentition. These findings suggested that a moderate degree of unreplaced tooth loss had no significant effect on perceptual estimates of food acceptability, and unilateral intact dentition can provide sufficient masticatory performance for maintaining food acceptance.
本次横断面调查旨在确定因缺牙导致的咀嚼功能丧失是否会影响对食物可接受性的感知评估。为了量化咀嚼能力受损的影响，来自退伍军人事务部牙科纵向研究的566名男性参与者被分为三个年龄组（小于40岁、40至49岁、50岁及以上）和三个牙列类别（完整、部分受损、受损）。双变量分析显示，牙列状况显著影响了味觉、质地、感知咀嚼难易程度和摄入频率的接受方式。年龄本身影响不大。仅在牙列受损的人群中发现接受变量有显著变化。这些发现表明，中等程度的未修复缺牙对食物可接受性的感知评估没有显著影响，单侧完整牙列可以提供足够的咀嚼性能以维持对食物的接受度。
