摘要:

目的    评价分光光度计型全牙比色仪Olympus Crystaleye临床比色的可重复性。方法    于2009年9—10月,使用分光光度计型全牙比色仪Olympus Crystaleye测试10名志愿者健康的左上颌中切牙中1/3色彩学参数,每个测试对象测色10次,分别记录其 [L   a   b   ]   值(CIE1976 [L   a   b   ]   ),并计算[L   a   b   ]   平均值。次日用相同方法再次测量并记录,同一测试对象再次测量结果与前次计算的[L   a   b   ]   平均值进行比较,计算平均色差值  2-1,评价比色仪的可重复性。结果      2-1值范围为0.32~0.66。结论    使用分光光度计型全牙比色仪Olympus Crystaleye进行临床比色,有较高的可重复性。

Abstract:

Objective   To evaluate the repeatability of a spectrophotometer shade-mactching device,Olympus Crystaleye. Methods   Ten volunteers were chosen for this trial. A new dental spectrophotometer shade-mactching device Olympus Crystaleye was used to measure the left maxillary central incisor of each object for 10 times. The color parameters (CIE1976 [L   a   b   ]   ) of central 1/3 body area of each tooth were recorded.Then,the [L   a   b   ]   *average chroma values were calculated. The next day,the same test was repeated,and the results of the same object was compared with the average [L   a   b   ]    value before,then each   2-1 was calculated. Results     2-1 ranged between 0.32 ~ 0.66. Conclusion   The repeatability of Olympus Crystaleye colorimeter could be accepted in clinical shade-matching.
