Abstract
The following conclusions were drawn from this study. 1. The L* value in all experimental group was lesser than in control group. 2. The a* value was increased in most experimental group, but those of MDX4-4210 materials pigmented with Raw sinna and with Mars violet in group 3,4,5 were decreased. 3. The b* value in group 1,2,3 was decreased, but that in group 4,5 was increased. There was no statistical difference between control and most of group 3.4.5. 4. The deltaE* value was decreased in all experimental group except A-2186 material in group 4, and the changes of deltaE* value of MDX4-4210 materials pigmented with Red yellow and with Mars violet were great(over than 2.0). 5. The total amount of change of L* and a* value were greater in A-2186 silicone, but that of deltaE* was greater in MDX4-4210 silicone. 6. The total amount of change of L* value was greater in experimental group 4, that of a* was greater in group 1, and those of b* and deltaE* values were greater in group 2.
