Crystaleye 计算机比色仪联合数码摄影在上颌前牙比色中的效果

摘要：目的探讨Crystaleye 计算机比色仪以及Crystaleye 计算机比色仪联合数码摄影在上颌前牙修复体比色中应用的效果。方法随机选择临床上需上颌前牙金铂烤瓷单冠修复的患者共43 例，制作43 颗修复体，将患者随机分为3 组，A 组采用肉眼人工比色板比色，B 组采用Crystaleye 计算机比色仪比色，C 组采用Crystaleye 计算机比色仪联合数码摄影比色。修复后由患者和一名工作5 年以上的主治医师用视觉模拟评分（VAS）法对修复体颜色满意度分别进行评价。3 组修复体粘接完毕后，由同一名护士用计算机比色仪对修复体及其对侧同名牙比色，分别记录ΔE值。用SPSS 13.0 统计软件对结果进行单因素方差分析。结果对患者而言，A 组和B 组无统计学意义（P>0.05），A 组和C 组差异具有统计学意义（P

Abstract:Objective The purpose of this study was to evaluate the effect of Crystaleye computer spectrophotometer and it combined with digital camera in anterior upper tooth color shading. Methods 43 patients in need of an up anterior tooth restoration with noble metal -ceramic crown were enrolled in this study randomly. They were divided into three groups randomly. Group A used the conventional visual shade matching method. Group B used Crystaleye computer spectrophotometer system. Group C used Crystaleye computer spectrophotometer combined with digital camera method. The crown was evaluated by patients and a dentist respectively using visual analogue scale（VAS） method. After restoration, Crystaleye was used to catch the ΔE value between the crown and the opposite side tooth. The results were compared using one -way ANOVA respectively. Results For patients, there were no significant differences between group A and group B（P>0.05）. While there were significant differences between group A and group C（P
