The core technique in the determination of age at death of skeletons.

This study proposed an histological method of estimating age at death in skeletons that uses a 0.4-cm-diameter core of cortical bone. Age-estimating regression equations were generated from data obtained from the analysis of bone cores taken from femurs, tibiae, humeri, and ulnas of cadavers. When the regression equations generated in this study were applied to eight forensic science cases, accurate ages at death were estimated.
