What is it about?
The color of ninety maxillary central incisors was measured from the middle third of the labial surface with a Vita Easyshade spectrophotometer. All-ceramic crown preparations with different thicknesses (0.8, 1.2, 1.5 mm) were done on selected teeth (n = 30). Prepared teeth were randomly divided into three equal groups to fabricate ceramic crowns from three ceramic systems, Duceram LFC, In-Ceram SPINELL, and IPS Empress. Colors of cemented crowns were measured and compared with their corresponding measurements before preparations.

Why is it important?
Level of acceptance between the different ceramic materials and thicknesses varied
Perspectives
There was significant difference of ∆E between natural teeth and crowns fabricated from DLFC, ICS and IPSE ceramic materials. Also there was a significant difference of ∆E between natural teeth and 0.8, 1.2 and 1.5 mm ceramic thicknesses or combination of both.
