Abstract:The reconciliation of skeletal and chronological age is of paramount concern in the context of criminal proceedings involving living individuals, who frequently lack any associated identification documentation, and are referred to the criminal justice system. It is important to appreciate that skeletal and chronological ages are not the same measurement of time-since-birth, and depending on the analytical approaches applied, there will be an inherent source of variation between estimated (biological: skeletal, physical, and psychological) and actual (legal) age. Given the evidentiary value attached to the estimation of age based on the subjective assessment of biological and psychological developmental attributes, it is timely to consider current approaches toward achieving the latter. The aim of this review is to first explore a selection of circumstances that result in requests for forensic age assessment in living individuals. Issues pertaining to competency to perform an assessment, sources of error that may be introduced, and how to accordingly quantify the level of uncertainty in the final estimation are then considered. This logically leads into discussions of the necessity for population-specific statistical biological data. Current methods based on psychological development, dental status, and skeletal maturation are then reviewed. The review concludes by exploring future research and practical directions in the context of medico-legal practice and social consequences.
