研究了自酸蚀底漆胶粘剂体系的组成对耐酸碱区(ABRZ)形貌的影响。本研究使用了一步自酸蚀底漆系统(Clearfi Tri-S Bond、G-Bond和One-Up Bond F Plus)和两步自酸蚀底漆系统(Clearfi SE Bond、Clearfi Protect Bond、联黎Bond和Mac Bond II)。将每种粘结剂涂在准备好的牙本质盘表面上，并在两个牙本质盘之间放置树脂复合材料。所有树脂粘结试件均经受酸碱挑战。扫描电子显微镜(SEM)下的观察显示，即使使用非氟化物释放粘合剂，所有自酸蚀底漆粘结剂系统的混合层附近也会产生ABRZ。两步法自酸蚀粘结剂中氟化物的存在显著增加了ABRZ的厚度。结果表明，使用自酸蚀底漆粘结剂系统可以形成ABRZ，但一步和两步自酸蚀底漆粘结剂系统的ABRZ形态不同，并受氟离子释放活性的影响。
This study investigated the influence of the composition of self-etching primer adhesive systems on the morphology of acid-base resistant zones (ABRZs). One-step self-etching primer systems (Clearfil Tri-S Bond, G-Bond, and One-Up Bond F Plus) and two-step self-etching primer systems (Clearfil SE Bond, Clearfil Protect Bond, UniFil Bond, and Mac Bond II) were used in this study. Each adhesive was applied on prepared dentin disk surfaces, and a resin composite was placed between two dentin disks. All resin-bonded specimens were subjected to acid-base challenge. Observation under a scanning electron microscope (SEM) revealed the creation of an ABRZ adjacent to the hybrid layer for all the self-etch primer adhesive systems, even when non-fluoride releasing adhesives were used. The presence of fluoride in two-step self-etching adhesive significantly increased the thickness of ABRZ created. Results suggested that an ABRZ was created with the use of self-etching primer adhesive systems, but its morphology differed between one-and two-step self-etching primer adhesive systems and was influenced by fluoride release activity.
