| Summary: | This study evaluated the effect of the type, opacity and thickness of the CAD/CAM lithium disilicate ceramics on the radiant power (mW), spectral radiant flux (mW/nm), the attenuation coefficient (mm-1), when using different monowave and multiwave light curing units (LCUs). Five types of A2 CAD/CAM lithium disilicate ceramic were used (n = 3): DissiliKota (Kota Imports), IPS e-max CAD (Ivoclar Vivadent), Mazic Claro CAD (Vericom), Rosetta SM (OdontoMega), and T-Lithium (Talmax); in two translucencies: high (HT) and low translucency (LT) were tested for light transmission when using three LCUs: Elipar DeepCure–L (Solventum), Quazar (FGM) and VALO Grand (Ultradent). The power (mW) and spectral radiant power (mW/nm) were measured using a fiber optic spectrometer and integrating sphere with or without the 4 different thicknesses (0.5, 1.0, 1.5, 2.0 mm) of the CAD lithium disilicate ceramics. The attenuation coefficient was measured. Data of power light were subjected to 3-way ANOVA and Tukey HSD test, percentage of light transmitted was analyzed by exponential regression (R²) (α = 0.05). Light transmission through CAD/CAM lithium disilicate ceramics was significantly influenced by the type (p<0.001), and translucency (p<0.001). LT ceramics transmitted significantly lower light than HT (p<0.001). Attenuation coefficients varied among LCUs and ceramic types, with higher values in the violet spectrum. The thickness affected significantly the percentage of light transmitted R²>0.90. CAD/CAM Lithium disilicate ceramic type, translucency, and thickness significantly affected the light transmission. As the ceramic thickness increased, there was a logarithmic decrease in light transmission, irrespective of the tested CAD/CAM lithium disilicate ceramic. Violet light was more attenuated than blue light for multiwave LCUs. Elipar DeepCure–L, Quazar, and VALO Grand exhibited similar light transmitted through all tested ceramics. |
