Relative Skeletal Effects in Different Sites of the Mandible With the Proximal Tibia During Ovariectomy and the Subsequent Estrogen Treatment

A microcomputed tomography scan of a cross-section of the mandible (a) and three-dimensional reconstruction (b). (a) The blue line represents volume of interest. The red area reveals the trabecular bone in the mandible. (b) a: The basal bone below the molars, one of the biomechanical tested area; b: the incisor alveolar; c: the site 1 mm behind the third mandibular molar, another site for biomechanical analysis.

Positive correlations between the overall/tooth-specific mandible and the proximal tibia in trabecular bone structural parameters measured by microcomputed tomography. (a) Bone surface/bone volume (BS/BV) and (b) Trabecular thickness (Tb.Th.) between the mandible and the proximal tibia. (c) BS/BV, (d) Tb.Th., and (e) Trabecular separation (Tb.Sp.) between the mandible around the mandibular–first-molar, and the proximal tibia.

Significant correlation of the biomechanical strength between the basal bone of the mandible and the proximal tibia.

Figure 4. The panoramic view (a) and the sagittal views of the cone beam computerized tomography images showed very low bone density and HU values in both regions of the right first molar (b) and the left first molar (c).
