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.
Forty senile osteoporotic patients (group A), 40 non-osteoporosis 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 absorptiometry (DXA).
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 osteoporosis 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 non-osteoporosis control elders (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).
The senile osteoporotic patients had significant mandibular cortical bone loss.
探讨老年骨质疏松患者下颌骨骨密度（BMD）变化以及下颌骨骨质流失与全身骨质流失之间的关系。
本研究纳入40例老年骨质疏松患者（A组）、40例非骨质疏松对照老年人（B组）和40例健康青年（C组）。为每位参与者拍摄标准数字化全景断层摄影（SDPTG）。在SDPTG上测量皮质骨宽度（CW）、全景下颌指数（PMI）、牙槽骨密度和牙槽骨高度。采用双能X线吸收法（DXA）测量腰椎和髋部BMD。
骨质疏松患者的CW（3.57±0.82）与全身BMD之间存在密切关系（P<0.05）。骨质疏松患者的所有SDPTG指标，包括CW、PMI、牙槽骨密度和牙槽骨高度，与健康青年相比均有差异（P<0.05）。骨质疏松患者的CW（3.57±0.82）比非骨质疏松对照老年人更薄，PMI（0.29±0.06）更小（CW：4.07±0.75，PMI：0.32±0.07，P<0.05）。与健康青年相比，非骨质疏松对照老年人的牙槽骨密度（105.40±20.48）和牙槽骨高度（10.42±1.82）降低（牙槽骨密度：117.10±22.23，牙槽骨高度：11.69±1.63，P<0.05）。
老年骨质疏松患者存在明显的下颌骨皮质骨流失。
