In subadult age estimation, which method is most closely correlated with chronological age?

• A. Dental development
• B. Diaphyseal length
• C. Pubic symphysis
• D. Auricular surface

Answer: (A)

Dental development tracks chronological age most closely in subadult remains because the timing of tooth formation, mineralization, and eruption follows a relatively consistent schedule. These dental stages have been documented in developmental charts, so comparing an observed dentition to these stages yields age estimates with relatively small and predictable margins. In contrast, diaphyseal length reflects overall growth and body size, which vary a lot with genetics, nutrition, and health, making it less precise for pinpointing age in subadults. The pubic symphysis and auricular surface changes are features that become informative mainly in adults, or at least are not reliably staged for precise subadult ages. So, dental development provides the strongest and most reliable correlation with chronological age among these methods.
