RESUMEN
Con el grabado ácido se obtiene un frente de desmineralización con un grosor diferente y mayor que el frente de infiltración de la resina, dando lugar al colapso del colágeno. Para solventar el problema aparecieron los sistemas autograbadores que a medida que desmineralizan van infiltrando la dentina. Se caracterizan los autograbadores dentro de los sistemas adhesivos y se analizan las fuerzas de adhesión que producen y los factores de que depende la profundidad de desmineralización de sus imprimadores (AU)
ABSTRACT
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 (AU)
