【摘要】 [目的]比较光固化复合树脂粘接剂与京津釉质粘接剂应用于氟斑牙上对托槽脱落率的影响。[方法]选择24例氟斑牙正畸固定矫治病例,通过随机排列法将两种粘接剂分别与用于患者左右两侧上下颌的托槽粘接,比较其在4周、8周、12周时的托槽脱落情况。[结果]两种粘接剂的托槽脱落率经t检验差异有统计学意义(P﹤0.05)。[结论]光固化复合树脂粘接剂的托槽脱落率明显低于京津釉质粘接剂,建议在临床上对于氟斑牙患者有条件还是选用光固化复合树脂粘接剂,以减少托槽脱落。更多还原

【Abstract】 [Objective] To compare the influence on the failure rate of the bracket bonding to the dental fluorosis between the groups which applied the light-cured resin composite bond and the Jingjin enamel adhesive. [Methods] 24 patients who had the dental fluorosis and received the fixed orthodontic treatment were chosen. Two kinds of the adhesives were used to bond the brackets randomly. Compared the failure rates at the 4th week, 8th week and 12th week. [Results] The bracket bonding failure rates by using two kinds of the adhesives were statistically significant after t test (P﹤0.05). [Conclusion] The group which using the light-cured resin composite bind has significantly lower failure rate. It suggest we should use the lightcured resin composite bond to reduce the bracket bonding failure for the patients with the dental fluorosis.更多还原
