The TRI-DENTUM project aimed to investigate past human diets from an evolutionary perspective. It involved research in archaeology, biology, dentistry, and evolutionary medicine. The main aim was to build an innovative and multidisciplinary method to infer past human diets from the examination of dental remains. The diet of selected individuals recovered from two medieval cemeteries had to be studied and diet and dental status had to be reconstructed through an original, three-fold approach. Three independent analyses were applied: macroscopic analysis, radiology, and proteomics.
It is important to know how dental diseases evolved and the role of diet and behaviour in the process. This could potentially ameliorate dental conditions in the present populations.
Documenting oral diseases in ancient human remains is the first step toward a thorough reconstruction of the ancient epidemiology of these diseases.
The results of this project are the first step towards a more in-depth approach, including a larger number of archaeological sites. The main objective was to infer the dietary habits of medieval populations based on a combined method including the analysis of dental pathologies in selected individuals; analysis of dental calculus and analysis of the temporomandibular joint (TMJ) of the same individuals.
Since the two sites have different chronological dates, it was possible to apply an evolutionary approach when interpreting the results from dental paleo-pathologies and from ancient proteins retrieved from dental calculus.
