    This study on dental arch dimensions found significant sex-based differences in anterior tooth width, but not for the upper central incisor. Specific ratios were identified between upper and lower anterior teeth widths.

    Area of Science:

    • Dental Anatomy
    • Anthropometry
    • Forensic Odontology

    Context:

    • Understanding the relationship between upper and lower anterior teeth dimensions is crucial in various dental applications.
    • Previous research has explored dental arch dimensions, but specific ratios between anterior teeth across sexes require further elucidation.

    Purpose:

    • To investigate the relationship between the widths of upper and lower anterior teeth in young adults.
    • To determine if significant sex-based differences exist in these dental measurements.
    • To establish specific proportional relationships between different anterior tooth segments.

    Summary:

    • Measurements of upper central incisor, six upper anterior teeth, and six lower anterior teeth were taken from 98 dental casts (50 female, 48 male, ages 22-27).

  • Results indicated statistically significant sex differences in the width of upper and lower anterior teeth, but not for the upper central incisor alone.
  • Established ratios include 1.3 between upper and lower teeth, 6.1 for upper anterior teeth to upper central incisor, and 4.7 for lower anterior teeth to upper central incisor.
  • Impact:

    • Provides valuable data for anthropological and forensic odontology applications.
    • Contributes to a better understanding of dental dimorphism and its implications in clinical dentistry.
    • Offers reference ratios for dental professionals in treatment planning and esthetic evaluations.
