[摘要]目的：初步探讨口腔综合防治措施对患者菌斑指数的影响。方法：将固定矫治后牙釉质脱矿需接受护牙素治疗的20例青少年患者，随机原则分实验组和对照组各10例患者。实验组用Tooth Mousse护牙素全口局部涂抹并按事先制订的口腔综合防治计划，采用语言、示范、文字相结合的教育方式，对患者进行口腔卫生宣教。对照组仅用Tooth Mousse护牙素局部涂抹治疗，不做口腔卫生宣教。比较两组基线、基线后1周，基线后4周菌斑指数的变化。结果：实验组基线后1周、基线后4周菌斑指数较基线减少并好于对照组，组间比较有统计学差异，但实验组基线后4周菌斑指数较基线后1周有所反弹。结论：口腔综合防治措施有助于控制固定矫治后牙釉质脱矿患者的菌斑指数，有利于牙釉质的再矿化。

Abstract: Objective To preliminary explore the influences of comprehensive oral health care on plaque index of patients. Methods 20 Teenage patients who needed treating by GC Tooth Mousse were randomly divided into control group and experimental group.Experimental group were treating by Tooth Mousse and comprehensive oral health care including health training of language,demonstration,and material.Control group were treating only by Tooth Mousse.Compare the change of plaque index on baseline,1 week later,4 week later. Results Plaque index of experimental group decreased,it was significantly better than control group on 1 week and 4 week later.But the plaque index of experimental group on 4 week point were increased than 1 weeek point. Conclusion Comprehensive oral health care can control the plaque index of patients who has enamel demineralization around orthodontic brackets,it was in favour of enamel remineralization.

牙面出现白垩色斑点，甚至呈凹坑状，这是牙釉质的脱矿现象。据国外资料统计，正畸患者釉质脱矿的发病率为50%[1]。国内统计高达59.4%，牙齿釉质脱矿的发病率为12.5%[2]。但是，通过加强口腔卫生护理与患者的共同努力，这些并发症在很大程度上是可以减少或避免的。本研究对2010年2月～2011年3月在本院口腔科就诊，对固定矫治后牙釉质脱矿者给予护牙素治疗并加强对患者的卫生宣教，现场指导并在模型上演示等多种方式的口腔综合防治，使患者的菌斑指数得到了较好的控制，取得了较满意的效果，现报道如下。
1 材料和方法
1.1病例资料：选择2010年2月～2011年3月门诊中固定矫治后牙釉质脱矿需接受护牙素治疗的90例(男37例，女53例)，年龄13～18岁，平均15.3岁。纳入标准：①患牙为固定矫治后牙釉质脱矿的青少年；②为初次护牙素治疗；③对护牙素无过敏；④无牙周炎；⑤体检后健康无系统性疾病；⑥能坚持治疗者。排除标准：①患牙为再次护牙素治疗；②对护牙素过敏；③患牙合并有牙周炎；④患者有系统性疾病；⑤不能坚持治疗者。
