Adhesive joint; resin material ,tooth substrate and hybrid layer in between Hybridization : is the phenomenon of replacement of the hydroxyapatite and the water in the surface dentin by resin. 0000001873 00000 n “Mild” self-etching partially removes the smear layer, forming a thin hybrid layer (Fig. 0000001696 00000 n This layer is an interface between dentin and adhesive resin and the final quality of dental restoration depends greatly on its properties. Dental adhesive resin cement. The importance of communication and trust in the context of global virtual teams has been noted and reiterated in the information systems (IS) literature. In restorative dentistry, the smear layer is composed of denatured collagen, hydroxyapatite and other cutting debris (2). This resin, in combination with the collagen fibers, forms a hybrid layer. Maintain hemostasis. Hydrolysis and leaching of resin adhesives are considered the primary reason for resin degradation within the hybrid layer, contributing to the reduction of bond strength overtime [ 1 ].

Adhesive resin should create the so-called hybrid layer (consisting of a collagen network exposed by etching and embedded in adhesive resin). The current restorative procedures often depend on substantially the infiltration of synthetic polymers of the adhesive system into partially or totally demineralized collagen fibers that make up the dentin organic matrix.
