The aim of the study is to evaluate the effect of extrinsic pigmentation on the dimensional stability, hardness, detail reproduction, and color of a silicone after thermocycling.


 Readings for the tests were taken before and after thermocycling (2,000 cycles).  For the dimensional stability test, comparing the initial time with the final time, there was a significant contraction in both groups after thermocycling.  For the hardness test, comparing the time points, only group 1 showed a significant reduction in hardness after thermocycling.  Groups 1 and 2 scored 2 for the detail reproduction test, before and after thermocycling.
