参与型口腔健康教育对口腔卫生知信行的影响

目的评价参与型口腔健康教育对牙周健康状况及相关知识、行为改善的影响。方法将北京市两个城区中8个社区或单位的300名15～64岁的志愿参加者分为实验组（参与组）和对照组（常规教育组）。参加者在基线、6个月和12个月时，接受牙周健康状况的检查和问卷调查。基线检查后，对所有参加者进行龈上洁治术。随后对实验组在专题小组访谈的基础上，进行小组讨论形式的参与型口腔健康教育，在6个月当中，提供在家使用的保健牙刷、牙间隙刷、牙膏和菌斑染色片。同时，提供专为口腔健康教育设计的阅读材料。对照组发给同样内容的健康教育阅读材料。最后比较两组间在牙周健康状况、口腔卫生知识和行为方面的改善情况。结果12个月后实验组牙石指数的均值明显低于对照组（P〈0．05），并有显著性差异。在口腔卫生知识和行为方面，实验组也在刷牙方法、选择保健牙刷、更换牙刷频率和使用牙间隙刷上比对照组提高了8．7％～31．3％。结论参与型口腔健康教育方法能明显改善牙周健康状况，能提高参与者的口腔卫生知识和行为。
