目的探讨三种临床常见的不同的酸蚀后牙面处理方法对托槽粘接效果的影响。方法对３０例气水枪冲洗，湿棉球擦拭及酒精棉球擦拭等三种不同酸蚀后牙面处理方法的临床托槽脱落率及粘接剂残留指数ＡＲＩ进行回顾性统计比较。结果气水枪冲洗酸蚀牙面组托槽脱落率最低，ＡＲＩ计分最高；湿棉球擦拭酸蚀牙面组及以酒精棉球擦拭酸蚀牙面组托槽脱落率较高，ＡＲＩ计分较低，后二者与前者相比，托槽脱落率存在着显著差异。结论该结果提示，以气水枪冲洗酸蚀牙面是防止托槽脱落的一个重要方法
Objective To investigate the effects of three different methods of dental treatment of acid etching on the adhesion of brackets. Methods Retrograde statistical comparison was made between the clinical brackets detachment rate and adhesive residue index (ARI) of 30 cases treated with gas-water gun washing, wet cotton ball wiping and alcohol cotton ball wiping. Results The gas-water gun rinse eroded tooth surface group brackets lowest shedding rate, ARI score the highest; Wet cotton ball wipe erosion tooth surface group and alcohol cotton ball wipe acid tooth surface group brackets off rate is high, ARI score Lower, the latter two compared with the former, there is a significant difference between bracket shedding rate. Conclusions The results suggest that flushing the etched tooth surface with gas-water gun is an important method to prevent the bracket from falling off
