摘　　要：目的:研究牙齿漂白对正畸托槽粘结强度的影响。方法:选取于中山大学孙逸仙纪念医院口腔正畸科就诊的患者60例,将患者分为未漂白组、漂白后即刻粘结组及漂白24h后粘结组,6个月后对三组的脱落率进行比较,结果:三组间差异具有统计学意义(P<0.05)。未漂白组的脱落率明显低于另外两组(P<0.05),即刻粘结组的脱落率明显高于其他两组(P<0.05)。结论:漂白对托槽的粘结有不利影响,其中以即刻粘结最为显著。Objective The purpose of this research was to investigate the influence of bleaching on orthodontic bracket adhesion. Methods A total of 60 patients （tooth） underwent fixed orthodontics in the orthodontic department of SUN YAT-SEN Memorial Hospital.All patients were divided into three groups according to the bleaching,after six months, we compared the loss rate. Results Statistically significant differences were observed between all the groups （P〈0.05）. The teeth of Non-bleaching group had lower loss rate than the other two groups,the different was significant （P〈0.05）.The risk of loss was significantly lower when the bracket was bonded immediately and return quickly after 24 hours （P〈0.05）. Conclusion The bleaching treatments did significantly reduce the bond strengths of orthodontic brackets,which had the worst effect when bonding immediately.
