许多客观的方法已经被描述来评估咀嚼功能。最近，已经报道了一种新的口香糖系统，其利用荧光桃红-碳酸氢钠反应并测量色坐标作为功能指示剂。通过选择合适的胶基，研制出一种低粘性显色口香糖。本研究探讨了该系统的适用性和重复性的结果在不同的牙齿状态的主题。测试进行了15个自然的牙齿科目和15个全口义齿佩戴者后，确定密切相关的测试条件，通过试点研究。通过a* 测量颜色，a * 是L*a*B* 颜色系统中的坐标之一。所有受试者均可进行该测试。自然有牙组变异系数为1.87%~ 7.90%，平均为5.15%;全口义齿组变异系数为1.5%~ 17.9%，平均为9.75%。自然有齿受试者a* 的95%置信区间为28.76 +/- 1.76，全口义齿佩戴者为10.05 +/- 2.58。结果表明，该材料可用于全口义齿佩戴者和具有足够再现性的自然牙列的受试者。
Many objective methods have been described to evaluate masticatory function. Recently, a new chewing gum system has been reported that utilizes a phloxine-sodium bicarbonate reaction and measures a chromatic coordinate as a functional indicator. A low-adhesive colour-developing chewing gum has been developed by selecting an appropriate gum base. This study examined the applicability of the system and reproducibility of results in subjects with different dental states. Tests were performed on 15 natural dentate subjects and 15 complete denture wearers after determination of germane test conditions through a pilot study. The colour was measured by a*, one of the coordinates in the L*a*b* colour system. All subjects could perform the test. The coefficient of variation ranged from 1.87% to 7.90%, averaging 5.15% in the natural dentate subjects and from 1.5% to 17.9%, averaging 9.75% in the complete denture wearers. The 95% confidence interval of a* was 28.76 +/- 1.76 in the natural dentate subjects and 10.05 +/- 2.58 in the complete denture wearers. The results indicated that this material can be useful for both complete denture wearers and subjects with a natural dentition with adequate reproducibility.
