Three-dimensional microtomography reconstructions of left deciduous teeth in sheep showing the four incisors (i
) and the second premolar (p
). The investigated teeth are presented in dorsal/posterior (D/P), ventral/anterior (V/A), mesial/bucall (M/B) and distal/lingual (D/L) views, respectively. The volumetric tooth mineral density (vTMD) was determined in volumes-of-interest (VOIs) separately for whole enamel (volumetric enamel mineral density – vEMD) and for whole dentine (volumetric dentine mineral density – vDMD). Using the same VOIs, total enamel volume (Evol) and total dentine volume (Dvol) were measured automatically for each tooth.
