The Urinary Fluoride Concentration and Periodontal Condition in Postmenopausal Osteoporotic Women

  • 1Department of Periodontology, College of Dentistry Chonnam National University, Institute of Dental Science, Korea.


There were few reports about the fluoride concentration in bone and osteoporotic women. This study was designed to evaluate the relationship between the urinary fluoride concentration and periodontal condition in osteoporotic old women. Twenty-eight postmenopausal women(Test group) and twenty-one premenopausal women(Control group) were examined. Bone mineral density(BMD) of lumbar spine(L2-L4) was measured by dual energy X-ray absorptiometry(DEXA). The urine samples were collected at early morning and determined with the help of a fluoride-specific electrode and Tisab-bufferd samples. The results were as follows. 1.The mean urinary fluoride concentration in test and control group showed statistically no difference. 2.The bone mineral density(BMD) of the spine in test group was significantly lower than control group(p<0.05). 3.The significant negative correlation was found between BMD level and age after menopause(p<0.001, gamma=-0.526). 4.The urinary fluoride concentration was not correlated with age, age after menopause and bone mineral density. 5.The urinary fluoride concentration was not correlated with periodontal condition.
