          Abstract

          La presente revisión de la literatura aborda los conocimientos al respecto del empleo de los cementos de Ionómero Vítreo Convencionales como bases cavitarias para restauraciones de resina compuesta, analizando los principios de estos materiales dentales y aspectos clínicos relevantes durante su empleo que podrían perjudicar o por el contrario, optimizar la relación entre el cemento de ionómero vítreo y los adhesivos que emplean acondicionamiento ácido previo. Finalmente encontramos que las Técnicas de Acondicionamiento ácido selectivo y simultaneo, y la de Co-curado favorecen notablemente la manipulación y desenvolvimiento clínico del operador que lleva a cabo restauraciones directas tipo sándwich cerrado modificado

          Translated abstract

          The purpose of this review was examine and discuss the knowledges with regard to use of the Conventional Glass Ionomer Cement as cavity bases to restorations of composite resin, examining these dental materials's beginnings and clinical aspects relevant during his job that they would be able to harm or on the contrary, to optimize the relation among the cement of glass ionomer and the adhesives that use etch conditioning previous. Finally we find than etching simultaneous and selective technique, and Co-curing technique subserve notably the manipulation and the operator's clinical development that fellow implies to direct restorations closed sandwich

          Interaction of water-soluble collagen with poly(acrylic acid)

          Interactions between poly(acrylic acid) labeled with pyrene (PAA-Py) and succinylated calfskin collagen (type I) (SCSC) were studied by fluorescence spectroscopy. PAA-Py exhibits a strong emission from pyrene monomer (intensity, I(M)) when it exists in an extended conformation. It exhibits another broad emission from pyrene excimer (intensity, I(E)) when it adopts a collapsed globule conformation. At pH 3, a value that is lower than the isoelectric point of SCSC, the ratio I(E)/I(M) value decreased cooperatively with increasing concentration of SCSC at constant PAA-Py concentration, under salt-free condition. On the other hand, this effect was not observed in the presence of 0.1 M NaCl. At pH 7, a value higher than the isoelectric point of SCSC, the ratio I(E)/I(M) was not affected by the presence of SCSC in the absence and presence of salt. From electrophoretic light scattering experiments, it was found that at pH 3 PAA-Py was negatively charged, while SCSC had a positive charge. Thus it is strongly suggested that the two polymers interact by electrostatic attraction at low pH where they are oppositely charged, and that PAA-Py adopts an extended conformation in the complex formed with SCSC. Similar interactions are believed to occur between dentinal collagen and the polycarboxylate component of glass-ionomer cements.
