Economic globalisation has been associated with a rise of cross-border migration in Europe. In France, courts commonly demand appropriate medical tests aimed at age estimations of supposed minors without documentation. Determining the age of foreign adolescents may be important in order to define the rights and protection afforded them by law depending on this status, and the conditions in which they may be detained or held in police custody if they are under suspicion. Age estimation is considered to be ideally based on the combination of clinical, skeletal, and dental examinations. A number of forensic physicians do not integrate published recommendations or the results of published studies into their daily practice. Previous studies have shown that medical practice is heterogeneous in this area. Factors determining this heterogeneity are unknown.

We hypothesize that the personal and professional development of the physician, as well as the characteristics and the circumstances of medical examination can affect medical response on age determination, beyond clinical and radiological data. The purpose of this study is to identify factors determining medical response to courts.
