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。
Objective To evaluate the role of oral health education and guidance in the periodontal treatment of the elderly. Methods From June 2008 to June 2009, 100 patients with mild and moderate periodontal disease in the First People’s Hospital of Zhaoqing City were randomly divided into experimental group and control group, with 50 cases each. During the periodontal treatment of patients in the experimental group oral hygiene education and guidance. The plaque index-QT modified method (PLI-QT) and gingival index (GI) of the two groups were detected at 1 week, 3 months, 6 months and 1 year after initial diagnosis and 1 year respectively. Results There was no significant difference in PLI and GI index between the experimental group and the control group (P> 0.05). The difference of PLI and GI index between the two groups was statistically significant (P <0.05). The PLI and GI index in the experimental group from 1 week to 1 year after treatment were significantly lower than those before treatment (P <0.05), while the PLI and GI index in the control group at 1 week and 3 months after treatment were similar to those in the treatment group Before the comparison, the difference was statistically significant (P <0.05), but after 6 months to 1 year index gradually increased to the pre-treatment level. Conclusions The content of oral health education and instruction is increased in oral medical services, and the oral health education runs through the whole process of elderly patients with periodontal treatment, which is helpful to maintain the effect of periodontal treatment.
