Comparison between the theoretically-predicted and experimentally-measured in-line transmission values for nanocrystalline 3Y-TZP as a function of wavelength. The 3Y-TZP examined have a common mean grain size d = 80 nm and thickness t = 1 mm. An average birefringence Δn_ave = 0.020 – 0.033 was used in theoretical prediction, whereas the experimental data was obtained from ref. [21]. Regions bounded by two dashed lines were extrapolations of the theoretical prediction, due to the violation of the criterion for Rayleigh scattering. Again, the dashed horizontal line at T_IT = 2.5% represents a measured average in-line transmission value of various dental porcelains with a common thickness 1 mm at a wavelength of 555 nm.
