The golden proportion, a classic aesthetic principle, is not consistently found in the natural proportions of maxillary anterior teeth across diverse global populations. This classic design research insight is drawn from a 2022 study published in Applied Sciences. Using Systematic review, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing for aesthetic outcomes, especially in human-centric applications, move beyond rigid, classical proportions and embrace the diversity of natural forms and culturally influenced aesthetics.

Golden Proportion in Natural Teeth: A Myth Across Global Populations

The golden proportion, a classic aesthetic principle, is not consistently found in the natural proportions of maxillary anterior teeth across diverse global populations.

Applied Sciences · 2022

01

Key Findings

  • 01The mean predicted dental ratios were often larger or smaller than the successive widths of maxillary natural anterior teeth.
  • 02Golden proportions were not consistently found among anterior teeth in different observed populations.
  • 03Anterior tooth proportions differ among populations based on geographic, ethnic, and racial background.
02

Application

Design takeaway

When designing for aesthetic outcomes, especially in human-centric applications, move beyond rigid, classical proportions and embrace the diversity of natural forms and culturally influenced aesthetics.

How to apply

In product design, consider how different user groups might perceive and interact with aesthetically designed elements. For example, in interface design, test color palettes and layout proportions with diverse user groups to ensure broad appeal and usability.

Project actions

  • 01When researching classic design principles, always investigate their applicability across different cultures and user groups.
  • 02Consider how historical aesthetic ideals might not align with contemporary or diverse user needs.

Method & Evidence

AimDoes the golden proportion (1:1.618) exist in the natural widths of maxillary anterior teeth across different global populations?
MethodSystematic Review
ProcedureA systematic review was conducted by searching multiple electronic databases (PubMed, Medline, EMBASE, Scopus, Science Direct, Web of Science, Cochrane Library) for studies published between January 2000 and September 2020 that investigated the golden proportion in natural maxillary anterior teeth across different populations. Fifty-two full-text articles were included in the final analysis.

Variables

IVGeographic, ethnic, and racial background of populations
DVPresence and adherence to the golden proportion in natural maxillary anterior teeth widths
CVNatural maxillary anterior teeth, aesthetically pleasing smiles

Strengths & Limitations

Strengths

  • +Comprehensive search strategy across multiple databases.
  • +Inclusion of a significant number of studies for analysis.

Limitations

The study's findings are specific to dental aesthetics and may not directly translate to other design fields without further investigation.

Reliability & validity

The reliability of the systematic review is enhanced by the rigorous search methodology and the inclusion of multiple studies. Validity is supported by the focus on natural teeth and the systematic approach to data extraction, though the subjective nature of 'aesthetically pleasing' in the original studies could be a limitation.

Think critically

If the golden proportion is not a natural standard, what other factors contribute to perceived aesthetic appeal in different cultures, and how can designers research and incorporate these factors?

05

Design Principles

"Aesthetic principles should be validated against diverse populations and individual variations, rather than assumed to be universally applicable."

This finding challenges the universal application of the golden proportion as a sole determinant of aesthetic dental design. Designers and researchers should be aware that aesthetic ideals can be culturally and ethnically influenced, necessitating a more nuanced approach to design that considers individual and population-specific variations.

06

What This Means for Your Design

Even though the 'golden ratio' is often thought of as the perfect proportion for beauty, this study found that natural teeth in people from different parts of the world don't actually follow this rule. What looks good can be different depending on where someone is from.

How to use in your project

  • 1.Reference this study to justify why a design might deviate from a classic proportion, arguing for a more context-specific or user-centered approach.

Paragraph starter

This systematic review highlights that classic aesthetic principles, such as the golden proportion, are not universally present in natural human forms across diverse global populations. The research indicates significant variations in tooth proportions based on geographic, ethnic, and racial backgrounds, suggesting that a singular aesthetic standard may be inappropriate for design applications aiming for broad appeal or cultural sensitivity.
