Dental Age Assessment
A forensic and paediatric dental research method using tooth development stages or eruption patterns to estimate a subject's chronological age.
Full Definition
Dental age assessment involves evaluating dental maturity—through radiographic analysis of tooth mineralisation stages, root development, or eruption status—as a proxy for chronological age. Widely used methods include the Demirjian method, the Willems modification, and the London Atlas. In forensic odontology and paediatric dental research, editors should verify that the specific method and reference population used are clearly cited, as accuracy varies across ethnic groups and skeletal maturity indicators. The term 'dental age' is distinct from 'skeletal age' (determined by bone development) and 'chronological age' (actual age in years), and manuscripts must not conflate these constructs. Statistical agreement between estimated dental age and chronological age is typically reported using intraclass correlation coefficients or mean absolute error.
Usage
Usage note: Always specify the method and reference population used; the Demirjian and Willems methods produce systematically different estimates and are not interchangeable.
In Context
- "Dental age assessment was performed using the Demirjian seven-tooth method on digital orthopantomograms of 300 children aged 6–14 years." — Forensic odontology research methods
- "The manuscript incorrectly equated 'dental age' with 'chronological age' in the discussion; the editor inserted a clarifying sentence distinguishing the two constructs." — Manuscript correction note
