摘要
目的研究老年性骨质疏松症患者下颌骨骨密度的改变,探讨下颌骨骨密度改变与全身骨密度改变的相关性。方法对40例老年性骨质疏松症患者(A组)、40名非骨质疏松症老年志愿者(B组)和40名青年健康志愿者(C组)摄取标准化数字曲面体层X线片;应用计算机图像处理软件对标准化数字曲面体层X线片的下颌骨下缘皮质骨厚度、曲面体层下颌指数、牙槽骨骨密度、牙槽骨骨高度进行测量。使用双能X线吸收骨密度仪测量腰椎及髋关节骨密度。结果A组下颌骨下缘皮质骨厚度(3.57±0.82)与全身骨密度显著相关(P〈0.05)。A组与C组标准化数字曲面体层X线片测量指标(下颌骨下缘皮质骨厚度、曲面体层下颌指数、牙槽骨骨密度、牙槽骨骨高度)差异均具有统计学意义(P〈0.05);A组下颌骨下缘皮质骨厚度(3.57±0.82)与曲面体层下颌指数(O.29±0.06)与B组(下颌骨下缘皮质骨厚度:4.07±0.75,曲面体层下颌指数:0.32±0.07),差异有统计学意义(P〈0.05);B组牙槽骨骨密度(105.40±20.48)与牙槽骨骨高度(10.42±1.82)与C组(牙槽骨骨密度:117.10±22.23,牙槽骨骨高度:11.69±1.63)差异具有统计学意义(P〈0.05)。结论老年性骨质疏松症患者下颌骨下缘皮质骨丢失明显,骨质疏松症对健康牙槽骨没有显著影响,其牙槽骨骨丢失主要为一种增龄性改变。
Objective To investigate the mandibular bone mineral density(BMD) change of senile osteoporosis patients and the relationship between the mandible bone loss and systemic bone loss. Methods Forty senile osteoporotic patients( group A), 40 non-osteoporesis control elders( group B) and 40 healthy youths(group C) were included in this study. Standard digital panoramic tomography (SDPTG) was taken for each participant. Cortical width (CW), panoramic mandibular index (PMI), alveolar bone density and alveolar bone height were measured on the SDPTG. Lumbar and hip BMD were measured with dual energy X-ray absorptionmetry (DXA). Results Close relationship was found between CW (3.57 ±0. 82) and systemic BMD for osteoporosis patients (P 〈 0. 05 ). All the SDPTG indices including CW, PMI, alveolar bone density and alveolar bone height were different for osteoporesis patients from the healthy youths (P 〈 0. 05). The osteoporosis patients had thinner CW(3. 57 ±0. 82) and smaller PMI(0. 29 ±0. 06) than nonosteoporosis control eiders ( CW: 4.07 ± 0. 75, PMI: 0. 32 ± 0. 07, P 〈 0.05 ). The alveolar bone density ( 105.40 ± 20. 48 ) and alveolar bone height ( 10. 42 ± 1.82 ) of the non-osteoporosis control elders reduced compared with the healthy youths (alveolar bone density : 117. 10 ± 22. 23,alveolar bone height: 11.69 ± 1.63, P 〈 0.05 ). Conclusions The senile osteoporotic patients had significant mandibular cortical bone loss.
