- Evidence
- Moderate effect
The presence of dental plaque, tooth fractures, composite fillings, and crowns negatively impacts patient satisfaction with the appearance of their anterior teeth. This user-centred design research insight is drawn from a 2016 study published in Vojnosanitetski pregled. Using Cross-sectional study combining clinical examination with a self-administered questionnaire. with 700 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize the long-term aesthetic integrity and perceived naturalness of dental restorations, as visible flaws significantly reduce user satisfaction.

Key Findings
- 01Presence of dental plaque was a significant negative predictor of satisfaction.
- 02Tooth fractures were negatively associated with satisfaction.
- 03Composite fillings were a significant negative predictor of satisfaction.
- 04Crowns were also negatively associated with satisfaction.
- 05Tooth shape, age, and gender were not significant predictors of satisfaction.
Application
Design takeaway
Prioritize the long-term aesthetic integrity and perceived naturalness of dental restorations, as visible flaws significantly reduce user satisfaction.
How to apply
When designing or selecting materials for dental restorations, consider their propensity to stain, fracture, or degrade over time, as these factors directly impact patient perception and satisfaction.
Project actions
- 01When researching user satisfaction, consider both the functional and aesthetic aspects of a product.
- 02Investigate how the material properties of a product can influence its perceived quality and user perception over time.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Large sample size.
- +Inclusion of both clinical examination and self-reported data.
Limitations
The study's findings might be specific to dental aesthetics and may not directly translate to all product design contexts. The relatively low percentage of explained variance suggests other factors are at play.
Reliability & validity
The study's validity is supported by the use of a regression model to identify independent predictors. Reliability could be enhanced by standardizing clinical examination protocols and ensuring consistent questionnaire administration.
Think critically
Given that tooth shape, age, and gender were not significant predictors, what other psychological or social factors might be more influential in determining satisfaction with dental appearance?
Design Principles
"Aesthetic satisfaction is contingent on the perceived condition and integrity of visible elements, not just their form."
This research highlights that aesthetic outcomes are not solely determined by the ideal form or function, but critically by the perceived condition and integrity of dental work. Designers and manufacturers of dental materials and prosthetics should consider how their products contribute to or detract from a patient's overall satisfaction with their smile.
What This Means for Your Design
If a dental filling or crown looks obviously artificial or gets dirty easily, people won't be as happy with their smile.
How to use in your project
- 1.Use this study to justify the importance of user satisfaction with aesthetics in your design project.
- 2.Refer to the findings to explain why certain material choices or design features might negatively impact user perception.

Paragraph starter
Research indicates that user satisfaction with visible product elements is significantly influenced by their perceived condition and integrity over time. For instance, in dental aesthetics, the presence of plaque, fractures, or visible restorative work like composite fillings and crowns has been shown to negatively impact patient satisfaction, even when the underlying function is sound. This highlights the importance of designing for long-term aesthetic durability and minimizing visible imperfections.
