引起牙周病相关影响因素的病例对照研究

目的探讨影响牙周病的相关因素及预防对策。方法将134例牙周病患者作为观察组，选择同期134例健康体检人群作为对照组．比较两组性别、年龄、教育程度、经济收入、吸烟、牙周疾病知识、自身口腔健康状况评价、定期接受口腔检查、近2个月内是否存在精神压力、营养不良、糖尿病方面的差异。结果单因素分析显示，9个因素差异均有统计学意义（均P〈0．05），Logistic回归分析显示影响牙周病危险因素主要是缺少牙周病知识（OR=3．70）、吸烟（OR=3．39）、营养不良（OR=3．01）、糖尿病（OR=2．78）。结论牙周病是多因素疾病，预防需从多方面考虑，防止病情发生和发展：开展口腔卫生宣教、戒烟、合理调整营养、控制血糖水平。
