This study evaluated the shear bond strengths of orthodontic brackets bonded to human premolars using five different combinations of flowable composites and one-step self-etching adhesives (n=12): (1) Adper Easy Bond+Filtek Supreme XT Flow; (2) Futurabond NR+Grandio Flow; (3) Clearfil S3 Bond+Clearfil Majesty Flow; (4) AdheSE One+Tetric EvoFlow; and (5) Transbond Plus Self Etching Primer+Transbond XT Light Cure Adhesive. After shear bond strength testing, adhesive remnant index (ARI) scores were given according to the amount of adhesive and resin remaining on the brackets. On shear bond strength, there were no statistically significant differences between Groups 2 and 4 and between Groups 3 and 5 (p>0.05). On ARI scores, the predominant ARI scores in Groups 1, 2, 3, and 5 were 4, 2, 5, and 4 respectively; in Group 4, they were 0 and 4. Results showed that some combinations of flowable composites and self-etching adhesives might not be suitable for orthodontic use due to their low shear bond strengths and high ARI scores -with the latter signaling the risk of damaging the enamel surface during debonding.
本研究评估了使用五种不同流动复合树脂和一步自酸蚀黏结剂组合（n=12）黏结到人前磨牙上的正畸托槽的剪切粘结强度：（1）Adper Easy Bond+Filtek Supreme XT Flow；（2）Futurabond NR+Grandio Flow；（3）Clearfil S3 Bond+Clearfil Majesty Flow；（4）AdheSE One+Tetric EvoFlow；和（5）Transbond Plus Self Etching Primer+Transbond XT Light Cure Adhesive。在进行剪切粘结强度测试后，根据粘结剂和树脂在托槽上的残留量，给予粘结残留指数（ARI）评分。在剪切粘结强度方面，组 2 和组 4 之间以及组 3 和组 5 之间没有统计学上的显著差异（p>0.05）。在 ARI 评分方面，组 1、2、3 和 5 的主要 ARI 评分为 4、2、5 和 4；组 4 的 ARI 评分为 0 和 4。结果表明，由于某些流动复合树脂和自酸蚀黏结剂组合的剪切粘结强度较低，ARI 评分较高，可能不适合正畸使用-后者表明在脱粘过程中损坏牙釉质表面的风险。
