Description:
Age-at-death estimation is one of the most important aspects of bioarchaeological and forensic investigations. A set of analysis carried out with the osteological sample recovered from Chenque I site (Lihue Calel National Park, La Pampa province, Argentina) aims to test the applicability of multiple methods to obtain reliable information about its demographic composition and structure. In the present paper the results of the evaluation of the structure of uniradicular teeth are presented and discussed. It has been previously stated that chronological age is highly correlated with pulp dimensions in these teeth, because dentine deposition continue during all life. Strong correlation has been also identified with periodontal retraction and apical translucency. The analysis of the structure of these teeth offers useful information in order to obtain age-at-death estimations of the individuals they belonged to. Dental age-at-death estimations of the control sample were obtained evaluating some skeletal markers (pubic symphysis and auricular surface of coxae), and then compared with the dental analysis. The formulae whose results showed strong correlations with the skeletal estimations were applied to another sample, composed of teeth that were not associated with any skeletal marker of age. The evaluation of premolars and lower central incisors offers estimations that are consistent with those obtained from the evaluation of the pelvic bones, so that the application of these formulae is an alternative method to obtain estimations in archaeological samples from similar contexts.
