研究了磷酸（PA）酸蚀对两步自酸蚀粘接剂（SEA）与牙釉质粘接强度和耐酸碱区（ABRZ）形成的影响。使用蚀刻和冲洗粘合剂（ESTO）系统Single Bond（SB）和两步SEA系统Clearfil SE Bond（SE）。将人牙随机分为4组：1）SB组; 2）SE组; 3）35% PA酸蚀SE底漆SE粘接剂（PA/SEp+a）组;（4）35% PA酸蚀SE粘接剂（PA/SEa）组。测量微剪切粘结强度，然后使用单因素方差分析和Tukey诚实显著性差异检验进行统计学分析。记录失效模式，并通过e检验进行分析。用扫描电镜观察釉质表面酸蚀形态。将结合界面暴露于去矿物质溶液（pH=4.5）4.5小时，然后在超声处理下暴露于5%次氯酸钠30分钟。氩离子刻蚀后，用扫描电镜观察了界面的超微结构。SE组与釉质的微剪切粘结强度显著低于对照组（p
This study examined the effect of phosphoric acid (PA) etching on the bond strength and acid-base resistant zone (ABRZ) formation of a two-step self-etching adhesive (SEA) system to enamel. An etch-and-rinse adhesive (EAR) system Single Bond (SB) and a two-step SEA system Clearfil SE Bond (SE) were used. Human teeth were randomly divided into four groups according to different adhesive treatments: 1) SB; 2) SE; 3) 35% PA etching SE primer SE adhesive (PA/SEp+a); (4) 35% PA etching SE adhesive (PA/SEa). Microshear bond strength to enamel was measured and then statistically analyzed using one-way analysis of variance and the Tukey honestly significant difference test. The failure mode was recorded and analyzed by e test. The etching pattern of the enamel surface was observed with scanning electron microscope (SEM). The bonded interface was exposed to a demineralizing solution (pH=4.5) for 4.5 hours and then 5% sodium hypochlorite with ultrasonication for 30 minutes. After argon-ion etching, the interfacial ultrastructure was observed using SEM. The microshear bond strength to enamel of the SE group was significantly lower (p
