OBJECTIVE
To analyse the relationship between mandibular and general skeletal mineral status at two different postmenopausal stages.
METHODS
Using dual energy quantitative computed tomography, the mandibular and 3rd lumbar (L3) vertebral bone mineral density (BMD) were evaluated in 21 women within five years after the menopause (recent postmenopause) and 23 women more than five years after (long-term postmenopause).
RESULTS
There were significant correlations between the mandibular cortical and L3 vertebral BMD (p < 0.01) in the recent postmenopausal women and between the mandibular BMD and the trabecular BMD of L3 vertebrae (p < 0.05) in the long-term postmenopausal women.
CONCLUSION
These results suggest that the general mineral status more markedly affects the mandibular cortex in the recent postmenopausal stage and both cortical and trabecular bone in the long-term postmenopausal stage.
目的
分析两个不同绝经后阶段下颌骨与全身骨骼矿物质状态之间的关系。
方法
采用双能定量计算机断层扫描技术，对21名绝经后五年内（近期绝经）的女性和23名绝经五年以上（长期绝经）的女性的下颌骨及第三腰椎（L3）椎体骨密度（BMD）进行评估。
结果
近期绝经女性的下颌骨皮质骨与L3椎体骨密度之间存在显著相关性（p < 0.01），长期绝经女性的下颌骨骨密度与L3椎体小梁骨密度之间存在显著相关性（p < 0.05）。
结论
这些结果表明，全身矿物质状态在近期绝经阶段对下颌骨皮质的影响更为显著，而在长期绝经阶段对皮质骨和小梁骨均有影响。
