Abstract

Purpose: The aim of this study was to assess the color difference between try-in paste, uncured and cured resin cement using two cement shades on the final color of ceramic laminate veneer.Materials and methods: 15 ceramic veneers discs of shade A1 and 1mm thick were applied to 2mm composite resin discs using two shades of resin cement and their try-in paste produced by the same manufacturer.Assessment of color difference values (ΔE) between the translucent shade (control) and both the try-in paste and the cured resin and also between the uncured and cured resin was made. The obtained data were statistically analyzed using two-way ANOVA with Tukey’s post-hoc test.Results: There were no statistically significant difference between the try-in paste, uncured and cured resin cement of the same shade using the laboratory spectrophotometer (P ≤ 0.05). However, using the easyshade, there were statistically significant difference between the try-in paste and the cured resin cement of the same shade. Color differences produced between the try-in paste and the corresponding shade of cured resin cement ranged from ΔE 1.3 to 5. Low agreement between spectrophotometer and easyshade measurements was found (P = 0.624).Conclusions: Clinically no significant differences were found between the try-in paste and the corresponding cured resin cement of the same shade using the laboratory spectrophotometer. However, clinically significant differences were found using the easyshade. Therefore the color match achieved by the try-in paste has to be treated with caution and further assessment of the restoration made with the uncured resin cement in place before curing is recommended. The Easyshade clinical spectrophotometer is considered as a clinical adjunctive aid for tooth shade selection that cannot be used alone.
