Key Findings
- 01Staining solutions significantly impacted both color change (ΔE) and translucency parameter change (ΔTP) across all tested ceramic materials.
- 02Coffee caused a more pronounced color change than distilled water.
- 03The zirconia-reinforced lithium silicate (ZLS) group exhibited the least color change and maintained the highest translucency.
- 04Lithium disilicate (LD) group showed the least change in translucency.
Application
Design takeaway
Designers must select CAD-CAM ceramic materials that offer superior color stability and translucency retention when exposed to common environmental staining agents, or develop protective surface treatments.
How to apply
When specifying materials for products where color and translucency are critical (e.g., architectural elements, consumer electronics, medical devices), conduct or consult research on the material's resistance to common environmental contaminants and wear.
Project actions
- 01When choosing materials for a design project, consider how they might react to everyday substances.
- 02Document any observed changes in material properties (like color or texture) after exposure to different conditions.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Controlled experimental environment.
- +Statistical analysis of results.
Limitations
The number of materials and staining solutions tested was limited. Real-world exposure conditions might be more complex.
Reliability & validity
The use of standardized measurements (colorimeter, spectrophotometer) and statistical analysis (ANOVA, Tukey's test) enhances the reliability and validity of the findings regarding color and translucency changes.
Think critically
How might the findings on color and translucency change in dental ceramics be applied to other product design fields where aesthetic longevity is important, and what new research questions arise?
Design Principles
"Material-environment interaction dictates long-term aesthetic performance."
Understanding how different staining agents interact with various ceramic materials is crucial for designers and manufacturers aiming to achieve predictable and stable aesthetic results in dental restorations and other visually sensitive applications. This knowledge informs material selection and finishing processes to meet user expectations for appearance over time.
What This Means for Your Design
Different types of ceramic materials used in computer-aided design and manufacturing (CAD-CAM) change color and transparency differently when exposed to staining liquids like coffee. Some ceramics are better at keeping their original look.

Paragraph starter
The selection of CAD-CAM ceramic materials for aesthetic applications must consider their susceptibility to staining. Research indicates that materials like zirconia-reinforced lithium silicate (ZLS) demonstrate superior color stability and translucency retention compared to other ceramics when exposed to common staining agents such as coffee, suggesting that material choice directly impacts the long-term visual integrity of the final product.
