Table 4: Shade and color stability

 

Comment: Three products claim color stability, but one of them did not comply with the requirement. The other products were also tested even though they did not claim any color stability.

 

Comparison with VITA-shade guide unless otherwise noted.

      Shade guide not nominated
(A)     The color of the wet specimen has a close match compared with the shade guide
(B)     The wet specimen is evenly pigmented
(C)     Color difference between wet and dry specimen
(D)     Color difference between irradiated and not irradiated parts of the specimen
(E)     Color difference between the irradiated part of the wet specimen compared with a dry specimen
(F)     Color difference between the not irradiated part of the wet specimen compared with a dry specimen

Requirements in ISO 4049:

(A) and (B):                            Yes
(C), (D), (E) and (F):              None or slight (only if the manufacturer claims color stability)
