基于剪切粘结强度(SBS)测试和表面自由能(SFE)测量，我们试图确定在不同酸蚀模式下通用粘结剂应用时间对牙本质粘结性能的影响。使用的五种通用粘合剂是Adhese Universal(AU)、Clearfi Universal Bond Quick(CQ)、G-Premio Bond(GP)、Scotchond Universal(SU)和Tokuyama Universal Bond(TU)。将牛牙本质标本分成4组，每组10个粘结剂。应用以下表面处理后测定SBS和SFE：1)涂胶后立即吹气的自酸蚀(SE)模式(IA处理)，2)延长涂胶时间的SE模式(PA处理)，3)IA处理的酸洗(ER)模式，4)PA处理的ER模式。对粘结试件进行SBS测试。用丙酮和水冲洗牙本质表面，测定粘接剂处理后牙本质表面的SFE。三因素方差分析显示，牙本质SBS值(P
We attempted to determine the effect of universal adhesive application time on dentin bond performance in different etching modes based on shear bond strength (SBS) tests and surface free energy (SFE) measurements. The five universal adhesives used were Adhese Universal (AU), Clearfil Universal Bond Quick (CQ), G-Premio Bond (GP), Scotchbond Universal (SU), and Tokuyama Universal Bond (TU). Bovine dentin specimens were divided into four groups of 10 for each adhesive. SBS and SFE were determined after applying the following surface treatments: 1) self-etch (SE) mode with immediate air blowing after adhesive application (IA treatment), 2) SE mode with prolonged application time (PA treatment), 3) etch-and-rinse (ER) mode with IA treatment, and 4) ER mode with PA treatment. Bonded specimens were subjected to SBS testing. The SFE of adhesive-treated dentin surfaces was measured after rinsing with acetone and water. Three-way analysis of variance revealed that dentin SBS values (p
