Repeatability and Accuracy of A New Dental Spectrophotometer Shade-matching Device Olympus Crystaleye
摘要
Abstract
Objective To evaluate the repeatability and accuracy of a new dental spectrophotometer shade-matching device, Olympus Crystaleye. Methods Al, 1M1 shade guide, one isolated left central incisor fixed in the blinded-box, and one left central incisor from a volunteer were included in this experiment. Olympus Crystaleye was used to measure them with repeating of twenty times. The color parameters(CIE1976 L' a' b' )of incisal, body and cervical of each sample were recorded. The next day, the same test was repeated, and the results of the same object was compared with the average L' a' 6* value before, each A￡was calculated. Then the 120 different areas color records of Al, 1M1 shade guide were tested forty times and compared to the standard value. The matching rates of correct shade were calculated, and the two rates were compared with chi-square test. Results In the four groups, the A ￡ ranged between 0.45- 0.82, all less than 1.70. The matching rate of correct shade in Al was 95.85% , whereas 97. 50% was obtained in 1M1. Conclusion The repeatability and accuracy of Olympus Crystaleye colorimeter could be acceptable clinically.关键词
