Medico-legal age estimation is one of the tasks in clinical forensic medicine. In many instances, the courts of law seek medical opinion on the age of an individual. The circumstances may be civil, like to find the date of retirement in cases where the birth record is not available or criminal as in cases of child labour, juvenile delinquency, rape, kidnapping from lawful guardian, etc. There is a wide confusion and controversy regarding the standard method to be used for estimating age in the Indian Subcontinent. The aim of the current study is to find the correlation among the various parameters of commonly examined ossification centres, through which a regression formula with positive correlation and maximum coefficient of determination can be derived which can be attempted to be standardised for the estimation of age.
