Age determination in human adults by dental histology.
Dentine root transparency (RDT) has been measured on 70 histological sections of teeth from 46 individuals of known sex and age. In order to obtain the estimates of individual chronological age, Bang & Ramm (1970) equations have been applied to the value obtained by the measurements. Using the percentage ratio hx100/H (after Lemendin & Cambray 1981)--were h is the extension of the root transparency zone (in mm) and H is the total root length (in mm), some regression functions have been elaborated. The error of the age estimates obtained following Bang & Ramm was quite high in percentage, being comprised between +/- 5 years only in 21.13% of the cases.
