Micro-CT images of the rat mandibular alveolar bone and the mandibular first molar.

<p>a,b,c,d were obtained from a sham rat, while e,f,g,h were obtained from an ovariectomied rat. a,b,e,f showed the coronal surface passing the centers of the buccal root and the lingual root. c,d,g,h showed the horizontal surface which was parallel to the occlusion plane. M1, the mandibular first molar; M, mesial root; B, buccal root; D, distal root; L, lingual root. T1 and T2, two horizontal surfaces passed the alveolar ridge crest and apex of the buccal root separately and were parallel to the occlusion plane. a,c,e,g showed two-dimensional images, b,d,f,h showed three-dimensional images. In the 3D reconstruction images, the deep brown part represented alveolar bone and the white part represented the region of interest (ROI).
