- Primary Outcome Measures
Name Time Method Color stability assessment up to 12 months VITA Easyshade® Advance spectrophotometer will be used to measure the shade on the CIELab system, which defines color on 3 axes: L\*, lightness, ranging from 0 (black) to 100 (white); and a\* and b\*, chromatic characteristics ranging from red (+a\*) to green (-a\*) and yellow (+b\*) to blue (-b\*) The color will be measured 3 times, and the mean L\*, a\*, and b\* values will be calculated and used to measure color change (delta E)
