This study was to investigate the accumulation and the possibility of utilization of the fundamental knowledge for HEMA free total etch adhesive systems development were performed. All teeth were subjected to a bonding treatment strictly according to the manifacture's instruction, with total etch adhesives, Unifil Bond (UH, JISHI) and Clearfil Linerbond II (CL II, Kuraray), Clearfil Mega Bond (CMB, Kuraray), One up Bond F (OBF, Tokuyama), HEMA-free in total etching systems (trial production, GC). All specimens were randomly divided into 3 groups (CMB, OBF, HEMA-free) of 6 teeth each, and subjected to μTBS-testing after 24 hour's storage in water at 37℃. Consequently, each of UB, CL II, and CMB became clear that the very thin hybrid layer with a thickness of 0.5-1 micrometer is formed by the adhesion interface with dentine. In the adhesion examination, although a significant difference was not accepted in CMB and a trial production self etching system, the significant difference was accepted by OBF and the trial production. Then, it is thought including adhesion durability, such as giving thermalcycle stress, that it is necessary to add consideration synthetically Moreover, in this time, it was suggested by choosing a suitable functional monomer and suitable polymer that utilization of a HEMA free total etch adhesive system are possible

本研究旨在探讨HEMA自由全蚀刻胶粘剂系统开发的基础知识积累和利用的可能性。所有牙齿严格按照制造商的说明进行粘接处理，使用全蚀刻胶，Unifil Bond （UH， JISHI）和Clearfil Linerbond II (CL II, Kuraray), Clearfil Mega Bond (CMB, Kuraray), One up Bond F (OBF, Tokuyama)，全蚀刻系统中不含hema（试验生产，GC）。将标本随机分为3组（CMB组、OBF组、不含hema组），每组6颗牙，37℃水中保存24 h后进行μ tbs测试。因此，UB， CL II和CMB都清楚地表明，与牙本质的粘附界面形成了厚度为0.5-1微米的极薄杂化层。在附着力检测中，虽然CMB和试制自蚀刻系统不接受显著差异，但OBF和试制系统接受显著差异。然后，认为包括粘接耐久性，如给予热循环应力，有必要综合考虑。在此期间，建议通过选择合适的功能单体和合适的聚合物，利用无HEMA的全蚀刻粘接体系是可能的
