ABSTRACT
STATEMENT OF PROBLEM:
The color change of final restoration resulting from resin cement is variable since the amount of the tooth is prepared is minimum.PURPOSE:
The purpose of this study was to compare the color accuracy of try-in paste and their corresponding resin cements and the color stability of restoration intermediated resin cement according to two shades of three products(Rely-X, Variolink II, Choice). MATERIAL ANDMETHOD:
Color was measured for porcelain disk sample without try-in paste, and porcelain disk sample intermediated by try-in paste and resin cement, then color differences were calculated.RESULTS:
1. Color difference(delta E*) between try-in paste and resin cement showed the lowest value at Variolink II and increased in the order Choice and Rely-X statistically significant, and delta E* of three resin cements was greater in A3 then A1. 2. The values of delta L* and delta a* between try-in paste and resin cement was in the increasing order of Variolink II, Choice and Rely-X. The delta b* value was increased in this order Choice, Rely-X and Variolink II in A1, on the other hand Variolink II, Rely-X and Choice in A3. 3. Color difference(delta E*) before and after resin cement showed the lowest value at Variolink II and increased in the order Rely-X and Choice.CONCLUSION:
Above result revealed that the colors of try-in paste and resin cement were more or less accurate in the range of 0.35-1.95 of color difference which was unnoticeable with human eye, and Variolink II was superior to the other resin cements in color accuracy.
