摘要
目的 探讨骨质密度与牙齿的关系。方法 骨密度仪随机检测 833名 35岁以上年龄组正常人群的桡骨骨质密度 (BMC/ BW) ,含钙水平 (BMC) ,且仔细检查每个人口腔余留牙、松动牙数目 ,龋齿情况。结果 45岁以上年龄组女性全身含钙水平 ,桡骨骨质密度开始下降 ,且逐年按不同程度递减 ,并在 5 5岁以后余留牙数目减少 ,松动牙数目增多 ,但龋患率无显著性差异 ;5 5岁以上男性年龄组全身含钙水平 ,骨质密度开始下降 ,6 5岁以后余留牙数目减少 ,松动牙数目增多 ,龋患率无显著性差异 ,而且骨质密度与口腔余留牙数目呈正相关 (γ女 =0 .95 87,γ男 =0 .95 0 5 )。结论 中老年人在注意口腔常规保健与治疗的同时 ,还应密切注意全身钙质水平的变化 ,及时补钙 ,对防止牙齿松动与脱 ,落可能有临床意义。
WT5”BZ]Aim To study about relationship between skeletal bone density and tooth. Methods BMD and BMC of the distal radius of 833 healthy people over 35 years old were measured randomly by single photon absorptiometry (BMD 400E), At the same time their number of teeth present, teeth luxated, teeth decayed were investigated carefully respectively. Results BMD and BMC of the distal radius of female group over 45 years old decrease gradually every year in different degrees, the number of teeth present decrease and the number of teeth luxated increase in female group over 55 years old. But no significant difference exists in caries incidence between every decade; On the other hand, In male group over 55, BMD、BMC and the number of teeth present decrease gradually, but the number of teeth luxated increase. No significant difference exists in caries incidence between every decade. In female and male group, bone density correlate significantly with the number of teeth present ( γ male =0.9505 γ female =0.9587 P <0.01). Conclusion They must pay attention to BMD and BMC while they take dental care and normal treatment. It may be very important for old people to prevent teeth from luxating. [WT5”HZ]
