摘要

X-ray absorption microtomography, a high resolution variant of medical “CT”, and synchrotronrnx-ray phase contrast imaging reveal the distribution of mineral within teeth of the sea urchinrnLytechinus variegatus. Data from these imaging modalities on intact teeth are compared withrnhistochemically stained thin sections observed with transmission optical microscopy. Becausernthese teeth grow continuously, the complex variation of attenuation from aboral to incisal endrnshows how the sea urchin increases mineralization to produce a hard, self-sharpening cuttingrnedge. The phase contrast radiographs appear to show the calcite crystal morphology withrngreater sensitivity, at least in some portions of the tooth.
