OBJECTIVE
To evaluate the roll of ShadeEye-NCC, a computer-aided colorimeter, in Porcelain-Fused-to-Metal crowns among patients with special colored Teeth.


METHODS
The first step was to choose the proper patients. The next was to use the colorimeter to measure the base shade of tooth and fabricate the PFM crowns according to the recipe given by the colorimeter. At last, the effects of the PFM crowns were evaluated subjectively by patients and doctor.


RESULTS
The satisfaction rates of patients and doctor were 83.7% and 81.4% respectively, there was no significant difference between the two rates.
