Introduction: Mandibular alveolar bone appears to be particularly sensitive to local factors compared to other skeletal sites. In growing rats, occlusal hypofunction leads to a dramatic decrease of the alveolar bone microarchitecture. Intra-radicular bone surrounding teeth is a specific functional area with a high bone turnover. We hypothesized that the mechanical loading of the alveolar process during mastication may play a role in the preservation of the alveolar bone microa...

Context: An increase in bone marrow adiposity (BMA) is usually described in anorexia nervosa (AN) patients and in calorie restriction models. This induced BMA could be involved in the development of the osteoporosis often described in AN. However, BMA increase is not always observed and could be depending on the severity of the deficit.We previously developed the separation-based anorexia mouse model (SBA)1 (Ethical approval CEEA #022012).
