This in vitro study aimed to evaluate the final shade of translucent zirconia laminate veneers with varying thicknesses over teeth with different shades. Seventy-five chairside computer-aided design/computer-aided manufacturing (CAD/CAM) shade A1 third-generation zirconia dental veneers, with thicknesses of 0.50 mm, 0.75 mm, and 1.00 mm, were placed on resin composite teeth with shades ranging from A1 to A4. The laminate veneers were divided into groups based on thickness and background shade. All restorations were evaluated with a color imaging spectrophotometer, to map the veneer surface from A1 to D4. Regardless of the thickness or background shade, all dental veneers showed color alteration from the original shade. Veneers with 0.5 mm thickness tended to display the B1 shade, while veneers with 0.75 mm and 1.0 mm thickness primarily exhibited the B2 shade. The thickness of the laminate veneer and background shade significantly modified the original shade of the zirconia veneer. One-way analysis of variance was performed and a Kruskal–Wallis test was used to determine the significance between the three veneer thicknesses groups. The results indicated that the thinner restorations showed higher values with the color imaging spectrophotometer, suggesting that thinner veneers may result in more consistent color matching. This study underscores the importance of carefully considering thickness and background shade when selecting zirconia laminate veneers, to ensure optimal color matching and overall aesthetic outcomes.
Background: Clinical feedback occurs in hierarchical, time-pressured settings. Objective: This Perspective proposes relational wellness as a dyadic condition of a feedback episode and describes a brief feedback heuristic. Approach: The framework was developed before the focused, non-systematic searches used to check and align specific claims with sources. We compare SEED with established approaches and map its rationale, boundaries, and testable mechanisms. Key Propositions: In a relationally well feedback episode, learner and educator can remain respected and connected while engaging in truthful learning work. The author-developed SEED heuristic comprises See the situation and invite perspective; Explain observed performance and significance; Extend one prioritized next step collaboratively; and Dialogue to check understanding and invite response. Dignity governs all moves. Safety instructions may precede dialogue. SEED overlaps with Ask–Tell–Ask and remains unvalidated. Conclusions: Separate construct development should test the proposed level, dimensions, and discriminant validity of relational wellness using both participants’ perspectives. Co-design, technical and cultural review, feasibility work, and comparative evaluation are required before effectiveness claims.
