The edentulous ovine diastema represents a suitable region for implantological research. Due to distinctive embryonic origin and mechanical loading, the edentulous diastema may respond differently to osteoporosis than tooth-bearing areas. To test this assumption, we subjected geriatric sheep to ovariectomy, calcium-/vitamin-D-restricted diet, and methylprednisolone administration. Adult control sheep remained untreated. Structural parameters and bone mineral density were determined by microcomputed tomography and conventional computed tomography, respectively. We report that the trabecular microstructure in the diastema was preserved from catabolic changes. In contrast, the premolar maxillary region of osteoporotic sheep had diminished trabecular bone mineral density, with the corresponding structural deteriorations. These results suggest that maxillary trabecular bone of the edentulous diastema does not respond to catabolic changes which occur in the tooth-bearing area in osteoporosis. Our findings imply that regional anatomic domains must be considered in the planning of pre-clinical studies, taking osteoporotic changes into account.

AbstractOsteoporosis, a disease characterized by low bone mass and alterations of bone microarchitecture, leading to an increased risk for fragility fractures and, eventually, to fracture; is associated with an excess of mortality, a decrease in quality of life, and co-morbidities. Bone mineral density (BMD), measured by dual X-ray absorptiometry (DXA), has been the gold standard for the diagnosis of osteoporosis. Trabecular bone score (TBS), a textural analysis of the lumbar spine DXA images, is an index of bone microarchitecture. TBS has been robustly shown to predict fractures independently of BMD. In this review, while reporting also results on BMD, we mainly focus on the TBS role in the assessment of bone health in endocrine disorders known to be reflected in bone.
