Implication

Morphometric CT analysis reveals distinct age-related maxillary bone shape variations in Malaysian adults, highlighting potential utility for forensic age estimation.

Key Points

To evaluate age-related morphological variations of the maxillary bone using 3D geometric morphometrics applied to head and neck CT scans.
Analyzed 413 adult head and neck CT scans with equal sex distribution across three ethnic groups (Malay, Chinese, and Indian) categorized into four age brackets (18–30, 31–40, 41–50, and 51–65 years).
Placed 45 3D anatomical landmarks on the maxilla and evaluated morphological variation using Procrustes ANOVA, canonical variate analysis (CVA), and discriminant function analysis (DFA).
Procrustes ANOVA demonstrated statistically significant differences in maxillary bone shape across age cohorts (p < 0.001).
Discriminant function analysis achieved age group classification accuracies ranging from 70.8% to 78.4%.
