在两种不同的洞型设计中，评价了两种牙本质粘合剂Clearfil New Bond和Scotchbond 2的临床有效性。A组无釉质斜面或酸蚀，有对接洞; B组有釉质斜面、酸蚀和羽毛状边缘洞。监测2年的保持率和边缘适应。在Clearfil系统中，21%的A组置换在2年后失败，而几乎所有的B组置换（99%）均得以保留。此外，2年后，Scotchbond 2系统中的脱粘A组脱粘总面积扩大至13%，而B组无脱粘丢失。无论粘合系统如何，随时间的推移都有明显的边际恶化。尽管如此，与Scotchbond 2粘合剂和Silux Plus复合树脂修复相比，Clearfil New Bond粘合剂联合Clearfil Ray复合树脂修复的宫颈病变边缘适应性缺陷较少。扫描电镜观察显示，充填物丢失的洞内牙本质表面有复合树脂残留，表明粘接接头部分内聚失效。
The clinical effectiveness of two dentin adhesives, Clearfil New Bond and Scotchbond 2, was evaluated in two different cavity designs. Group A was without enamel bevel or acid etch and with a butt-joint cavity; and group B had enamel bevel, acid etch, and feather-edged cavities. The retentive rate and marginal adaptation were monitored for 2 years. In the Clearfil system, 21% of group A restorations failed after 2 years, whereas virtually all the group B restorations (99%) were retained. In addition, after 2 years, the total of debonded group A restorations in the Scotchbond 2 system expanded to 13%, whereas no restorations from group B were lost. There was clearly marginal deterioration in time irrespective of the bonding system. Nevertheless, the marginal adaptation of cervical lesions restored with Clearfil New Bond adhesive in combination with Clearfil Ray composite resin revealed fewer defects compared with the Scotchbond 2 adhesive with Silux Plus composite resin restorations. SEM evaluation disclosed composite resin remnants on the dentin surface in cavities with lost fillings, which indicates partial cohesive failure of the adhesive joint.
