[The influence of different treatment of the etched enamel on bracket bonding effect]

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 in 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.
