Betancourt DE(1), Baldion PA(1), Castellanos JE(2). Regardless of the strategy used, dentin bonding relies on the formation of the “hybrid layer” (HL), a structure composed of demineralized collagen fibrils reinforced by the resin matrix , . The layer of dentine which has been conditioned to remove the loosely adherent smear layer and into which adhesive resin has flowed to form a collagen/resin phase.Further Reading:Nakabayashi N., Nakamura M., Yasunda N. Hybrid layer as a dentin-bonding mechanism. As seen below in the elegant TEM from Dr. Bart Van Meerbeek, the hybrid layer is a resin-reinforced layer that “connects” the underlying intertubular dentin to the adhesive resin (Fig. 1994; 73:1212–20. This resin‐impregnation creates a transitional “hybrid” layer, that is neither resin nor tooth, but a hybrid of the two.

The hybrid layer formation was observed using scanning electron microscope and the extent of dye penetration was measured using a stereomicroscope. Test. hybrid layers.8,9 The use of weaker acids may influence the ability of these systems to provide consistently good interfa-cial seal, since the thickness of smear layer generated at the dentin surface is influenced by variables such as the type of bur, the speed, and the amount of water irrigation used during cavity preparation. A number of mechanisms (both mechanical and chemical) have been proposed as the cause of dentin adhesion. Group II: Uniform thin hybrid layer, with short multiple resin tags and lateral branchings.

J Dent Res 1956;35:846-851. These second-generation dentin bonding systems typically had in vitro bond strengths of only 1 to 5 MPa, which was considerably below the 10 MPa value estimated as the threshold value for acceptable in vivo retention.

Submitting a report will send us an email through our customer support system. Nor JE, Feigal RJ, Dennison JB. To substantiate this hypothetical insignificance of the HL, sodium hypochlorite (NaOCl) has been used to remove collagen from etched dentin prior to bonding. Composite resin is a restorative material widely used in dentistry for filling dental cavities and cementing indirect restorations and aesthetic restorations [1, 2]. When the hybrid layer becomes thicker and more uniform, the bond strength is better. The resin-dentin bond depends on the infiltration of the adhesive system into the collagen matrix of the dentin, which is exposed through acid conditioning.
