[Oral osteoporosis: a review and its dental implications].

: In post-menopausal osteoporosis, lack of estrogen will affect the remodeling of the bone tissue in such a way that, in most patients with periodontitis, the amount of bone resorbed exceeds that being formed, resulting in net bone loss. Osteoporosis can be treated by a variety of methods, the hormone replacement therapy (HRT), the selective estrogen receptor modulators (SERM) and the bisphosphonates. The HRT or bisphosphonates treatments improve the clinical outcome of periodontal disease and may be an adjunctive treatment to preserve periodontal bone mass. This paper reviews the current evidence on the mechanism of periodontal breakdown after menopause and the benefit to oral health by treatments for osteoporosis.
