Variables affecting the spectral transmittance of light through porcelain veneer samples.
The spectral transmittance of porcelain laminate veneers was measured at three different thicknesses (0.50, 0.75, and 1 mm) and three different opacities (25%, 75%, and 100%). The results indicated that the thickness of the porcelain veneer was the primary factor affecting light transmission and not the opacity. The measured values of transmittance were then used to estimate the setting time for light-cured luting agents of a porcelain veneer.
