Abstract
The translucency of comparable shades of five dental porcelains was determined. Both direct transmittance and total transmittance were measured at wavelengths of 400-700 nm. For 1 mm of porcelain, the values for direct transmittance were low and averaged 0.13 percent, whereas the values for total transmittance averaged 26.8 percent. Transmittance increased with increasing incident wavelength. These results indicated a high degree of light scattering.
摘要
测定了五种牙科陶瓷可比色阶的半透明度。在400 - 700纳米波长下测量了直接透光率和总透光率。对于1毫米厚的陶瓷，直接透光率值较低，平均为0.13%，而总透光率值平均为26.8%。透光率随入射波长的增加而增加。这些结果表明存在高度的光散射。
