I don't know if this helps but according to a recently published (2008) journal paper:

In line with recommendations issued by the Study Group on Forensic Age Diagnostics, for determining the age of live subjects a forensic age estimate should combine the results of a physical examination, an X-ray of the hand, and a dental examination which records dentition status and evaluates an orthopantomogram. To assess the age of persons who are assumed to be at least 18 years old, an additional roentgenographic or CT examination of the clavicles is recommended. If there is no legal justification for X-ray examinations, the range of possible methods is limited to a physical and a dental examination.
