Abstract

Background: The selection of the appropriate cement for porcelain veneers, especially on single teeth, is crucial because the color match of the cement with their respective try-in paste will impact the final color of the restoration. Objectives: To evaluate and compare the color correspondences between Variolink Esthetic LC resin (Ivoclar, Schaan, Liechtenstein) and Vitique (DMG - Hamburg, Schleswig-Holstein, Germany) with their respective try-in paste as well as the final porcelain veneer restoration. Materials and methods: A controlled clinical trial was conducted on patients indicated for porcelain laminate veneers at Van Lang University and EMCAS Cosmetic Hospital in Ho Chi Minh City from September 2023 to April 2024. The CIELAB color system (parameters a*, b*, and L*) was used to analyze color at various assessment points including color trial (T1), before cement polymerization (T2), after complete cement polymerization (T3), and three months post-restoration (T4). Results: A total of 20 participants with 30 teeth underwent restoration, evenly divided between the two groups. The mean age of the study population was 36.2 ± 8.1, with females comprising three-quarters of the patients. All restored teeth were anterior teeth, with the central incisors being the majority (56.7%). Color analysis showed that the L* parameter in the Vitique group was significantly higher (lighter) compared to the Variolink group at all assessment points (p < 0.05). Conversely, no significant differences were observed in the a* and b* parameters between the two groups (p > 0.05). The study recorded noticeable color changes (∆E) between the time points T1-T3, T2-T3, and T3-T4. Vitique cement (∆E corresponding to 3.0 ± 0.9, 3.5 ± 1.2, and 2.8 ± 1.0) tended to have better color compatibility than Variolink cement (∆E corresponding to 3.4 ± 1.3, 3.8 ± 1.5, and 3.1 ± 1.0), however, the differences were not statistically significant (p > 0.05). Conclusion: Vitique cement showed better lightness compared to Variolink cement, however, there was no significant difference in the color correspondences of the two types of cement with their respective try-in paste and the final color of the porcelain veneers.
