目的:探讨视觉比色法和电脑比色法的相关性及差异。方法:随机选取前牙固定修复病例60例,采用ShadeEye NCC电脑比色仪分别对牙冠颈1/3、中1/3、切1/3进行比色,并与Vitapan classical比色板的比色结果相比较,采用Spearman秩相关检验进行统计学分析。结果:两种比色方法在颈1/3、中1/3、切1/3相关系数分别为:0.635(P<0.01)、0.713(P<0.01)、0.392(P<0.05)。结论:两种比色法在牙冠中1/3结果相关性最好,临床应用时应合理选择并结合使用。
Objective: To explore the correlation between visual colorimetry and computer colorimetry and their differences. Methods: Sixty cases of anterior teeth were randomly selected and fixed. ShadeEye NCC computer colorimetric was used to measure the color of the crown 1/3, middle 1/3, and 1/3 of the crown, respectively, and compared with the Vitapan classical color plate Color results were compared using Spearman rank correlation test for statistical analysis. Results: The correlation coefficients of 1/3, 1/3, 1/3 of the two colorimetric methods were 0.635 (P <0.01), 0.713 (P <0.01) and 0.392 (P <0.05) respectively. Conclusion: The results of two colorimetric methods are best in 1/3 of the crowns, which should be selected and used in combination in clinical application.
