Age-at-Death Estimation using Dental Root Translucency: The comparison of seven published formulae and the development of a new formula using dental root translucency as an age-at-death parameter, based on a 19th-century Dutch sample

Dental root translucency (alsoroot transparency, apical translucencyor transparency or root dentine sclerosis) has long been used to estimate age-at-death in forensic as well as archaeological human remainsbut has never been tested on a Dutch archaeological collection with known sex and age-at-death individuals. This thesis testedseven already existing (sets of) formulae using dental root translucency as a parameter, that weredeveloped on samples from various geographical regions, on the known sex and age-at-death sample from the Middenbeemster Collection housed at the Laboratory of Human Osteoarchaeology at the Faculty of Archaeology in Leiden University, The Netherlands. A total of 77 individuals werestudied, resulting in age-at-death estimations for 67 of theseindividuals.

To test if a more accurate formula could be developed for the Middenbeemster Collection, and even Dutch osteoarchaeological human remains, several new formulaewere trailedresulting in the following formula (T = translucency in mm):Age =19.832+7.667*T +-0.299*T2.With this formula, no statistical difference was found between males and females and seemed not to be affected by dental disease.The new formula was tested on twenty-onenew individuals from the Middenbeemster Collection and twenty individuals from Arnhem, Eusebiuskerk, allonly having an estimated osteological age category. The newly derived formula performed well in the forty-one newly studied individuals, bringing the total number of studied individuals with an age-at-death estimation to 108 individuals. The small sample size and slight underrepresentation should be addressed in future research that either has to enlarge the known age-at-death sampleand/or enlarge the estimated age-at-death sampleto test the presented formula of this thesis.Show less
