ABSTRACT
Objective:
To find out the infinity optical thickness of SY-1 silicone elastomers when color difference(△E) is equal to 1.5 .Methods:
Silicone elastomer samples with thickness from 0.5 mm to 10 mm of SY-1 silicone elastomer were measured by CIE-1976-L *a *b * relative to CIE source against a white and a black background by using Minolta colorimeter . Color difference was calculated as △E=[(△L *) 2+( △a *) 2+(△b *) 2] 1/2 . The infinity optical thickness of SY-1 silicone elastomer when △E=1.5 was calculated by regression formulation.Result:
When △E was equal to 1.5, the infinity optical thickness of SY-1 silicone elastomer was 7.60 mm.Conclusion:
In order to get ideal effect the supports should be treated with colorant when the thickness of silicone elastomer covering the surface of supports in maxillofacial prostheses is thinner than 7.60 mm.
