口腔全景片评价更年期妇女骨质疏松的研究

Clinical study on using oral panoramic radiographs evaluate osteoporosis of menopausal women

目的了解更年期妇女口腔数字全景片的相关颌骨骨密度(BMD)与全身BMD的关系。方法选择100例更年期妇女,测定全身BMD相关指数,同时拍摄口腔数字全景片,测定其下颌骨相对BMD、曲面体层下颌指数(PMI)、下颌骨吸收指数(MRI),对其进行统计学相关性分析。结果下颌骨相对BMD及PMI与全身BMD各指数均有相关性;MRI与腰椎BMD有相关性,但与其他全身BMD无相关性;全身BMD各指数彼此都有相关性;PMI与下颌骨相对BMD及MRI均有相关性,下颌骨BMD与MRI无相关性。结论更年期妇女颌骨BMD与其全身BMD具有相关性,其中PMI与全身BMD的相关性最高,可以作为敏感指标初步筛查更年期妇女骨质疏松的情况。

Objective This study determined the correlation between relevant indexes of the oral panoramic radiographs and the whole body bone mineral density（BMD）. Methods One hundred menopausal women were selected according to the inclusion criteria. The whole body BMD were measured, at the same time as dental panoramic radiographs were taken. Mandibular relevant BMD, panoramic mandibular index（PMI）, and mandible resorption index（MRI） were measured on the panoramics. The measured data were used for the statistical correlation analysis. Results Their mandibular relevant BMD and PMI correlate with all indices measured for their whole body BMD. MRI and lumbar spine BMD are correlated, but not with other systemic BMD. PMI correlates with the mandibular relevant BMD and MRI, but the mandibular relevant BMD does not correlate with MRI. PMI is more correlated with lumbar spine BMD than the mandibular relevant BMD and MRI. Conclusion The menopausal women mandibular BMD were closely related to their body BMD. The PMI was the most correlated with the lumbar spine BMD in the three indices of the mandibular BMD. PMI can be used as one of the sensitive indicators for screening menopause osteoporosis.
