Population-Specific Histological Age-Estimating Method

Previously developed histological age-estimating methods have been based on samples lacking interpopulation variability. A comparison of age-associated rib histomorphometrics between an European-American sample and an African-American sample indicates that ethnicity can have a significant effect on osteon population density (OPD), osteon cross-sectional area (On.Ar), and relative cortical area (Ct.Ar/Tt.Ar) Based upon these findings, new histological age-predicting formulae are presented that are recommended when estimating age for African-American or European-American skeletal remains. A general formula that is applicable to remains of unknown ethnicity is also provided.
