Color Match of Porcelain Veneer Light-Cure Resin Cements with Their Respective Try-in Pastes: Chemical Stability
This study aimed to assess the color match of porcelain veneer light-cure resin cements with their respective try-in pastes. Ten disc-shaped specimens with 0.5 mm thickness and 7 mm diameter were fabricated from Choice 2, Panavia V5, and Variolink Esthetic resin cements using silicon molds, and then...

| description | This study aimed to assess the color match of porcelain veneer light-cure resin cements with their respective try-in pastes. Ten disc-shaped specimens with 0.5 mm thickness and 7 mm diameter were fabricated from Choice 2, Panavia V5, and Variolink Esthetic resin cements using silicon molds, and then light-cured. A cuvette was used for evaluating uncured resin cements and try-in paste specimens. The cured (n=30) and uncured (n=30) resin cement specimens as well as the try-in paste specimens (n=30) underwent reflectance spectrophotometry for determining their L*, a* and b* color parameters. The color difference (∆E) between the cement specimens and their try-in pastes in the three groups was calculated and analyzed using one-way ANOVA and Tukey’s test. Minimum ∆E was observed between the cured Variolink and its try-in paste (∆E=6.5), as well as between its cured and uncured specimens (∆E=6.2). The mean L* value of cured Variolink and its try-in paste was higher than the corresponding values for the other two cements. The cured specimens of Variolink showed higher mean a* and b* values than the cured specimens of the other two cements. The mean a* and b* parameters of Variolink try-in paste were also higher than the corresponding values in the other two try-in pastes. Try-in pastes can be used for the assessment of final color of cemented restorations. Cured Variolink and its try-in paste were lighter and yellower than the other two cements and their try-in pastes. |
