Reference CAD-CAM Samples for Dental Shade Communication for Successful Aesthetic Outcome

When comparing CAD/CAM samples and VC shade tabs, visible and measurable color differences (ΔE00 > AT50:50%) were found in the case of all ZrO2 samples and in three out of five evaluated shades of ZLS samples. The color consistency of the blocks was acceptable. Better shade communication and more reliable shade reproduction is achieved when reference photos are sent with a color sample made from the restoration material.
