ABSTRACT
<p><b>OBJECTIVE</b>To test ΔE between measured value and right value from the Crystaleye complete-tooth spectrophotometer, and to evaluate the accuracy rate of the spectrophotometer.</p><p><b>METHODS</b>Twenty prosthodontists participated in the study. Each of them used Vita 3D-Master shadeguide to do the shade matching, and used Crystaleye complete-tooth spectrophotometer (before and after the test training) tested the middle of eight fixed tabs from shadeguide in the dark box. The results of shade matching and spectrophotometer were recorded. The accuracy rate of shade matching and the spectrophotometer before and after training were calculated.</p><p><b>RESULTS</b>The average accuracy rate of shade matching was 49%. The average accuracy rate of the spectrophotometer before and after training was 83% and 99%.</p><p><b>CONCLUSIONS</b>The accuracy of the spectrophotometer was significant higher than that in shade matching, and training can improve the accuracy rate.</p>
