Abstract：
BACKGROUND: Osteoporosis is a disease characterized by low bone mass and microarchitectural deterioration of bone tissue, leading to bone fragility, and enhanced susceptibility to fractures. Dental radiographs, especially panoramic images, have been used to predict bone mineral density. A number of indices, (mandibular cortical index [MCI], mandibular cortical width [MCW], and panoramic mandibular index [PMI]) have been developed to assess and quantify the quality of mandibular bone mass and to observe the signs of resorption.
OBJECTIVE: The objectives of the study were to assess mental index (MI), MCW index, and PMI with bone density in identifying risk group for osteoporosis and also to investigate influence of age and gender on MI, MCI, and PMI.
METHODS: After obtaining consent, details regarding age, gender, systemic health status, and oral parafunctional habits were recorded in each patient. Then a digital panoramic radiograph was taken. The image thus obtained was subjected to calibrations and morphometric analysis using Digora version 2.7. The obtained values of indices were compared with the mean values of indices, to evaluate subjects whether they are prone to osteoporosis or not. The obtained information was subjected to statistical analysis for the significance of the parameters.
RESULTS: Data analysis showed that calibration indices were highly significant in the assessment of risk group for osteoporosis than noncalibration index. The subjects at a higher risk for development of osteoporosis were old-aged adults with higher prevalence being reported in women compared to male subjects.
CONCLUSIONS: In conclusion, our results suggest that higher percentage of subjects with undetected decreased bone mineral density may be identified based on trained general dental practitioners analyses of their panoramic radiographs using simple screening analytical calibration MI and MCI.

摘要：
背景：骨质疏松症是一种以低骨量和骨组织微结构退化为特征的疾病，导致骨骼脆弱，和增加对骨折的敏感性。牙科X光片,尤其是全景图像，已用于预测骨密度。一些指数，（下颌皮质指数[MCI]，下颌皮质宽度[MCW]，和全景下颌指数[PMI]）已被开发用于评估和量化下颌骨量的质量并观察吸收的迹象。
目的：本研究的目的是评估心理指数（MI），MCW指数，和骨密度的PMI在确定骨质疏松症的风险组，也调查年龄和性别对MI的影响，MCI和PMI。
方法：获得同意后，关于年龄的细节,性别,全身健康状况，记录每位患者的口腔功能异常习惯。然后拍摄了数字全景射线照片。使用Digora版本2.7对由此获得的图像进行校准和形态测定分析。将获得的指标值与指标的平均值进行比较，评估受试者是否容易患骨质疏松症。对获得的信息进行参数显著性的统计分析。
结果：数据分析显示，校正指标在评估骨质疏松风险组时比非校正指标有高度显著性。患骨质疏松症风险较高的受试者是老年成年人，据报道，女性患病率高于男性受试者。
结论：结论：我们的结果表明,根据训练有素的普通牙科医师使用简单的筛查分析校准MI和MCI对其全景X线照片的分析,可以识别出更高百分比的未检测到骨矿物质密度降低的受试者.
