“…Just as in the studies conducted by Lamendin , Prince & Ubelaker , and Megyesi , various teeth belonging to the same subject were included. This is a source of bias according to some authors , because it reduces variability within the sample (e.g., some samples may not show independence). Our study has revealed a certain level of variability in each case, even when it involved teeth from the same individual.…”

Age estimation of nonliving subjects plays a very important role in identifying human remains. When adult remains are in question, this process becomes even more complex. Among the numerous dental methods that exist for adults aging, the evaluation of root translucency is one of the most useful. This study studies the correlation between age and root translucency by investigating monoradicular teeth affected by pathological processes using the equations proposed by Lamendin, Prince & Ubelaker and from Singhal et al. The average age values calculated according to the three methods were compared with the values of known age. Age estimation using the Student's t-test resulted as more accurate in the methods by Singhal et al. and by Prince & Ubelaker, with respect to that of Lamendin. Age estimation based solely on the percentage of radicular dentinal translucency has been found to be more accurate when diseased teeth are involved.

“…Research on estimation methods for the age of adult skeletons is still a developing area in both fields. It is now well established that inter-individual variability of age-related bone changes are caused by a complex interaction between many factors, and that the observed pattern may be different depending on the population under study [1][2][3][4][5][6][7][8].…”

We discuss here the estimation of age at death from two indicators (pubic symphysis and the sacro-pelvic surface of the ilium) based on four different osteological series from Portugal, GreatBritain, South Africa or USA (European origin). These samples and the scoring system of the two indicators were used by Schmitt et al. (2002), applying the methodology proposed by Lucy et al. (1996). In the present work, the same data was processed using a modification of the empirical method proposed by Lucy et al. (2002). The various probability distributions are estimated from training data by using kernel density procedures and Jackknife methodology. Bayes's theorem is then used to produce the posterior distribution from which point and interval estimates may be made. This statistical approach reduces the bias of the estimates to less than 70% of what was obtained by the initial method. This reduction going up to 52% if knowledge of sex of the individual is available, and produces an age for all the individuals that improves age at death assessment.

“…These collections have mainly been used as a foundation for the development of standardized methods in order to estimate biological characteristics on unknown individuals from their skeletal remains, which is of the utmost importance in both archaeological and forensic contexts (Anderson et al, 2010;Auerbach and Ruff, 2004;Brooks and Suchey, 1990;Loth and Henneberg, 1996;Lovejoy et al, 1985;Schmitt et al, 2010;Steyn andİş can, 1997;Todd, 1920;Trotter and Glaser, 1952;Walker, 2005).…”
