Micro-computed tomography of teeth as an alternative way to detect and analyse vitamin D deficiency

International audienceThis contribution presents the first application of micro-computed tomography (μCT) to study pathologicalmineral defects associated with vitamin D deficiency, namely interglobular dentine (IGD), within the mineralmatrix of archaeological teeth from three French medieval cases. To date, such an approach has only been usedonce in a clinical setting. Through this work, we evaluate potential benefits of this alternative approach and thecontribution such work could make to anthropological debates, through analysis of rare teeth of human or nonhumanfossils or teeth of individuals where more destructive techniques cannot be applied
