摘要：

目的对标准化比色环境中口腔医学生在D55和D65光源条件下的比色结果进行比较。方法随机抽取市售Vitapan 3D-Master比色板2套,其中一套作为比色板,从另一套比色板中选出来10个比色片,分别为2L2.5、2M2、2R2.5、3M2、3R2.5、3L1.5、3R1.5、3L2.5、4R1.5、4L1.5色片,用胶布遮盖比色片下字标,用阿拉伯数字标记1~10号。对49名口腔医学生进行比色方法的培训后,要求其抽取10个色片中的任意两个色片,在D65以及D55日光灯下对所抽取的色片比色,分别计算2种光源下每位参与者选择的颜色和牙面实际颜色的平均色差值ΔE,并进行统计学分析。结果在D55光源下每位参与者选择的牙片颜色与牙片实际颜色的ΔE范围为0~6.540,平均为2.501;在D65光源下,每位参与者选择的牙片颜色与牙片实际颜色的ΔE范围为0~6.610,平均为2.530。二者差异无统计学意义（P=0.921）。结论 D55和D65日光灯均可以用于日常的牙科比色,2种不同的色温下比色结果无明显差异。

Abstract:

Objective This study aimed to compare the effect of D55 and D65 light sources on the visual colorimetry performance of dental students by using a homemade light-source shelf. Methods Two Vitapan 3D-Master shade guides were randomly selected. One set was used as shade guides. Ten commonly used shade tabs of 2L2.5, 2M2, 2R2.5, 3M2, 3R2.5, 3L1.5, 3R1.5, 3L2.5, 4R1.5, and 4L1.5 were selected from the other set with covered value marks and numbered from 1 to 10. After the colorimetric training, 49 undergraduate dental students were randomly divided into two groups. Each student randomly selected two of the 10 shade tabs, and the colors were subsequently matched under D65 and D55 light sources from a distance of approximately 40 cm. The average color difference (ΔE) between the color selected by each participant and the actual color of shade tabs was calculated. Paired t test was used for statistical analysis. Results The ΔE values between the color selected by each participant and the actual color of the shade tabs under the D55 light source varied from 0 to 6.540. The average value was 2.501. The ΔE values between the color selected by each participant and the actual color of the shade tabs under the D65 light source varied from 0 to 6.610. The average value was 2.530. No statistically significant difference was observed between the results under the two light sources (P=0.921). Conclusion Both D55 and D65 daylight lamps can be used for daily dental colorimetry. These two different color temperatures showed no significant difference.
