The bond strengths of resin systems to etched enamel. 1976

G M Short, and J H Hembree, and J P McKnight

This study was undertaken to compare the resin-enamel bond strengths of seven anterior restorative resins using the acid-etch technique. Six of the materials (Restodent, Enamelite, Smile, Nuva-System, Concise, and Adaptic) were composite resins. Only one, Sevriton, was an unfilled resin. Of the seven, only Sevriton and Smile were not designed for the acid-etch technique. Of the materials tested, Sevriton and Enamelite had the weakest bonds. There was no significant difference in the bond strength among Nuva-System, Smile, and Restodent; the bonds of all these were stronger than those of Sevriton and Enamelite. Concise showed a significantly greater bond strength than all the other materials in the study except Adaptic and the Nuva-System. The resin-enamel bond strength of Adaptic was of a greater magnitude than that of all other test materials.

UI	MeSH Term	Description	Entries
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.

D003188	Composite Resins	Synthetic resins, containing an inert filler, that are widely used in dentistry.	Composite Resin,Resin, Composite,Resins, Composite
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.
