抄録

The difference in color tone between adhesive resin cement used for bonding of all-ceramic restorations and trial cement used for trial, as well as the influence on color tone of restorations when the cement was present were studied. Further, using these data, it was attempted to assess the validity of the value of 2.0, which has been used as the reference for the color difference (ΔE<SUP>*</SUP>ab) heretofore.<BR>The conclusions were as follows:<BR>1. It was only the specimen of Opaque White which showed a color difference (ΔE*ab) of 2.0 or less in the value of L<SUP>*</SUP>a<SUP>*</SUP>b<SUP>*</SUP> between adhesive resin cement and trial cement. As for the other types of cement, the value was as high as 2.81 to 5.34, showing that color tones were different.<BR>2. Color difference (ΔE*ab) of the value of L<SUP>*</SUP>a<SUP>*</SUP>b<SUP>*</SUP> of the combined specimen of abutment, cement, and ceramic showed a value of 2.0 or lower in all combinations.<BR>3. As the result of a visual comparison test, in case of translucent ceramic, it was found that the use of the value of 2.0 as the reference (criterion) for color difference (ΔE<SUP>*</SUP>ab) was appropriate.
