The effect of the immersion durations on the color stability of composite resins were detected by calculating the color changes (the differences between initial and after immersion measurements) using the formula:16 Δ��� ������������ �� ��Δ�������� ������������ �� ��Δ�����Δ�����L*)2 + �Δ �����Δ ����� a*)2 + �Δ�����Δ�����b*)2 ]½ Notes: E* = color change L* = Brightness a* = amount of red (positive values) and green (negative value) b* = amount of yellow positive value) and blue ( negative value)	cache/mkg-949.pdf	txt/mkg-949.txt
