摘要：

背景：研究表明，使用乳光效果釉质瓷粉对氧化铝全瓷冠美观效果有一定程度的影响。
目的：观察使用乳光效果釉质瓷粉对氧化铝全瓷冠颜色效果的影响。
方法：使用乳光效果釉质瓷粉、普通釉质瓷粉分别制作瓷层厚度2.0 mm的氧化铝全瓷冠试件样本20个。以比色片A2色为对照试件由专业口腔技师大体观察色差；大体观察结束，取唇面部分制作成圆盘试件采用PR650分光光谱测色仪对圆盘试件测色，测量透射率、明度、色相、彩度值并计算色差，分析其颜色变化。
结果与结论：大体观察实验组满意度80%，对照组满意度50%；使用乳光效果釉质瓷粉的全瓷冠与比色片之间色差差异存在显著性意义(P < 0.05)，透射率差异无显著性意义(P > 0.05)；两两比较明度值差异有显著性意义(P < 0.05)，实验组值最高；色相值对照组>比色片>实验组偏红色，差异无显著性意义(P > 0.05)；彩度值实验组>对照组>比色片偏蓝色，差异无显著性意义(P > 0.05)，提示使用乳光效果釉质瓷粉可减小氧化铝全瓷冠与比色片颜色的色差但不能明显提高其半透性。

Abstract:

BACKGROUND: Studies have proved that opalescent porcelain enamel powder has some effect on aesthetic effect of alumina all-ceramic crowns.
OBJECTIVE: To observe the effect of opalescent porcelain enamel powder on the chrominance of alumina all-ceramic crowns.
METHODS: Ten samples of alumina ceramic crowns with opalescent porcelain enamel powder, and 10 samples with ordinary porcelain enamel were prepared. The ceramic layer thickness of all samples was 2.0 mm. Then PR650 spectrophotometer color measurement instrument was used to measure chrominance of these samples with shade tabs color A2 regarded as the control color, including transmissivity, luminosity, hue of color, chroma. The chromatic aberration was calculated and their color changes were analyzed.
RESULTS AND CONCLUSION: The satisfaction degree was 80% for the opalescent porcelain enamel powder, and 50% for the ordinary porcelain enamel. There were significantly differences in the chromatic aberration between the all-ceramic crowns of opalescent porcelain enamel powder and the shade tabs (P < 0.05). No significant difference was found in transmissivity T (P > 0.05). The luminosity showed significant differences among the three groups, which was highest in the opalescent porcelain enamel powder group (P < 0.05). The hue of color was arranged as follows: the ordinary porcelain enamel group > the shade tabs > the opalescent porcelain enamel powder group, and there was no significant difference (P > 0.05). The chroma values were ranked as follows: the opalescent porcelain enamel powder group > the ordinary porcelain enamel group > the shade tabs, and there was no significant difference (P > 0.05). The opalescent enamel porcelain powder can decrease chromatic aberration between alumina all-ceramic crowns and shade tabs, but cannot improve their semipermeability significantly.
