• Perceptibility of Color Differences in All-Ceramic Crowns Using Staining-Technique.

抄録

The purpose of this study was to evaluate the threshold for perceptibility of small color differences in all-ceramic crowns using staining-technique. The CIE L^*a^*b^*colorimetric system was used for the evaluation of the relationship between instrumentally measured color differences (ΔE) and human observer responsein ceramic specimens. The ceramic specimens were fabricated by staining-technique using Dicor and Empress. Twelve students, 12 young dentists with an average of2.2 years in practice and 12 veteran dentists with an average of 9.8 years in practice were used as observers. The results showed the veteran dentists were moresensitive for small color differences of ceramic specimens than the students or young dentists. Thresholds of perceptibility were 2.0 ΔE units for most subjects.
