Zoledronate effects on systemic and jaw osteopenias in ovariectomized periostin-deficient mice.

Osteoporosis and periodontal disease (PD) are frequently associated in the elderly, both concurring to the loss of jaw alveolar bone and finally of teeth. Bisphosphonates improve alveolar bone loss but have also been associated with osteonecrosis of the jaw (ONJ), particularly using oncological dose...

Zol 1M and Zol 1W did not reactivate inflammation nor increase fibrous tissue in the bone marrow of the jaw, whereas the distance between the root and the enamel of the incisor (DRI) remained high in Postn(-/-) vs Postn(+/+) confirming latent inflammation and lack of crestal alveolar bone.
