Human dentinal structure as an indicator of age.
Odontological data can constitute essential evidence for age estimation in forensic work. In this research the structural differentiation of dentine was correlated with chronological aging after SEM and EDXA examinations were performed on extracted human teeth ranging in ages between 25 and 74 years. EDXA showed that the spherical structures within the dentine observed were comprised of calcium phosphate. They were then counted and their state of fusion noted and the statistical "Z" test applied to the different age groups. The results demonstrated a correlation between the fusion of calcospherites and age in all layers of the dentine.
