Abstract:
OBJECTIVETo analyze the final color of Solidex in six thickness interacting with three different backgrounds.
METHODSFive specimens of Solidex in each shade A1, A3, and C2 were fabricated at thickness of 1.0, 1.2, 1.4, 1.6, 1.8, and 2.0 mm. The CIE L(*)a(*)b(*) values of specimens were measured using a colorimeter (ShadeEye NCC) to determine the colorimetric difference, when the specimens overlaid on different backgrounds.
RESULTSWhen the thickness was more than 1.8 mm, the color difference (DeltaE(*)ab < 1) was not perceived by human observers. When the thickness was 1.4 mm or less than 1.4 mm, the color difference (DeltaE(*)ab > 2.72) was considered clinically unacceptable between alloy background and two types of composite resin background.
CONCLUSIONSAlloy background had more evident influence on the final color of Solidex than composite resin background. When making metal-free crown restoration using Solidex, it was advisable to make the composite resin more than 1.8 mm thick.
