Sickle cell disease (SCD) can cause osteoporotic changes in the jaw bones. In this study, it was aimed to evaluate possible bone changes using fractal analysis (FA) and morphometric analyses in dental panoramic radiographs of children and adolescents diagnosed with both homozygous and heterozygous forms of SCD.
Sixty-five individuals (33 SCD, 32 controls) aged 6-17 years were included in the study. Four separate areas of interest (ROI) were selected for the right and left sides of all panoramic radiographs, and the FA value of the ROIs was calculated. Mandibular cortical width (MCW), panoramic mandibular index (PMI) and mandibular cortical index (MCI) and were evaluated. Data were statistically analyzed and p < 0.05 was accepted for statistical significance.
Fractal values of right and left ROI1 (the center of the mandibular angle.) and ROI4 (the cortical bone), and right ROI2 (the middle of the mandibular ramus) were statistically lower in the case group (p < 0.05). Right ROI2 and ROI4 fractal values of individuals in the case group were lower than those on the left side (p < 0.05). While MCI categories did not differ from the case-control group (p > 0.05), PMI and MCW values were lower in the case group (p < 0.05). All evaluated parameters did not differ according to age and gender (p > 0.05).
The results of this study showed that SCD affects the mandible. FA, MCW and PMI parameters can be used to detect early osteoporotic changes in the disease.
镰状细胞病(SCD)可导致颌骨骨质疏松改变。本研究旨在通过对诊断为纯合子和杂合子 SCD 的儿童和青少年的牙全景片进行分形分析(FA)和形态计量分析,评估可能的骨变化。
本研究纳入了 65 名年龄在 6-17 岁的个体(33 名 SCD,32 名对照)。所有全景片的右侧和左侧均选择 4 个感兴趣区域(ROI),计算 ROI 的 FA 值。评估下颌皮质宽度(MCW)、全景下颌指数(PMI)和下颌皮质指数(MCI)。对数据进行统计学分析,p<0.05 为统计学显著差异。
右侧和左侧 ROI1(下颌角中心)和 ROI4(皮质骨)以及右侧 ROI2(下颌支中部)的分形值在病例组中明显较低(p<0.05)。病例组中右侧 ROI2 和 ROI4 的分形值低于左侧(p<0.05)。虽然 MCI 类别与病例对照组无差异(p>0.05),但病例组的 PMI 和 MCW 值较低(p<0.05)。所有评估参数均与年龄和性别无关(p>0.05)。
本研究结果表明,SCD 影响下颌骨。FA、MCW 和 PMI 参数可用于检测疾病早期的骨质疏松变化。
