Abstract

Purpose: Present study investigated microtensile bond strengths (μTBS) of four one-step self-etch dental adhesive systems, two two-step self-etch adhesive systems and one three-step etch-and-rinse adhesive system to pulp chamber dentin. Materials and Methods: The μTBS of seven current adhesives, including one three-step etch-and-rinse (Optibond FL, Kerr, USA), two two-step self-etch (Clearfil SE Bond, Kuraray, Japan; AdheSE, Ivoclar, Liechtenstein) and four one-step self-etch adhesives (Clearfil S3 Bond, Kuraray, Japan; Optibond all-in-one, Kerr, USA; iBond, Heraeus Kulzer, Germany; L-POP, 3M ESPE, Germany) were determined. Adhesives were applied to pulp chamber dentin according to their respective manufacturer′s instructions, then μTBS tests were performed. Results: μTBS varied from 29.99 ± 7.82 to 38.15 ± 10.38 MPa. Highest μTBS mean was obtained with Optibond FL and lowest iBond, Heraeus Kulzer, Germany. There were no significant differences among all adhesives. Conclusion: Bonding effectiveness of one-step self-etch adhesive systems to pulp chamber dentin was comparable to two-step self-etch and three-step etch-and-rinse adhesive systems.
牙本质自蚀刻胶粘剂的研究现状
目的:研究4种一步自蚀牙胶体系、2种两步自蚀牙胶体系和1种三步蚀刻冲洗牙胶体系与牙本质的微拉伸结合强度(μTBS)。材料与方法:7种现有胶粘剂的μTBS,包括一种三步蚀刻-冲洗(Optibond FL, Kerr,美国),两种两步自蚀刻(Clearfil SE Bond, Kuraray,日本);AdheSE, Ivoclar,列支敦士登)和四种一步自蚀刻粘合剂(Clearfil S3 Bond,库拉雷,日本;Optibond一体机,科尔,美国;德国贺利氏古哲公司iBond;L-POP, 3M ESPE,德国)测定。将胶粘剂按各自生产厂家的说明书涂在牙本质上,然后进行μTBS测试。结果:μTBS变化范围为29.99±7.82 ~ 38.15±10.38 MPa。Optibond FL的μTBS平均值最高,德国贺利氏(Heraeus Kulzer)的μTBS平均值最低。各粘接剂间无显著性差异。结论:一步自蚀胶粘剂系统与牙本质的粘接效果与两步自蚀和三步蚀刻-冲洗胶粘剂系统相当。
