A análise de três dentes decíduos de restos fetais do enterramento de Ostuni I (Itália, circa 27.000 anos BP) através de histologia virtual permitiu refinar a estimativa da sua idade gestacional, que varia entre as 31 e as 33 semanas. Face aos resultados obtidos anteriormente a partir do comprimento da diáfise dos ossos longos – entre as 34 e as 36 semanas – os autores do estudo consideraram que a estimativa da idade gestacional em fetos pré-históricos não deverá fundamentar-se em referências modernas. Neste trabalho, estimou-se a idade gestacional do feto de Ostuni a partir de modelos de regressão produzidos numa amostra moderna de referência, obtendo-se um intervalo compreendido entre as 31,2 e as 33,6 semanas, bastante similar ao intervalo reportado por Nava et al.
ABSTRACT - The analysis of three deciduous teeth from the Ostuni I fetus (Italy, circa 27,000 years BP) through virtual histology sanctioned the refinement of fetal gestational age, currently established between 31 and 33 weeks. Challenging previous results obtained from the diaphyses of long bones – between 34 and 36 weeks – the authors of the study considered that the estimation of gestational age in pre-historical fetuses should not be grounded in modern reference standards. In this work, gestational age of the Ostuni fetus was estimated from regression models developed in a modern reference sample; a gestational age of 31.2 – 33.6 weeks was obtained, a very similar interval to that reported by Nava et al.
