Figure 3. Micro-CT findings of the M2 alveolar bone. The tooth was virtually removed on the images. (A) 2D sagittal view at the center of M2. The Sham group showed larger bone volume with less bone marrow space. By contrast, the ovariectomized group showed less bone volume and increased marrow space. (B) 2D frontal view at the center of M2. The Sham group displayed normal trabecular network structure; the ovariectomized group featured disconnected trabeculae. (C) 3D images of the M2 interradicular septum showing an abundance of rod-like trabeculae in the ovariectomized group, whereas those in the Sham group are principally plate-like. (D) Buccal view of the alveolar socket. The buccal wall was virtually removed on the images. Significantly more pores are visible in the alveolar socket at the top of the interradicular septum (arrow) in the ovariectomized group than in the Sham group.
