在颌面修复的配色过程中，不同的测色系统所提供的颜色信息是不同的。我们研究的假设，一个非接触式测量系统和4个接触式测色仪器进行测量的准确性和精密度的色素颌面部弹性体标本具有人类肤色。在第一阶段，对不透明标准色标的准确度进行了测量比较。在第二阶段，具有最佳准确度的系统被用作参考仪器，并在弹性体样本上进行准确度和精密度的比较。采用CIEDE2000色差公式。对CIELAB和仪器之间的色差进行重复测量ANOVA和Tukey检验和线性回归分析。接触式测量系统在精度上表现不同，可能是由于边缘损失和其他因素，但与非接触式测量仪器在精度上表现相同。这种非接触式系统推荐用于颌面修复材料的颜色测量。
Color information from different color-measuring systems varies during color matching in maxillofacial prosthetics. We studied the hypothesis that a non-contact measuring system and 4 contact color-measuring instruments perform comparably in accuracy and precision on measurements of pigmented maxillofacial elastomer specimens having human skin colors. Measurement comparisons in accuracy on opaque standard color patches were made in Phase I. In Phase II, the system with the best accuracy was used as the reference instrument, and comparisons in accuracy and precision on elastomer specimens were made. The CIEDE2000 color difference formula was used. Repeated-measures ANOVA with Tukey testing and linear regression analysis for CIELAB and color differences among the instruments were performed. The contact measuring systems perform differently in accuracy, possibly due to edge loss and other factors, but performed comparably in precision with the non-contact measuring instrument. This non-contact system is recommended for color measurement of maxillofacial prosthetic materials.
