摘要： 目的 了解临床常用牙龈瓷的颜色参数。方法 采用分光光度法分别测量Shofu VINTAGE和Vita VMK95 牙龈瓷在黑、白背景下的色度学参数。结果 黑、白背景会造成牙龈瓷颜色的明显改变。常用牙龈瓷的颜色空间 是L*:41·85~50·64,a*:12·46~19·46,b*:1·33~4·62。结论 常用牙龈瓷的颜色空间尚不能完全覆盖天然牙龈 的色域空间。

Abstract:
Objective To study the distribution of the chromatic value of gingival porcelains.Methods The color change of Shofu VINTAGE and Vita VMK95 gingival porcelains on the black and white backings was determined with a spectrophotometer (PR-650).Results The results showed that the chromatic value of gingival porcelains was different on varying backings. The color space of gingival porcelain was L*: 41·85~50·64, a*: 12·46~19·46, b*: 1·33~4·62.Conclusion The chromatic value distribution cannot cover the color region of natural gingiva.
