Osteoporosis: a possible modifying factor in oral bone loss

Abstract

There has been increasing interest in the interrelationship between systemic osteoporosis, oral bone loss, tooth loss, and risk factors for these conditions. Because the severity of alveolar bone loss increases with age, it has long been hypothesized that it may, in part, be related to systemic conditions that also predispose the patient to osteoporosis/osteopenia. The purpose of this paper is to review the risk factors for osteoporosis and periodontitis, as well as the evidence that loss of oral bone mineral may be related to systemic osteopenia. There is also evidence that therapies designed to influence systemic bone mineral density, such as hormone replacement and bisphosphonate therapy, may be associated with less tooth loss and a slower loss of alveolar bone, respectively.
