摘　　要：目的:比较两种不同正畸托槽粘接剂在去除托槽后对牙釉质表面的影响。方法:将40颗离体牙随机分为两组,实验组采用GC正畸用树脂强化型玻璃离子水门汀、对照组采用3M正畸光固化树脂型粘接剂进行金属托槽粘接。拆除托槽后分别对牙面粘接前、拆除托槽后和金刚砂车针+矽粒子序列抛光后的牙表面粗糙度值测量并进行分析对比;随机在两组中各选择4个样本,在托槽粘接前、拆除托槽后、金刚砂车针+矽粒子序列抛光后的釉质表面、剖面进行电镜观察。结果:在拆除托槽后牙面粘接剂的残留指数方面,实验组与对照组差异有统计学意义(P<0.05)。拆除托槽后牙面粗糙度值对比,两组差异有统计学意义(P<0.05);经过金刚砂车针+矽粒子序列抛光后对比,两组粗糙度值比较差异无统计学意义(P>0.05),但操作时间比较差异有统计学意义(P<0.05)。电镜显示:抛光后实验组牙面残留少,颗粒粗,牙釉质内树脂突少;对照组牙面残留多,颗粒细,牙釉质内树脂突多。结论:GC正畸用树脂强化型玻璃离子水门汀与3M正畸粘接树脂均易被金刚砂抛光车针+矽粒子序列抛光清除,但GC正畸用树脂强化型玻璃离子水门汀清除时间短,在牙釉质表面及釉质内残留少。Objective To compare the effects of two different orthodontic bracket cements on enamel surface roughness and morphology after bracket removal and polishing.Methods Forty teeth were randomly divided into two groups and bonded with metal brackets using either cement.Surface roughness was measured before bonding,after bracket removal,and after polishing.Enamel surfaces and cross-sections were viewed under electron microscopy at each step for four samples per group.Results The resin-reinforced glass ionomer cement left significantly less adhesive residue after bracket removal(P<0.05)and resulted in lower surface roughness compared to the resin-based adhesive(P<0.05).Following polishing,there was no significant difference in roughness between the two groups(P>0.05).Electron microscopy revealed fewer remnants,larger particles,and less resin protrusions in the enamel for the glass ionomer cement group after polishing.Conclusion Both cements can be effectively removed by diamond bur and particle polishing without damaging the enamel.However,resin-reinforced glass ionomer cement results in easier cleanup and less enamel roughness compared to light-cured resin-based adhesive for metal brackets.
