摘　　要：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。Objective To inquire into the influence of three different treatment of the etched enamel on bracket bonding effect.Methods Compared the bracket bonding failure rate and ARI counts of 30 cases which treat the etched enamel surface with 5s air water gun rinsing,wet cotton ball wiping and alcohol cotton ball wiping respectively.Results The bracket bonding failure rate of the group which rinse the etched enamel 5s with air water gun is the lowest one.There are statistically significant difference between this group and two others.The ARI count of this group is higher than that of others.Conclusion The results suggest that rinse the etched enamel with the air water gun is a very important step to prevent the bracket bonding failure.
