OSARIO RUIZ, E. Control of the collagen network collapse: collagen remoral. Av Odontoestomatol [online]. 2004, vol.20, n.3, pp.123-130. ISSN 2340-3152.

Resin penetration into and its reaction with the components of conditioned, mineralised dental tissues is known to be the fundamental micromechanical mechanism by which restorative materials can be successfully bonded to teeth. Monomers penetrated into conditioned dentin and concentrated in a superficial region of resin-reinforced dentin contributing significantly to the bond. The reinforcement, known as hybridization, involved impregnation, co-mingling and envelopment of collagen bundles and encapsulation of hydroxyapatite crystallites. A doubt raised concerning the quantitative contribution which the collagen network made to interfacial bond strength. lncreasing the thickness of the collagen network did not influence the assembly strength, and removal of the collagen with 5% sodium hypochlorite provided similar values to those recorded when the network was present.

Keywords : Collagen removal; dentin; adhesion.
