Abstract

Objectives: This study evaluated the impact of blinding shade guide tabs on the accuracy of colour selection and the preference for shades in the A hue category.

Methods: Disc-shaped specimens were created in 8 shades: 4 in the A hue (A1, A2, A3, A4) and 4 in different hues (B1, B2, C2, D3). Using both blinded and unblinded guides, 15 dental students and 15 experienced dentists evaluated the specimens' shades. Colour accuracy was assessed using the overall colour difference (ΔE00) and individual colour coordinates (CIELCH system) between the selected shade tab and the actual specimen. The percentage of selections favouring the A hue was also calculated.

Results: Blinding the shade guide tabs did not significantly impact the accuracy of colour selection. However, unblinded evaluations resulted in a higher percentage of selections favouring the A hue (44%) compared with blinded evaluations (34%). No significant difference was found between the evaluations of dental students and experienced dentists.

Conclusion: Blinding shade guide tabs did not affect the precision of colour selection but reduced the tendency to choose shades in the A hue category.

致盲阴影指南对牙科实践中颜色选择和色调偏好精度的影响。

目的：本研究评估了盲色度指南标签对颜色选择准确性的影响，以及对A色度类别中色度的偏好。方法：制作8种颜色的圆盘状标本：A色调4种（A1、A2、A3、A4），不同色调4种（B1、B2、C2、D3）。15名牙科学生和15名经验丰富的牙医使用盲法和非盲法指导来评估标本的阴影。使用所选色度标签和实际样品之间的整体色差（ΔE00）和单个颜色坐标（CIELCH系统）来评估颜色准确性。还计算了选择A色调的百分比。结果：遮光导色卡对颜色选择的准确性没有显著影响。然而，与盲法评估（34%）相比，非盲法评估导致选择a色调的比例更高（44%）。牙科学生和有经验的牙医的评价没有显著差异。结论：遮光色度指导标签不影响颜色选择的精度，但降低了选择A色度类别色度的倾向。
