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 ceramicveneer differed, the TP of each ceramic veneer showed statistically significant difference. But, the result between the products was not statistically different.
