摘要
目的 确定HN-97金属烤瓷外源性着色剂的显微硬度并与Shofu stain比较。方法 用HDX-1000型显微硬度计进行测试。结果 该着色剂的显微硬度（Hv）为478.4,与Shofu stain的显微硬度（Hv）458.2相似,无显著性差异。结论HN-97金属烤瓷外源性着色剂可用于金属烤瓷修复体的外源性着色。
Objective To determine microhardness of HN-97 procelain stain and compare with Shofu stain.Methods The microhardness was tested by means of HDX-1000 model microhardnessmeter. Results The results showed that microhardness of the stain (Hv) is 478.4, wiich was similar to that of Shofu stain(Hv 458.2). No significant difference was found between both. Conclusion The stain could be used clinically for extrinsic coloration of ceramometal restoration.
