OBJECTIVE
The aim of this study was to assess relationships between panoramic indexes, bone mineral density (BMD), and osteoporotic fractures in men >60 years old.
STUDY DESIGN
Body height and weight, body mass index, lumbar spine and hip BMD, and the presence of osteoporotic fractures were determined in the 127 studied men. Dental panoramic radiographs (DPRs) were used for measuring mandibular cortical indexes.
RESULTS
BMDs were lower in patients with thinning and resorption of mandibular cortex. No association was found between mandibular indexes and the presence of osteoporotic fractures. In a forward stepwise logistic regression model, the odds of having a T score ≤-2.5 was increased by 1.97 times for every 1-mm reduction in average mandibular cortical width.
CONCLUSIONS
DPRs could show pronounced thinning of the inferior mandibular cortices in men >60 years old. However, there was no apparent association between vertebral fragility fractures and the appearance of mandibular cortex in elderly men.
目的
本研究旨在评估60岁以上男性全景指数、骨矿物质密度（BMD）和骨质疏松性骨折之间的关系。
研究设计
对127名研究对象测定身高、体重、体重指数、腰椎和髋部骨密度以及骨质疏松性骨折情况。使用牙科全景X线片（DPR）测量下颌骨皮质指数。
结果
下颌骨皮质变薄和吸收的患者骨密度较低。未发现下颌骨指数与骨质疏松性骨折之间存在关联。在向前逐步逻辑回归模型中，下颌骨皮质平均宽度每减少1毫米，T值≤ -2.5的几率增加1.97倍。
结论
DPR可显示60岁以上男性下颌骨皮质明显变薄。然而，老年男性椎体脆性骨折与下颌骨皮质外观之间无明显关联。
