Sažetak
The purpose of this study was to determine the relative usefulness of mandibular bone mineral density (BMD) measurements on dental panoramic radiographs in the diagnosis of patients with postmenopausal osteoporosis amongst 52 postmenopausal women, aged 62 to 78 years, attending for routine dental treatment. Skeletal BMD was measured for the lumbal spine and femoral neck, using dual energy X-ray absorptionetry. The WHO criterial for Caucasian women were used for osteopenia (t-score between -1 and -2.5 standard deviations below the peak bone mass) and osteoporosis (t-score more than -2.5 standard deviations bolow that mean). Patients were classed as having postmenopausal osteoporosis if they had t-scores of >-2.5 at either or both sites. The patients with osteopenia received Ca and vitamin D therapy and the patients with postmenopausal osteoporosis received alendronate therapy (Fosamax, 70 mg/weekly) during one year. Each patient received a dental panoramic radiograph. Using the copper stepwedge, mandibular BMD was measured below the mental foramen and on the two different sights on the lower cortical border of the mandible. The mandibular BMD measurements were expressed as the equivalents of the actual stepwedge thicknesses. When the logistic regression model included BMD measurements, all four variables were significant predictors of postmenopausal osteoporosis (p<0.05). ROC analysis showed that for the BMD1 area under the curve was 0.73 (SE=0.08, CI=0.56-0.88), for BMD2 it was 0.70 (SE=0.08, CI=0.53-0.87), for BMD3 it was 0.94 (SE=0.03, CI=0.88-1.00) and for BMD4 it was 0.78 (SE=0.06, CI=0.65-0.91). The mandibular BMD values measured on panoramic radiographs are a significant factor in predicting postmenopausal osteoporosis.
