Objectives: The purpose of this study was
to investigate the effect of material and thickness on the translucency
parameters (TP) and opalescence parameters (OP) for resin matrix ceramic
blocks. Materials and Methods: 90 disc-shaped specimens (8 mm diameter and A2
shade, High Translucency) were fabricated from Vita Enamic, Lava Ultimate and
GC Cerasmart resin-matrix ceramic blocks and prepared to thicknesses of 0.5 mm,
1 mm and 1.5 mm (n=10). A dental
spectrophotometer (VITA Easyshade Advance) was used to calculate
the TP and OP. All specimens were placed on white and black backgrounds.
The color measurements were repeated
three times for each of the specimens and the mean values of L, a and b were
calculated. Data were analyzed by a two-way
analysis of variance (ANOVA) and Tukey’s test. Results: For the 0.5 mm thickness groups, GC Cerasmart had the
highest and Vita Enamic had the lowest TP values. For the 1 mm
thickness groups, GC Cerasmart had the highest TP, whereas Vita Enamic had
the lowest TP. For the 1.5 mm thickness groups, Lava Ultimate had the
highest TP, whereas Vita Enamic had the lowest TP. For the 0.5 mm
thickness groups, Vita Enamic, and GC
Cerasmart had the highest and lowest OP, respectively. The OP values in
the 1 mm thickness group of Vita Enamic groups were higher than the GC
Cerasmart and Lava Ultimate groups. The OP values in the 1.5 mm thickness group
Lava Ultimate group were higher than the GC Cerasmart and Vita Enamic groups.
In all groups, the OP values showed an increase
in parallel with the increase in thicknesses, in contrast, the TP values showed a decrease.
Conclusions: Type and thickness of
the resin matrix ceramics affect the
optical properties of the materials.
