The aim was to test for correlations of 7 panoramic radiomorphometric indices with lumbar spine and hip bone mineral densities (BMDs) and to test the accuracy of these indices for predicting osteoporosis and a T-score < or =-2.0.
Mandibular cortical indices, simple visual estimations of cortical widths, mental and antegonial indices, antegonial depth, gonial and antegonial angles, and BMD were measured in 351 postmenopausal women.
Associations were demonstrated between BMDs, qualitative indices, and cortical measurements. In the case of severely eroded mandibular cortices, the odds ratio (OR) for osteoporosis (according to the World Health Organization criteria) was 4.82 and the OR for a T-score < or =-2.0, the threshold to begin treatment, was 10.87. In the case of very thin mandibular cortices, the ORs were 8.02 and 5.46 for osteoporosis and a T-score < or =-2.0, respectively. The mental index cutoff for osteoporosis was 3.15 mm.
Antegonial indices and gonial angles cannot be used as osteoporosis predictors. The most accurate indices were the mental index, mandibular cortical index, and visual estimation of cortical width.
本研究旨在检测7项全景放射形态测量指标与腰椎和髋部骨密度（BMD）之间的相关性，并测试这些指标预测骨质疏松症以及T值≤ -2.0的准确性。
对351名绝经后女性测量下颌骨皮质指标、皮质宽度的简单视觉估计、颏孔和下颌角前切迹指标、下颌角前切迹深度、下颌角和下颌角前切迹角度以及骨密度。
证明了骨密度、定性指标和皮质测量之间存在关联。在下颌骨皮质严重侵蚀的情况下，骨质疏松症（根据世界卫生组织标准）的优势比（OR）为4.82，而开始治疗的阈值T值≤ -2.0的OR为10.87。在下颌骨皮质非常薄的情况下，骨质疏松症和T值≤ -2.0的OR分别为8.02和5.46。骨质疏松症的颏孔指数临界值为3.15毫米。
下颌角前切迹指标和下颌角不能用作骨质疏松症的预测指标。最准确的指标是颏孔指数、下颌骨皮质指数和皮质宽度的视觉估计。
