A new study in the June 2007 Journal of Periodontology found postmenopausal women infected with four species of periodontal bacteria were more likely to have oral bone loss, even after adjusting for smoking, age and income.

Osteoporosis is a common metabolic bone disease characterized by low bone mass and fragility, especially for postmenopausal women. It can also occur in men and is commonly associated with a decrease in bone mineral density.

The study supports the findings of previous research that identified an association between postmenopausal osteoporosis and tooth loss, along with alveolar bone loss.

Patients should be aware that osteoporosis has several modifiable risk factors, including smoking, inadequate dietary calcium and estrogen deficiency. Anyone suspected of being at risk for osteoporosis - based on medical history, including risk factors, and results of clinical and X-ray examination - should refer to their primary-care physician for a complete health assessment.
