Do Bolton's ratios apply to a Spanish population?

Summary

Spanish subjects exhibit distinct Bolton ratios, with significant discrepancies noted in 21% for anterior and 5% for total tooth-width ratios compared to established standards. This suggests a need for population-specific guidelines in dental analysis.

Area of Science:

  • Dentistry
  • Orthodontics
  • Anthropology

Background:

  • Interarch tooth-size relationships vary across populations.
  • Previous research indicates unsystematic differences in tooth dimensions.
  • Bolton ratios are crucial for assessing tooth-size discrepancies.

Purpose of the Study:

  • To determine the Bolton ratios specifically for Spanish subjects.
  • To compare Spanish Bolton ratios with existing international standards.
  • To identify potential population-specific needs for orthodontic treatment planning.

Main Methods:

  • A digital measurement method was employed on 100 pairs of dental casts from Spanish individuals.
  • Measurements were taken to the nearest 0.05 mm.
  • Statistical analysis included the Kolmogorov-Smirnov test, t-test, and 95% confidence intervals.

Main Results:

  • The mean anterior tooth-width ratio was 78.32% ± 2.45% and the total tooth-width ratio was 91.97% ± 1.95% when sexes were combined.
  • No statistically significant differences in tooth-width ratios were found between male and female Spanish subjects.
  • Significant differences were observed between the Spanish sample's Bolton ratios and previously established Bolton standards.

Conclusions:

  • A notable percentage of Spanish subjects (21% anterior, 5% total) presented discrepancies exceeding two standard deviations from Bolton's norms.
  • The findings suggest that existing Bolton ratios may not be universally applicable.
  • Development of specific Bolton ratio standards for the Spanish population may be warranted to improve diagnostic accuracy in orthodontics.
