The Ovariectomized Rat as a Model for Studying Alveolar Bone Loss in Postmenopausal Women

Figure 6

Landmarks to define ROI of alveolar bone at molar 1 (M1). M1 in its bony socket (left) with the distance between the cementoenamel junction and bone crest (green) and the mandibular canal (orange). In a model of M1 with the bony socket removed (right) the alveolar bone of the interradicular septum (purple) is superior to the alveolar bone (red) between the incisor (blue) and the apices of the mesial and distal roots (image by B. Johnston).
