椅旁健康教育对慢性牙周炎患者维护期口腔卫生状况的影响

目的探讨椅旁健康教育对慢性牙周炎患者维护期口腔卫生状况的影响。方法 120例慢性牙周炎患者随机分为实验组和对照组,均给予洁治、龈下刮治和根面平整,实验组同时给予全面的口腔健康教育。于基线、基线后1、3、6个月检查Quigley-Hein菌斑指数。采用两组完全随机化设计资料均数的t检验分析所得数据。结果基线、基线后1个月时,两组间菌斑指数差异无统计学意义（t0=1.543,P0=0.1227;t1=1.925,P1=0.063）;基线后3、6个月时,实验组菌斑指数显著低于对照组（t3=19.153,P3=0.001;t6=25.265,P6=0.001）。结论实施全面的口腔健康教育可以显著改善牙周炎患者的口腔卫生状况。

The effect of oral health education on periodontal status during periodontal maintenance

Objective To investigate the effect of oral health education on oral health status during periodontal maintenance. Methods One hundred and twenty subjects were divided into 2groups： oral hygiene education group（experimental group） and ccontrol group. All the 2 groups received scaling and root planning, and the experimental group received comprehensive oral health education. Quigley-Hein plaque Indexes were examined at baseline, 1 month, 3 months, 6 months. The datas were statistically analysed by t test. Results There were no significant difference of Quigley-Hein plaque indexes between the experimental group and the control at baseline and 1 month（t0=1.543,P0=0.127;t1=1.925,P1=0.063）. At 3 months and 6 months, experimental groups had significantly lower Quigley-Hein plaque indexes than the control（t3=19.153,P3=0.001;t6=25.265,P6=0.001）. Conclusion Implementing comprehensive oral health education can improve oral health status during periodontal maintenance.
