The aim of this study was to evaluate radiomorphometric indices in dental panoramic radiographs in order to identify possible interrelationships between these indices and the sex and age of the patients analyzed. The study included 1287 digital panoramic radiographic images of patients that were grouped into five age groups (1 = age 17-20; 2 = age 21-35; 3 = age 36-55; 4 = age 56-69; 5 = over age 70). Two indices-cortical width at the gonion (GI) and below the mental foramen (MI)-were measured bilaterally in all panoramic radiographs. Statistical analysis was performed with Kruskal-Wallis and Mann-Whitney tests (alpha = 0.05). Results for the indices measurements showed significant differences among patient age groups of both sexes, considering that groups 4 and 5 presented lower values for the cortical width of both indices. The present paper supports the role of sex- and age-related changes in mandibular radiomorphometric indices in identifying skeletal osteopenia.
本研究的目的是评估牙科全景X线片中的放射形态计量学指标，以确定这些指标与所分析患者的性别和年龄之间可能存在的相互关系。该研究纳入了1287例患者的数字化全景X线影像，这些患者被分为五个年龄组（1组=17 - 20岁；2组=21 - 35岁；3组=36 - 55岁；4组=56 - 69岁；5组=70岁以上）。在所有全景X线片中双侧测量两个指标——下颌角皮质宽度（GI）和颏孔下方皮质宽度（MI）。采用Kruskal - Wallis检验和Mann - Whitney检验进行统计分析（α = 0.05）。指标测量结果显示，考虑到4组和5组两个指标的皮质宽度值较低，两性患者年龄组之间存在显著差异。本文支持下颌骨放射形态计量学指标中与性别和年龄相关的变化在识别骨骼骨质减少方面的作用。
