目的评价口腔卫生宣教和指导在老年人牙周治疗中的作用。方法选择2008年6月至2009年6月肇庆市第一人民医院口腔科轻、中度牙周病患者100例,随机分为试验组和对照组,各50例。在牙周治疗过程中对试验组患者进行口腔卫生宣教和指导。在初诊及之后1周、3个月、6个月、1年时分别检测两组患者的菌斑指数-QT改良法(PLI-QT)和牙龈指数(GI)。结果试验组与对照组初诊时的PLI和GI指数差异无统计学意义(P>0.05);治疗后两组PLI和GI指数差异均有统计学意义(P<0.05)。试验组治疗后1周至1年的PLI和GI指数均明显低于治疗前,差异有统计学意义(P<0.05);而对照组治疗后1周和3个月的PLI和GI指数虽与治疗前比较,差异有统计学意义(P<0.05),但治疗后6个月至1年指数逐渐增长至治疗前水平。结论在口腔医疗服务中增加口腔卫生宣教和指导的内容,把口腔健康教育贯穿于老年牙周患者治疗的全过程,有助于牙周治疗效果的维护。
