Abstract:
Objectives: To evaluate the effect of thickness and opaque resin on the light transmittance of Artglass. Methods: Samples of Artglass prepared in the thickness(mm) of 0.50,0.75,1.00,1.25,1.50,1.75 and 2.00 with or without opaque resin respectively.The light transmittance of the specimens was measured. The color values of the specimens on the CIE L*a*b* color system were determined by a digital chroma meter. Results: The light transmittance of Artglass decreased logarithmically with the increase of the thickness (R2=0.9834 in the group of samples without opaque and R2=0.9390 in those with opaque). The light transmittance of Artglass with opaque resin was lower than that without opaque resin. Conclusion: Thickness and opaque resin have significant effect on the light transmittance of Artglass.
