Abstract
Purpose: The purpose of this in vitro study was to evaluation the effect of shade on all ceramic restoration based zirconia according to cooling rate on Firing.
Methods: 10 specimens applied to the dentin porcelain were made on the zirconia. After 5 specimens of the first group were burned in the furnace, these were put out rapidly. And after 5 specimens of the second group were burned in the furnace, these were put out slowly later 15 min. All specimens were measured L*, a*, b* using spectrophotometer, there were calculated 10 mean(SD) of descriptive statistics with SPSS program. These data were used for ΔE* with color difference equation. Independent t tests were performed between 2 groups.
Results: L*, a*, b* of 2 groups was statistically significant respectively (p<0.001), ΔE* was 4.55 value.
Conclusion: This study showed effect of shade on all ceramic restoration based zirconia according to cooling rate on Firing.
