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 relationship between lower bone mineral density (BMD) and osteoporosis in the middle-aged and elderly patients with periodontitis. Methods: 122 middle-aged and elderly women, 104 women and 18 men were selected for physical examination and bone mineral density measurement and oral examination. According to the BMD values (T value), the patients were divided into observation group (T <-1.0) and control group (T> -1.0). According to the loss of attachment (CAL), the number of remaining teeth is divided into light, moderate and severe periodontitis. Statistical software was used to test χ ~ 2 between bone mineral density and chronic periodontitis grading, and the correlation analysis was carried out with the loss of periodontal attachment. Results: The prevalence of moderate and severe periodontitis in observation group was significantly higher than that in control group (χ ~ 2 = 4.41, P <0.05). The middle-aged and elderly population had a significantly negative correlation with the CAL value (tr = -3.88, P <0.001), indicating that CAL increased with the decrease of BMD. CONCLUSIONS: In the middle-aged and elderly population, osteopenia and osteoporosis are associated with the severity of chronic periodontitis. Decreased bone mineral density may be a contributing factor in the progression of moderate and severe chronic periodontitis in the elderly.
