Rational durability of optical properties of chameleon effect of Omnichroma and Essentia composite thermocycled in black dark drinks (in vitro study)

Abstract

The color changes of the tested groups after TC are shown at Table 2 and Fig. 1. The statistical data of Omnichroma composite revealed that; Omnichroma Coff 5000 had the highest statistically significant (ΔE) value followed by Coff 2500, Cola 5000 and Cola 2500. Omnichroma DW 2500 had the least (ΔE) value which non-significant with DW 5000.
