The increasing aging population places postmenopausal women at higher risk of osteoporosis due to reduced bone mass. While Dual-Energy X-ray Absorptiometry (DXA) is the standard for measuring Bone Mineral Density (BMD), its cost and limited availability drive the need for alternative methods. Fractal Dimension (FD) analysis of trabecular bone patterns in periapical radiographs offers a cost-effective and accessible approach. This study examines FD differences in anterior and posterior mandibular regions as a potential early marker for osteoporosis in postmenopausal women.
MATERIALS & METHODS: A cross-sectional study analyzed periapical radiographs from 31 postmenopausal women with BMD and T-score data from DXA scans. FD analysis measured alveolar bone density (ABD) and D values in the anterior and posterior regions. One-way ANOVA tested regional differences, while Spearman's and Pearson's correlation assessed relationships between FD values, BMD, and T-score.
No significant differences were found between anterior and posterior ABD and D values (p > 0.05). ABD showed a significant positive correlation with BMD (r = 0.383, p < 0.05), while D values did not. The T-score correlated significantly with anterior ABD (r = -0.357, p < 0.05).
Although no significant regional FD differences were found, ABD in periapical radiographs, particularly in the anterior region, may serve as a potential indicator for osteoporosis risk in postmenopausal women.
人口老龄化加剧,绝经后女性因骨量减少而患骨质疏松症的风险更高。虽然双能X线吸收法(DXA)是测量骨密度(BMD)的标准方法,但其成本高且可用性有限,因此需要替代方法。根尖片中小梁骨模式的分形维数(FD)分析提供了一种经济有效且易于获得的方法。本研究探讨绝经后女性下颌前、后区域的FD差异,作为骨质疏松症的潜在早期标志物。
一项横断面研究分析了31名绝经后女性的根尖片,并获取了她们DXA扫描的BMD和T值数据。FD分析测量了前、后区域的牙槽骨密度(ABD)和D值。单因素方差分析测试区域差异,而Spearman和Pearson相关性分析评估FD值、BMD和T值之间的关系。
前、后ABD和D值之间未发现显著差异(p>0.05)。ABD与BMD呈显著正相关(r=0.383,p<0.05),而D值则不然。T值与前ABD显著相关(r=-0.357,p<0.05)。
虽然未发现显著的区域FD差异,但根尖片中的ABD,尤其是在前部区域,可能作为绝经后女性骨质疏松症风险的潜在指标。
