【摘要】 目的：探讨老年中重度牙周炎的相关因素，为临床上老年牙周炎的预防和控制提供依据。方法：采用病例对照研究，病例组100例，对照组100例，病例和对照按照年龄、性别、文化程度、居住地进行配对。所有研究对象均进行面对面问卷调查，并进行口腔临床检查。分析整理资料，应用logistic回归模型进行单因素、多因素分析及因素间的联合作用分析。结果：单因素分析有15个因素与老年中重度牙周炎相关。多因素分析显示：老年中重度牙周炎发病的危险因素为口腔卫生差、不良修复体、吸烟、系统性疾病和负性生活事件，其OR值及95％可信区间分别为1.277（1.149,1.420），3.165（1.047,9.569），2.753（1.095,6.923），2.417（1.043,5.606）和2.665（1.124,6.316）。此外，患中重度牙周炎的老年患者牙齿磨耗程度显著低于对照组，龋补牙数显著低于对照组，其OR值及95％可信区间分别为0.816（0.690,0.965），0.286（0.144,0.569）。结论：预防和控制老年中重度牙周炎，应加强全民口腔健康教育宣教，改善口腔卫生状况，积极倡导戒烟，作为口腔医生应坚决杜绝不良修复体，重视牙周炎与系统性疾病的关系，并积极减少负性生活事件对老年人的影响。更多还原

【Abstract】 Objective To investigate the relative factors of moderate to advanced periodontitis in elderly people and provide the preventing and controlling basis for them . Methods In a pair-matched case-control study, 100 patients and 100 controls were matched according to age, sex, education degree and living area. All the cases were investigated face-to-face and were checked their oral cavity clinically. Data were made analysis of the unvaried and multivariate and combined effect.Result In multiple logistic regressions: smoking, oral hygiene status, bad prosthesis, systemic disease, negative affairs, tooth attrition and decayed filled tooth. Showed significantly independent association with moderate to advanced periodontitis in elderly people, the odds ratio OR and OR 95% CI were2.753(1.095,6.923),1.277(1.149,1.420),3.165(1.047,9.569),2.417(1.043,5.606),2.665(1.124,6.316),0.816(0.690,0.965) ,0.286(0.144,0.569).Conclusion It was suggested that we should strengthen oral health instruction, stop bad prosthesis as a dentist advocate giving up smoking furthermore, we also should think much of the old people’s systemic disease and also their social mental problems.更多还原
