Scotchbond MP and ART Bond were used without intentional enamel etching to bond a total of 43 resin composite restorations in Class V 'abrasion/ erosion' lesions. The cumulative loss rates after 6 months, 1 year, and 2 years, respectively, were Scotchbond MP: 9, 14, 27 per cent; and ART Bond: 0, 5, 5 per cent. These data were not compared because each material was used on different patients. The results support the higher bond strength to dentine in the laboratory of Scotchbond MP compared with its predecessor Scotchbond 2. There was a slight but clinically insignificant amount of enamel marginal staining for both products after 2 years, confirming the necessity to etch the enamel for effective marginal sealing.
在Ⅴ类“磨损/侵蚀”病变中,未对牙釉质进行故意酸蚀,使用Scotchbond MP和ART Bond粘结了总共43个树脂复合材料修复体。6个月、1年和2年后的累计脱落率分别为:Scotchbond MP:9%、14%、27%;ART Bond:0%、5%、5%。由于每种材料用于不同患者,因此未对这些数据进行比较。结果表明,与前身Scotchbond 2相比,Scotchbond MP在实验室中对牙本质的粘结强度更高。两年后,两种产品均出现了轻微但临床上无显著意义的牙釉质边缘染色,这证实了酸蚀牙釉质以实现有效边缘封闭的必要性。
