Standard Composite n= 1.50
...THE SOLUTIONNatural enamel n=1.62
Universal EnamelEnamel plus HRi
n= 1.62
“Glass Effect” lowers the value of the restoration with a grey halo on the margin (dark line),
due to low refractive index of composite material
The relative refractive indexes of common materials measuredat a temperature of 20°C and with a 589 nm wavelength lightindicates the deviation and speed reduction of the light that crossesa translucent area (Vanini Mangani Klimovskaia “ConservativeRestoration of Anterior Teeth” Acme 2005)
