The researchers studied the dental status of 28 post-menopausal women with normal bones and 28 who were taking bisphosphonate therapies for osteoporosis for at least two years or more. Women between 51 and 80 years old received computerized tomography (CT) of their jaws as well as a complete periodontal examination of plaque, bleeding and bone loss. Participants followed the ADA guidelines related to brushing, flossing and visited the dentist twice a year.

The researchers found that both groups had high levels of bacterial plaque, which could increase the risk of bone loss in the mandibular bone or reverse bone mass through drug therapies. After menopause, women at risk for osteoporosis also have the risk of gum disease (periodontal disease), which affects the bony anchorage of the teeth. Over time, dental plaque that accumulates in the teeth can lead to periodontal disease.

Researchers emphasize that bone diseases and gum diseases are different diseases. Women who ingest bisphosphonates also need to remove dental plaque to keep their jaw bones strong and healthy.

Consult your dentist for recommendations about brushing, flossing and dental visits. He or she will be able to recommend the oral care regimen that suits your needs and health status.
