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.

D011897	Random Allocation	A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects.	Randomization,Allocation, Random
D001840	Dental Bonding	An adhesion procedure for orthodontic attachments, such as plastic DENTAL CROWNS. This process usually includes the application of an adhesive material (DENTAL CEMENTS) and letting it harden in-place by light or chemical curing.

D003743	Dental Enamel	A hard thin translucent layer of calcified substance which envelops and protects the dentin of the crown of the tooth. It is the hardest substance in the body and is almost entirely composed of calcium salts. Under the microscope, it is composed of thin rods (enamel prisms) held together by cementing substance, and surrounded by an enamel sheath.
