目的探讨绝经后妇女下颌骨全景x线片上的一些测量值是否与低骨密度有关。方法对122例50岁以上妇女的口腔全景x线片及骨密度检查资料进行分析。采用双能x线骨密度仪测量腰椎和股骨近端骨密度。测量下颌颏孔下皮质骨厚度、下颌牙槽骨吸收率及下颌全景指数。结果下颌骨皮质厚度和下颌牙槽骨吸收特异性最高（腰椎：89.8% vs . 73.5%，股骨近端：83.6% vs . 71.2%）。下颌全景指数显示灵敏度最高（腰椎43.8%，股骨近端40.8%）。即使在激素治疗、吸烟、绝经年龄和体重指数调整后，下颌骨皮质厚度与骨密度之间的相关性仍具有统计学意义（P = 0.04）。结论全景式x线摄影对低骨密度患者有一定的诊断价值。
ObjectiveThe aim of this study was to investigate whether some mandibular measurements on panoramic radiographs are associated with low bone mineral density in postmenopausal women. MethodsA sample of 122 panoramic dental radiographs and bone density tests from women 50 years or older were examined. Bone mineral density was measured in the lumbar spine and proximal femur regions through dual-energy x-ray absorptiometry. The mandibular cortical bone thickness below the mental foramen, mandibular alveolar bone resorption, and panoramic mandibular index were measured. ResultsThe mandibular cortical thickness and mandibular alveolar bone resorption showed the highest specificity (lumbar spine: 89.8% vs 73.5%, proximal femur: 83.6% vs 71.2%, respectively). The panoramic mandibular index demonstrated the highest sensitivity (lumbar spine: 43.8%; proximal femur: 40.8%). The association between the mandibular cortical thickness and bone mineral density was statistically significant even after adjustment for hormonal treatment, smoking, age at menopause, and body mass index (P = 0.04). ConclusionsIt is suggested that panoramic radiography may be useful for confirming individuals who present with low bone mineral density.
