老年人中重度牙周炎相关因素的分析

Relative factors affecting moderate to advanced periodontitis in elderly patients

目的探讨老年人中重度牙周炎发生的相关因素，为老年人牙周炎的预防和控制提供依据。方法采用1：1匹配的病例对照研究方法，选择老年中重度牙周炎患者100例为患病组，非牙周炎患者100例为对照组。采用SPSS11．5统计软件进行条件Logistic回归单因素及多因素分析。结果口腔卫生指数、牙齿磨耗程度、龋齿补牙数、不良修复体、吸烟、系统性疾病和负性生活事件7个因素与老年人中重度牙周炎的发生有关，其OR及OR95％CI分别是1．277（1.149～1．420）、0．286（0．144～0．569）、0．816（0．690～0．965）、3．165（1．047～9．569）、2．753（1.095～6．923）、2．417（1．043～5．606）和2．655（1．124～6．316）。结论口腔卫生指数、不良修复体、吸烟、系统性疾病和负性生活事件可能为老年中重度牙周炎发生的危险因素；牙齿磨耗程度和龋齿补牙数可能为老年中重度牙周炎发生的保护因素。

Objective To investigate the relative factors of moderate to advanced periodontitis in elderly people and provide the preventing and controlling basis for them. Methods The 1 ： 1 pairedcase-control study, 100 patients and 100 controls were chosen. SPSS11. 5 statistic software was used to analyze single and multiple logistic regressions. Results Through single and multiple logistic regressions, oral hygiene status, tooth attrition, decayed filled tooth, bad prosthesis, smoking, systemic disease and negative affairs showed significantly independent association with moderate to advanced periodontitis in elderly people. Their OR and OR95%CI were 1. 277（1. 149～1. 420） ,0. 286 （0. 144～0. 569）, 0. 816 （0. 690 ～ 0. 965）, 3. 165 （1. 047 ～ 9. 569）, 2. 753 （1. 095 ～ 6. 923）, 2. 417 （1. 043～5. 606）, 2. 655 （ 1. 124 ～ 6. 316） respectively. Conclusions The oral hygiene status, bad prosthesis, smoking, systemic disease, negative affairs are probably the dangerous factors for elderly people＇s periodontitis, while the tooth attrition and decayed filled tooth are probably the protective factors.
