目的 研究健康人下颌骨与全身骨密度的相关性.方法 选择中国北方健康志愿者221名,分别将不同性别的志愿者按年龄分为6组,即≥20岁(男21人、女23人)、≥30岁(男20人、女21人)、≥40岁(男21人、女22人)、≥50岁(男20人、女21人)、≥60岁(男16人、女15人)、≥170岁(男11人、女10人).从每人下颌骨颏部及双侧下颌角各选10个感兴趣区,用双能X线骨密度仪测量骨密度值,同时测量腰椎(L2-L4);并行统计学分析.结果 该人群的下颌骨颏部的骨密度值为(1.310 9±0.035 5)g/cm2,左下颌角的骨密度值(1.048 9±0.013 7)g/cm2,右下颌角的骨密度值(1.054 7±0.014 1)g/cm2,腰椎(L2-L4)的骨密度值(1.1211±0.0172)g/cm2.男女之间下颌角、腰椎的骨密度比较,差异有统计学意义(t(左)=2.017 5,t(右)=2.446 9,P<0.05).50岁以后下颌角、腰椎的骨密度明显减低.结论 下颌骨与腰椎的骨密度密切相关,下颌骨可以作为测量全身骨密度的一个敏感部位进行骨质疏松的预测.

Objective To measure the bone mineral density(BMD)of mandible and investigate the relationship between mandible and the whole body skeleton BMD.Methods Healthy volunteers were recruited in north China,which were divided into 6 groups by age:≥20,≥30,≥40,≥50,≥60 and ≥70 years older,10 male and 10 female in each group.Dual-energy X-ray absoptiometery(DXA)was used to measure the BMD of the lumbar spine,the mentum of mandible and the mandibular angle.The results were analyzed statistically.Results The mineral density(MD )of the mentum was(1.310 9 ±0.035 5)g/cm2,the left mandibular angle(1.048 9 ± 0.013 7)g/cm2,the right mandibular angle (1.0547 ±0.014 1)g/cm2,the lumbar spine(L2-L4)(1.121 1±0.017 2)g/cm2.There was a significant difference in mandibular angle and lumbar MD between men and women(P<0.05).The MD of mandibular angle and lumbar spine decreased significantly after 50 years of age.Conclusions The normal BMD of the mandibular mentum,mandibular angles and lumbar spine is obtained.The BMD of the mandibular angles is closely related to that of the lumbar spine.Mandible can be an appropriate measurement site in the evaluation of skeleton BMD status for the forecast of osteoporosis.
