AbstractSince 2000, Roberto Cameriere and his team at the Institute of Legal Medicine, University of Macerata (Italy) have been studying new methods for age estimation in both living and dead subadults and adults, obtaining linear regression formulas for age estimation from both teeth and hand-wrist.As regards age estimation in children using teeth, age was modelled as a function of gender (g),morphological variables (predictors) × 5(second premolar), s (sum of normalised open apices) N0 (number of teeth with apex closed), and the first-order interaction between s and N0. As regards age estimation in non–adults using carpals and epiphyses of radius and ulna, the ratio between the total area of carpal bones and the epiphyses of ulna and radius (Bo) and Ca was calculated. This ratio (Bo/Ca) was used for linear regression analysis. Lastly, age estimation in adults according to dental maturity was evaluated by measuring the pulp/tooth area ratio on upper (×1) and lower (×2) canines.All formulas can be found in the web site http://agestimation.unimc.it via an Excel page. Also published is a handbook with many simple explanations and easy texts. The handbook gives information on how both to digitalise the images and how to use the tools of Adobe Photo Shop.
