The relationship between the gingival angle and the crown width-to-length ratio significantly influences the perceived squareness or roundness of anterior teeth. This human factors research insight is drawn from a 2022 study published in Cureus. Using Cross-sectional study with 110 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Incorporate measurements of gingival angle and crown width-to-length ratio when designing dental prosthetics or aesthetic simulations to achieve specific perceived tooth shapes.

Key Findings
- 01Mean values of crown width, crown length, crown width/length ratio, gingival angle, and interdental papilla height were lower in females than in males.
- 02A higher gingival angle and crown width/length ratio correlate with a square tooth appearance, while lower values correlate with a round or narrow appearance.
Application
Design takeaway
Incorporate measurements of gingival angle and crown width-to-length ratio when designing dental prosthetics or aesthetic simulations to achieve specific perceived tooth shapes.
How to apply
When designing a dental crown or veneer, consider the patient's sex and aim for specific gingival angles and crown width-to-length ratios to achieve a square or rounded aesthetic.
Project actions
- 01When designing a product that interacts with the human body, consider how anthropometric measurements can influence its perceived aesthetics and function.
- 02If your design involves facial features, research relevant anatomical proportions and how they are perceived.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Quantifiable measurements were used.
- +Statistical analysis was performed to identify correlations.
Limitations
The study's findings are specific to the population studied and may not apply universally. The subjective perception of 'square' or 'round' can vary between individuals.
Reliability & validity
The use of a calibrated vernier caliper enhances the reliability of measurements. The cross-sectional nature of the study provides a snapshot but may limit causal inferences, impacting external validity if applied to different populations without further research.
Think critically
How might these findings be applied to the design of non-dental products that aim to evoke a sense of 'sharpness' or 'softness' in their form?
Design Principles
"Aesthetic outcomes in dental design are influenced by quantifiable anthropometric ratios and angles."
Understanding these anthropometric and aesthetic relationships is crucial for designers involved in creating dental prosthetics, orthodontic appliances, or even digital avatars where facial aesthetics are simulated. It allows for more natural and aesthetically pleasing outcomes by aligning design choices with established human perceptual norms.
What This Means for Your Design
The way teeth look (square or round) depends on how the gums meet the teeth (gingival angle) and the tooth's own proportions (width vs. length). Males tend to have slightly larger teeth and gum angles than females.
How to use in your project
- 1.Use this research to justify design choices related to the proportions and angles of components that contribute to the overall aesthetic of your design, especially if it relates to human form or interaction.

Paragraph starter
The study by Bhavsar et al. (2022) highlights that the gingival angle and the crown width-to-length ratio are significant determinants of perceived tooth shape, with higher values correlating to a square appearance and lower values to a rounder one. This research is relevant to the design of dental prosthetics, as it provides quantifiable data to guide the creation of aesthetically appropriate tooth forms that align with specific user or population characteristics.
