Masticatory performance has often been measured by determining an individual's capacity to comminute a test food. Another method to determine masticatory performance, which is now widely used, evaluates the ability to mix and knead a food bolus. Two-coloured chewing gum and paraffin wax have been used as test foods for the quantification of the mixing ability. The aim of our study was to compare the results obtained with the comminution of an artificial test food and the results obtained from mixing of a two-coloured chewing gum. The degree of mixing of the colours of the chewing gum was quantified with an optical method. Twenty young subjects with a natural dentition (average age 24 years) and twenty elderly subjects, mostly with complete dentures (average age 72 years), participated in the study. Significant differences in masticatory performance between the two groups were detected with both methods. However, the comminution test was better in discriminating the masticatory performance of the two groups. The mixing ability test with the two-coloured chewing gum proofed to be a good method to determine masticatory function in subjects with a compromised masticatory performance (elderly subjects). However, the method appeared to be less suitable for subjects with a good masticatory performance (young subjects).
咀嚼性能通常通过确定个体粉碎测试食物的能力来衡量。另一种确定咀嚼性能的方法,即现在广泛使用的评估混合和揉捏食物团块的能力的方法。双色口香糖和石蜡已被用作测试食物,以量化混合能力。我们的研究目的是比较用人工测试食物粉碎获得的结果和用双色口香糖混合获得的结果。用光学方法定量测定口香糖颜色的混合程度。二十名具有天然牙列的年轻受试者(平均年龄 24 岁)和二十名老年人受试者(平均年龄 72 岁),大多数人都有全口义齿,参与了这项研究。两种方法都检测到两组之间咀嚼性能的显著差异。然而,粉碎测试在区分两组的咀嚼性能方面更好。双色口香糖的混合能力测试被证明是一种很好的方法,可以确定咀嚼性能受损的受试者(老年人)的咀嚼功能。然而,该方法似乎不太适合咀嚼性能良好的受试者(年轻受试者)。
