Aportaciones de la paleohistología humana al estudio de biomateriales

Abstract

The deep study of archaeological human bone could provide relevant information to biomaterials science, as it could tell how the implant process of bioglasses and bioresorbable ceramics is. In this paper, we propose to study, by means of different microscopic, spectroscopic, and X-ray diffraction techniques, the histological and mineral bone variability throughout ontogeny. Extrapolating this data, we could have a better knowledge of biodegradable materials implant. In different ages, we could notice different tissues in cortical bone: fibrolamellar bone is characteristic of early stages of life while secondary or harvesian bone is in adult individuals. Raman and infrared spectroscopy suggest an increase of critallinity in the inorganic matrix during live. Finally, the X-ray diffraction study of bone tissue shows β-calcium phosphate and hydroxyapatite as the main mineral bone components.
