Age estimation of living individuals

Age estimation of living individuals is carried out by estimating the biological age when the chronological age of the individual is unknown or uncertain because of the lack of valid identity documents. It is used to confirm if an individual has reached a specific age threshold in cases of criminal liability, asylum seekers and unaccompanied children, human trafficking, adoption, and competitive sports. Guidelines by the Study Group on Forensic Age Diagnostics (Arbeitsgemeinschaft für Forensische Altersdiagnostik, AGFAD), propose that a three-step procedure should be followed for the age estimation: the first step is a physical examination; the second step include the assessment of the hand/wrist development using plain radiographs; the third step is a dental assessment. One of the most used methodologies for the estimation of age from the development of the hand and wrist is the Greulich and Pyle Atlas, whilst to assess dental development the most common method used so far is the 8-teeth technique developed by Demirjian et al.. Where the estimated age of the individual might be above 18 years of age, it is possible to use the development of the medial end of the clavicle. Traditionally, those undertaking age estimation in the living, adopt imaging techniques such as plain radiographies and CT scans to carry out the age estimation, however, lately, due to ethical issues surrounding the use of ionising medical imaging modalities for non-medical purposes (e.g., forensic purposes), magnetic resonance imaging, a radiation free medical imaging modality, is being investigated to develop new methodologies to estimate the age of living individuals.
