OBJECTIVE
To evaluate the effect of applying an adhesive, prior to different flowable composite resins, on the shear bond strength (SBS) of orthodontic brackets to acid-etched human enamel.
MATERIALS AND METHODS
One hundred metal brackets were bonded to 35% phosphoric acid-etched human premolars using four flowable composites (Admira Flow, Tetric Flow, Filtek Supreme, Transbond Supreme) and a conventional orthodontic composite resin (Transbond XT). For each experimental group, half of the specimens were bonded in combination with Transbond XT adhesive. After 24 hours of storage, an SBS test was performed. Adhesive remnant index scores were determined after the failure of brackets. Two-way analysis of variance and Student-Newman-Keuls multiple comparison tests were performed at P < .05.
RESULTS
When using an adhesive system, the five composites performed equally. The application of adhesive had a significant effect on SBS. Without adhesive, SBS decreased in all groups, except for Transbond Supreme LV. All the test groups exhibited similar bracket failure modes.
CONCLUSIONS
When using an adhesive system, flowable composite resins exhibited similar SBS. Transbond Supreme was the only resin performing similarly with or without adhesive system application.
目的
评估在不同流动复合树脂之前应用胶粘剂对酸蚀人釉质正畸托槽的剪切结合强度（SBS）的影响。
材料和方法
使用四种流动复合树脂（Admira Flow、Tetric Flow、Filtek Supreme、Transbond Supreme）和一种传统正畸复合树脂（Transbond XT），将 100 个金属托槽粘结到 35%磷酸酸蚀的人前磨牙上。对于每个实验组，一半的样本与 Transbond XT 胶粘剂结合使用。储存 24 小时后，进行 SBS 测试。在托槽失效后确定胶粘剂残留指数得分。在 P <.05 时进行双向方差分析和 Student-Newman-Keuls 多重比较检验。
结果
使用胶粘剂系统时，五种复合材料的性能相当。胶粘剂的应用对 SBS 有显著影响。不使用胶粘剂时，除 Transbond Supreme LV 外，所有组的 SBS 均降低。所有测试组均表现出相似的托槽失效模式。
结论
使用胶粘剂系统时，流动复合树脂表现出相似的 SBS。Transbond Supreme 是唯一一种无论是否应用胶粘剂系统，其性能都相似的树脂。
