The purpose of this study was to investigate the bonding ability to enamel and dentin of the new single application bonding systems and compare these with a commercial compomer (Clicker/ F2000, 3M Dental Products), and two-step resin composite bonding systems (Fluoro Bond/ Lite-Fil II A, Shofu Inc. and Single Bond/ Z100, 3M Dental Products). Labial surfaces of extracted bovine teeth were ground on wet 600-grit SiC paper to expose a flattened area of enamel or dentin and then washed and dried with oil-free compressed air. These surfaces were treated according to each adhesive system's instructions and the restorative materials were condensed into a Teflon^【encircled R】 mold (2 mm height, 4 mm internal diameter) and then irradiated. The finished specimens were stored in 37℃ distilled water for 24 hrs from the start of light exposure to the material. Then these specimens were tested in a shear mode at a crosshead speed of 1.0 mm/min. The mean and standard deviation were subjected to an ANOVA followed by the Duncan test (p<0.05). The bond strengths of the single application bonding systems were 12.3〜14.5 MPa for enamel, and 13.7〜13.8 MPa for dentin. These values were comparable to those of the compomer, but lower than those of the two-step resin composite bonding systems. Clinical study using this newly developed single application system has been conducted.

本研究的目的是研究新的单一应用粘接系统对牙釉质和牙本质的粘接能力，并将其与商用复合体(Clicker/F2000，3M牙科产品)和两步树脂复合粘接系统(Fluoro Bond/Lite-Fil II A，Shofu Inc.和Single Bond/Z100，3M Dental Products)进行比较。拔除的牛牙的唇面在湿的600粒碳化硅纸上研磨，暴露出一块扁平的牙釉质或牙本质，然后用无油压缩空气清洗和干燥。这些表面按照每个粘接系统的说明进行处理，修复材料被凝结到聚四氟乙烯[环状R]模具(高度2 mm，内径4 mm)中，然后进行照射。从材料开始光照开始，将成品样品在37℃蒸馏水中储存24小时。然后以1.0 mm/min的十字头速度在剪切模式下对这些试件进行测试。对平均值和标准差进行方差分析，然后进行邓肯检验(p&lt；0.05)。两种粘接系统的粘结强度，牙釉质为12.3~14.5 Mpa，牙本质为13.7~13.8 Mpa。这些值与复合体相当，但低于两步树脂复合粘结系统的值。使用这一新开发的单一应用系统已经进行了临床研究。
