To determine whether the bone mineral density (BMD) of the mandibular cortex is correlated with an ordinal classification of the morphology of the inferior cortex on panoramic radiographs.
The cortical BMD of the mandible was measured by single-energy quantitative computed tomography at two sites: (1) buccally and distally from the mental foramen, (2) lingually and distally from the mental foramen. The morphology of the mandibular cortex was assessed on panoramic radiographs, and classified into three groups.
The severity of the changes in the mandibular cortex was significantly related to the BMD of the buccal cortex (ANOVA: p = 0.002).
The use of an ordinal classification of the mandibular cortex on panoramic radiographs may be helpful for general dental practitioners in the assessment of the local quality of the cortical bone.
确定下颌骨皮质骨矿物质密度（BMD）与全景X线片上下颌骨下缘皮质形态的序数分类是否相关。
通过单能定量计算机断层扫描在下颌骨的两个部位测量皮质骨密度：（1）颏孔颊侧和远中侧；（2）颏孔舌侧和远中侧。在全景X线片上评估下颌骨皮质的形态，并分为三组。
下颌骨皮质变化的严重程度与颊侧皮质骨密度显著相关（方差分析：p = 0.002）。
在全景X线片上对下颌骨皮质进行序数分类，可能有助于普通牙科医生评估皮质骨的局部质量。
