背景：VITA 3D Master比色板是近年来新推出的新型比色系统，具有广泛的应用前景。目的：评价牙本质比色对铸瓷修复体临床精确比色的意义。<br> 方法：分别使用常规比色法和常规比色法联合牙本质比色法(联合比色法)为30例患者的患牙颈1/3、中1/3、切1/3进行比色。在CIE1976L*a*b*色度系统下，用单反数码相机(Canon D50)对2种比色方法制作的铸瓷修复体与同名牙进行色度值测定和分析。并对各种新型比色方法进行举例分析。<br> 结果与结论：常规比色法制作的修复体△L*为1.22±0.16，△C*为1.19±0.20，△H*为0.31±0.05，△E*为1.32±0.13；联合比色法制作的修复体△L*为1.03±0.11，△C*为1.12±0.19，△H*为0.29±0.03，△E*为1.23±0.11。常规比色法制作的修复体满意22例，联合比色法制作的修复体满意23例。患者对2组修复体色彩还原效果满意度差异无显著性学意义(P>0.05)，2组修复体色差分析有统计学意义(P<0.05)。
揹景：VITA 3D Master比色闆是近年來新推齣的新型比色繫統，具有廣汎的應用前景。目的：評價牙本質比色對鑄瓷脩複體臨床精確比色的意義。<br> 方法：分彆使用常規比色法和常規比色法聯閤牙本質比色法(聯閤比色法)為30例患者的患牙頸1/3、中1/3、切1/3進行比色。在CIE1976L*a*b*色度繫統下，用單反數碼相機(Canon D50)對2種比色方法製作的鑄瓷脩複體與同名牙進行色度值測定和分析。併對各種新型比色方法進行舉例分析。<br> 結果與結論：常規比色法製作的脩複體△L*為1.22±0.16，△C*為1.19±0.20，△H*為0.31±0.05，△E*為1.32±0.13；聯閤比色法製作的脩複體△L*為1.03±0.11，△C*為1.12±0.19，△H*為0.29±0.03，△E*為1.23±0.11。常規比色法製作的脩複體滿意22例，聯閤比色法製作的脩複體滿意23例。患者對2組脩複體色綵還原效果滿意度差異無顯著性學意義(P>0.05)，2組脩複體色差分析有統計學意義(P<0.05)。

BACKGROUND:VITA 3D Master shade guide is a newly launched colorimetric system in recent years, with a wide clinical prospect. <br> OBJECTIVE:To evaluate the significance of dentin colorimetric evaluation for accurate color section of cast ceramic prostheses. <br> METHODS:Using conventional colorimetric assay and conventional colorimetric assay combined with dentin colorimetric assay (combined colorimetric assay), 30 patients were subject to colorimetric evaluation 1/3 to the neck, central part, and cut end of the tooth. In CIE1976L*a*b*color system, a digital SLR camera (Canon D50) was used for colorimetric measurement and analysis of cast ceramic prostheses prepared with two colorimetric methods and teeth with the same name. And a variety of new colorimetric methods were analyzed based on examples. <br> RESULTS AND CONCLUSION:In the conventional colorimetric group,△L*was 1.22±0.16,△C*was 1.19±0.20,△H*was 0.31±0.05,△E*was 1.32±0.13. in the combined colorimetric group,△L*was 1.03±0.11,△C*was 1.12±0.19,△H*was 0.29±0.03,△E*was 1.23±0.11. Cast ceramic prostheses prepared by conventional colorimetric method were satisfactory in 22 cases, while cast ceramic prostheses prepared by the combined colorimetric method were satisfactory in 23 cases. There was no difference in patient satisfaction for color rendition (P>0.05), but chromatic difference analysis was significantly different between the two groups (P<0.05).
