摘　　要：目的：研究中老年人骨密度降低及骨质疏松与牙周炎之间的关系。方法：选取122名进行体格检查的中老年人,女104名,男18名,进行骨密度测定及口腔检查。根据骨密度值（T值）分为观察组（T〈-1.0）与对照组（T〉-1.0）。根据附着丧失（CAL）、余留牙数目分为轻、中、重度牙周炎。运用统计学软件进行骨密度与慢性牙周炎分级间的χ~2检验,并与牙周附着丧失进行相关性分析。结果：观察组较对照组,中、重度牙周炎的患病率显著增高（χ~2=4.41,P〈0.05）。中老年人群的骨密度值与CAL值显著负相关（tr=-3.88,P〈0.001）,即随着骨密度降低,CAL呈增加趋势。结论：中老年人群中,骨量减少及骨质疏松与慢性牙周炎的严重程度相关;骨密度降低可能是中老年人中、重度慢性牙周炎进展的促进因素。Objective： To study the correlation between osteoporosis and chronic periodontitis in middle-aged and elderly people. Method： The oral condition of 122 individuals who had bone mineral density examination was examined. They were divided into observation group and control group according to the bone density. T score of the observation group was less than-1.0, the control group was more than-1.0. The severity of periodontitis was divided into mild, moderate and advanced according to clinical attachment loss and number of remaining teeth. The chi-square test was made between bone density and severity of periodontitis. Correlation analysis was made between bone density and clinical attachment loss. Result： In observation group, the rate of moderate and advanced chronic periodontitis was significantly higher than that in control group.（χ2=4.41, P0.05）. There was significant correlation between bone density and severity of periodontitis（χ2=4.41, P 0.05）. There was negative correlation between bone density and clinical attachment loss（tr=-3.88, P 0.001）. As the declining of bone density, the severity of clinical attachment loss had an increasing tendency. Conlusion： There was correlation between bone density and severity of chronic periodontitis in middle-aged and elderly people. Osteopenia and osteoporosis may be a risk factor for chronic periodontitis.
