目的:比较光固化复合树脂粘接剂与京津釉质粘接剂对正畸磨牙颊面管脱落率的影响。方法:选择60例直丝弓矫治病例,随即分为两组,两种粘接剂分别用于两组患者磨牙颊面管的粘接,比较颊面管的脱落情况。结果:两种粘接剂颊面管的脱落率差别经2检验有统计学意义。结论:使用光固化粘接剂粘接颊面管比京津釉质粘接剂脱落率低。
OBJECTIVE: To compare the effects of light-cured composite resin adhesive and Beijing-Tianjin enamel adhesive on the ablation rate of buccal tube of orthodontic molars. Methods: Sixty cases of straight wire were treated by straight wire and then divided into two groups. The two kinds of adhesives were used to bond the buccal surface of the two groups respectively, and the exudation of the buccal tube was compared. Results: The difference of the drop rate between the two adhesive buccal tubes was statistically significant by 2 test. Conclusions: The adhesive rate of buccal tube using light-curing adhesive is lower than that of Beijing-Tianjin enamel adhesive.
