The authors evaluated dental radiographs for signs of osteoporosis using four methods: fractal dimension, microdensitometry, pixel intensity and panoramic analysis of cortical thickness. The efficacy of these methods also was compared against three standard bone density measurement techniques used to diagnose osteoporosis in bones other than the jaws: quantitative computed tomography and single- and dual-photon absorptiometry. Pixel intensity was significantly more effective than the other dental methods at distinguishing between radiographs from the osteoporotic group and the control group, although fractal dimension and microdensitometry methods also were effective.
作者使用四种方法评估牙科X光片上的骨质疏松迹象：分形维数、显微密度测定法、像素强度以及皮质厚度的全景分析。这些方法的有效性还与用于诊断颌骨以外骨骼骨质疏松的三种标准骨密度测量技术进行了比较：定量计算机断层扫描以及单光子和双光子吸收测定法。在区分骨质疏松组和对照组的X光片方面，像素强度比其他牙科方法显著更有效，尽管分形维数和显微密度测定法也有效。
