Abstract

PURPOSE
The aim of this study was to compare the translucency of two different laminate ceramic veneers with and without glazing.
MATERIALS AND METHODS
Ten millimeter side square-shaped specimens in 0.3 mm and 0.6 mm thick were fabricated for the following materials with and without glazing (n=80): A1 shade IPS e.maxPress (IEM) and Styleveneers (STV). The color coordinates (CIE L* a* b*) of the specimens were measured with a colorimeter. The Translucency parameter (TP) was calculated from the color difference of the material on a black versus a white background. For comparisons between materials and between the' not glazed'and' glazed'groups, unpaired t-test was used to analyze the data (P=.05).
RESULTS
The TP (Mean +/- SD) of' not-glazed'and' glazed'group of IEM specimens at 0.3 mm thickness were 45.99 +/- 3.00 and 49.53 +/- 2.28 and the TP at 0.6 mm thickness were 32.82 +/- 2.59 and 43.02+/-0.98, respectively. Likewise, the TP of' not-glazed'and' glazed'group of STV specimens at 0.3 mm thickness were 47.03 +/- 3.65 and 50.95 +/- 3.05 and the TP at 0.6 mm thickness group were 34.48 +/- 1.28 and 43.39 +/- 1.20, respectively. As the glazing of ceramic veneer differed, the TP of each ceramic veneer showed statistically significant difference. But, the result between the products was not statistically different.
CONCLUSION
Within the limitations of this study, we are concluded that the glazing process changed translucency of laminate ceramic veneers and the TP would not be affected by products.
