Abstract

This study of the fluorescence of natural enamel and of dental ceramics shows the fluorescence of ceramics not containing rare earths decreases when the color saturation increases; the fluorescence of samples of the same shade guide are not homogenous; some guides show a strong green fluorescence; and two shade guides of the same origin can present completely different fluorescence. The cementing medium can affect the fluorescence of a ceramic prosthesis.

摘要

这项关于天然牙釉质和牙科陶瓷荧光的研究表明，不含稀土元素的陶瓷的荧光会随着颜色饱和度的增加而降低；同一比色板样本的荧光并不均匀；一些比色板显示出强烈的绿色荧光；并且两个相同产地的比色板可能呈现出完全不同的荧光。粘结介质会影响陶瓷假体的荧光。
