Exploring the Relationship Between Mandibular Morphology, Dental Eruption, and Chronological Age in Modern Human Juveniles Through Geometric Morphometrics.

ABSTRACT:

Objective

This study investigated how mandibular morphological shape and dental eruption patterns reflect chronological age in modern human juveniles, using geometric morphometrics. The aim was to assess their variation, covariation, and the accuracy of classifying individuals into age-based groups using combined shape information.

Materials and methods

Computed tomography scans from a sex-balanced sample of 48 individuals, aged 4 to 13 years, sourced from the New Mexico Decedent Image Database, were used to generate 3D models of mandibular bodies and permanent dentition (incisors, canines, premolars, and first molars). Mandibular and dental morphology were analyzed using 3D landmark-based methods. Generalized Procrustes Analysis and Principal Component Analysis (PCA) assess
