Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Color stability assessment	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)	up to 12 months
