SANCHEZ AGUILERA, F; OSORIO, R  e  TOLEDANO, M. Control of the collagen network collapse: self-etching bonding systems. Av Odontoestomatol [online]. 2004, vol.20, n.4, pp.175-183. ISSN 2340-3152.

When dentin is etching the former (depth of dentin demineralization) excess the latter (depth of dentin diffusion / impregnation), a zone of hydroxyapatite depleted collagen fibers is left exposed, i.e., not resin infiltrated and nonhybridized. To avoid this, one option are the self-etching dentin bonding systems, that decalcify the inorganic component and infiltrate the collagen fibers at the same time by the action of acidic primers. In this article, the selfetching systems are characterized, and, their interfacial bond strength and the depth of demineralization of acidic primers are analysed.

Palavras-chave : Self-etching bonding systems; depth of demineralisation; bond strength.
