Abstract

Contemporary, third-generation dentinal bonding products have become highly specialized in producing high bond strengths to dentin. This investigation compared in vitro bond strengths of six dentinal bonding systems and their matched composite resins to human enamel and dentin. The effects of treatment by dentinal primers on enamel bond strengths as well as the effects of phosphoric acid on the strengths of dentinal bonds were measured. The use of dentinal primer on enamel improved the bond strengths of Prisma Universal Bond 3/Prisma APH and XR Bond/Herculite systems and had no effect on Denthesive/Charisma, Scotchbond 2/Silux, and Tenure/Perfection, while the enamel bond strengths of Gluma/Pekalux declined. Pretreatment of dentin with phosphoric acid improved the bond strengths of Denthesive/Charisma, Prisma Universal Bond 3/Prisma APH and XR Bond/Herculite, but had no effect on Gluma/Pekalux, Scotchbond 2/Silux and Tenure/Perfection.

摘要

当代的第三代牙本质粘结产品在实现与牙本质的高粘结强度方面已变得高度专业化。本研究比较了六种牙本质粘结系统及其配套复合树脂与人类牙釉质和牙本质的体外粘结强度。测量了牙本质底漆处理对牙釉质粘结强度的影响以及磷酸对牙本质粘结强度的影响。在牙釉质上使用牙本质底漆提高了Prisma Universal Bond 3/Prisma APH和XR Bond/Herculite系统的粘结强度，对Denthesive/Charisma、Scotchbond 2/Silux和Tenure/Perfection没有影响，而Gluma/Pekalux的牙釉质粘结强度下降。用磷酸预处理牙本质提高了Denthesive/Charisma、Prisma Universal Bond 3/Prisma APH和XR Bond/Herculite的粘结强度，但对Gluma/Pekalux、Scotchbond 2/Silux和Tenure/Perfection没有影响。
