Abstract

Introduction

This study aims to evaluate the radiomorphometric indices and fractal dimension (FD) analysis on the digital panoramic radiography (DPR) of patients with Systemic Lupus Erythematosus.

Materials and methods

This cross-sectional retrospective study included a total of 64 individuals. The panoramic mandibular index - inferior and panoramic mandibular index - superior (PMI-i, PMI-s), gonial index (GI), mandibular cortical index (MCI), and fractal dimension (FD) analysis values for all patients were computed on digital panoramic radiographs (DPRs). The statistical analysis of the entire dataset was conducted using SPSS version 22.

Results

The age and gender distributions in the Systemic Lupus Erythematosus group were comparable to those in the control group (p > 0.05). The two groups did not exhibit statistically significant differences regarding PMI-i, PMI-s, GI, MCI, and FD analysis.

Conclusion

Our analysis revealed no significant differences in mandibular cortical and trabecular bone structure between healthy individuals and patients with Systemic Lupus Erythematosus. Given the absence of other studies on this topic, our findings necessitate further validation through the examination of clinical indicators.

应用放射形态学指标和分形维数评价系统性红斑狼疮患者骨变化。

前言：本研究旨在评价系统性红斑狼疮患者数字全景x线摄影（DPR）的放射形态指标和分形维数（FD）分析。材料和方法：本横断面回顾性研究共纳入64例个体。在数字全景x线片（DPRs）上计算所有患者的下颌全景指数-下、下颌全景指数-上（PMI-i、PMI-s）、下颌骨指数（GI）、下颌皮质指数（MCI）和分形维数（FD）分析值。整个数据集的统计分析使用SPSS 22版本进行。结果：系统性红斑狼疮组患者的年龄、性别分布与对照组比较，差异有统计学意义（p < 0.05）。两组在pmi - 1、pmi - 5、GI、MCI和FD分析方面无统计学差异。结论：我们的分析显示健康个体和系统性红斑狼疮患者的下颌皮质和骨小梁结构没有显著差异。鉴于缺乏其他关于这一主题的研究，我们的发现需要通过临床指标的检查进一步验证。
