    Summary

    Pont's Index accurately predicts dental arch width in North Indian populations. This study found strong correlations between incisor width and both intermolar and interpremolar arch dimensions, validating its clinical use.

    Area of Science:

    • Dentistry
    • Orthodontics
    • Anthropology

    Background:

    • Pont's Index is a widely used tool for estimating dental arch dimensions.
    • Its applicability across diverse ethnic groups requires validation.
    • North Indian populations have distinct craniofacial characteristics.

    Purpose of the Study:

    • To assess the reliability of Pont's Index in a North Indian population.
    • To determine correlations between anterior and posterior dental arch widths in this demographic.

    Main Methods:

    • Evaluation of 100 dental models with normal occlusion.
    • Measurement of combined maxillary incisor widths.
    • Measurement of maxillary intermolar and interpremolar arch widths.

    Main Results:

    • Significant positive correlations were observed.
    • Strong associations found between combined maxillary incisor widths and maxillary intermolar arch widths.
    • Significant correlations also noted between combined maxillary incisor widths and maxillary interpremolar arch widths.

    Conclusions:

    • Pont's Index demonstrates reliability for predicting maxillary arch dimensions in the North Indian population.
    • The findings support the use of Pont's Index in orthodontic assessments for this ethnic group.
    • Dental arch width prediction is feasible using incisor measurements in North Indian individuals.
