为了研究食物的稠度对咀嚼路径的影响，78名正常受试者被要求咀嚼煮熟的鱼酱、口香糖、花生和牛肉干。利用自动咀嚼运动分析系统对咀嚼路径、张开量和咀嚼宽度进行了研究，得到了如下结果。图案I(向工作侧平滑打开并凸合)和图案IFI(最初朝向非工作侧后向工作侧打开并凸合)构成观察到的大部分图案。在咀嚼煮鱼酱表现为模式I的那一组中，最常见的是其他三种食物中的模式I。在咀嚼煮鱼酱表现为III型的那一组中，大多数病例在其他三种食物中也都表现为DI型。随着食物硬度的增加，张口量和咀嚼宽度增加。虽然咀嚼的路径随着食物类型从软到硬的变化而不同，但在正常受试者中，大部分的咀嚼路径模式可以由模式I和模式III来表示。此外，尽管有将模式I与软食物和模式III与硬食物相关联的情况，但食物的稠度基本上不影响路径模式。
In order to investigate the effect which the consistency of the food has on the masticatory path, 78 normal subjects were asked to chew boiled fish paste, chewing gum, peanuts, and beef jerkey. The path pattern, the amount of opening, and the width of mastication were investigated using an automatic masticatory movement analyzing system, and the following results were obtained.1. The two patterns, pattern I (smooth opening toward the working side, and convex closing) and pattern ifi (opening toward working side after initially toward non-working side and convex closing) constitute the majority of the patterns observed.2. In the group which showed pattern I in chewing boiled fish paste, the most frequent case was pattern I in all other three food.3. In the group which exhibited pattern III in chewing boiled fish paste, the majority cases showed pattern DI in all other three food also.4. The amount of jaw opening and the width of mastication increased with the hardness of the food.5. It is suggested that although the path of mastication varies as the type of food changes from soft to hard, the majority of the path pattern can be represented by patterns I and III in normal subjects. Also, though there are cases which relate pattern I to soft food and pattern III to hard food, basically the consistency of the food does not affect path patterns.
