The objective of this study was to confirm the validity of a Self-Implementable method to evaluate masticatory performance using a newly developed color scale and color-changeable chewing gum.
We developed a dedicated color scale that enables anyone to easily check the color of the chewing gum instead of using specialist equipment. To examine the reliability of evaluating the masticatory performance by the subjects themselves, three groups of six subjects were recruited: a group of dentists, a group of adults and a group of elderly adults were asked to check the colors of the chewed samples using the color scale. The correlation between the use of the color scale and the use of a colorimeter to determine the color of the chewing gum was studied to confirm the validity of the color scale. To assess the reliability, intraclass correlation coefficients (ICCs) were determined.
A strong correlation was found between the a* value measured by the colorimeter and the mean scores from the color scale. The ICCs for intra-examiner and inter-examiner consistency were more than 0.88 for all three groups.
This research confirmed the validity and reliability of colorimetric analysis of color-changeable chewing gum using a color scale as a Self-Implementable method of evaluating masticatory performance.
本研究旨在确认一种使用新开发的变色口香糖和自我实施方法评估咀嚼性能的有效性。
我们开发了一种专用的色标，使任何人都可以轻松检查口香糖的颜色，而无需使用专业设备。为了检验受试者自身评估咀嚼性能的可靠性，招募了三组 6 名受试者：一组牙医、一组成年人和一组老年人，要求他们使用色标检查咀嚼样本的颜色。研究了使用色标和颜色计确定口香糖颜色之间的相关性，以确认色标的有效性。为了评估可靠性，确定了组内相关系数（ICC）。
颜色计测量的 a*值与色标平均得分之间存在很强的相关性。三组的组内和组间一致性 ICC 均大于 0.88。
本研究证实了使用色标对变色口香糖进行比色分析作为评估咀嚼性能的自我实施方法的有效性和可靠性。
