摘　　要：目的 研究固定矫治器及患者的行为因素对菌斑附着的影响。方法 通过100例正畸儿童使用菌斑染色剂染色并给予全面的口腔卫生指导,分别对矫治前、矫治初期、矫治末期、保持期进行菌斑指数（PLI）测试及比较。结果 矫治末期及保持期与矫治前比较,PLI下降（p值分别为P<0.01,P<0.001）,有显著性意义。矫治初期PLI高于矫治前0.05,保持期的PLI低于矫治末期0.02,无统计学意义。结论 固定矫治器客观上会妨碍口腔卫生,但患者的认识和行为因素对口腔菌斑附着的影响更重要于固定矫治器。Objective To study the effects of fixed appliance and behavior factors of patients on buccal plaque. Methods Investigate the plaque index (PLI) of 100 cases of orthodontic children in pre-treatment, initial-treatment, post-treatment and maintainer by using plaque disclosing agent. Results The PLI in post-treatment and maintainer was lower than that of the pre-treatment (p < 0.01 and p < 0.001) . The PLI in initial-treatment was higher than that of pre-treatment; the PLI in maintainer was lower than that of post-treatment. Conclusion The fixed appliance objectively affected the oral health, but the awareness and behavorial factors of the patients produced a greater effect than that of the fixed appliance.
