Fetal Age Assessment From Primary Teeth and Long Bones.

This study evaluated traditional and expedited methods for assessing the age of fetal remains. Because of their rare occurrence, the discovery of fresh, decomposing, disfigured, or skeletal fetuses engenders heightened awareness by forensic pathologists primarily tasked with age estimation in relation to viability. With decomposed complete or isolated fetal remains, dentists focus on primary molar mineralization, whereas anthropologists perform long bone measurements along with discernment of other indicators of skeletal maturity to obtain an age estimation.The results of this study are 4-fold: (1) The "best" technique for harvesting fetal tooth buds and long bones is the dissection of the developing tooth buds with maceration for the long bones. (2) Metric analysis was applied to the tooth buds and long bones for age estimation, and the findings were correlated. (3) There is a statistically significant difference between known age and dental age and between dental age and long bone age. The difference between known age and long bone age is not statistically significant, but a type II error exists because of the small sample size. (4) A central incisor staging technique for fetuses younger than 26 weeks was developed as a supplement to the molar staging system of Kraus and Jordan (1965).
