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.
