Bond strength of self-Adhesive Resin cements to different treated indirect composites
Clinical Oral Investigations, 2013Co-Authors: M. Victoria Fuentes, Laura Ceballos, Santiago González-lópezAbstract:Objectives The objective of this study was to determine microtensile bond strength (μTBS) to dentin of three self-Adhesive and a total-etch Resin cements used for luting different treated indirect composites. Materials and methods Composite overlays (Filtek Z250) were prepared. Their intaglio surfaces were ground with 600-grit SiC papers and randomly assigned to three different surface treatments: no treatment, silane application (RelyX Ceramic Primer), and silane agent followed by a bonding agent (Adper Scotchbond 1 XT). The composite overlays were luted to flat dentin surfaces of extracted human third molars using the following self-Adhesive Resin cements: RelyX Unicem, Maxcem Elite and G-Cem, and a total-etch Resin cement, RelyX ARC. The bonded assemblies were stored in water (24 h, 37 °C) and subsequently prepared for μTBS testing. Beams of approximately 1 mm^2 were tested in tension at 1 mm/min in a universal tester (Instron 3345). Data were analyzed by two-way ANOVA and Student–Newman–Keuls tests ( α = 0.05). Results A significant influence of the Resin cement used was detected. Composite surface treatment and the interaction between the Resin cement applied and surface treatment did not affect μTBS. Conclusions Surface treatment of indirect Resin composite did not improve the μTBS results of dentin/composite overlay complex. Self-Adhesive Resin cements tested obtained lower μTBS than the total-etch Resin cement RelyX ARC. Specimens luted with Maxcem Elite exhibited the highest percentage of pretesting failures. Clinical relevance Surface treatment of indirect Resin composite with silane or silane followed by a bonding agent did not affect bond strength to dentin.

recent advances in the theory and mechanism of Adhesive Resin bonding to dentin a critical review
Journal of Biomedical Materials Research Part B, 2009Co-Authors: T. K. Vaidyanathan, Jayalakshmi VaidyanathanAbstract:Dentin bonding issues involving Adhesive Resins have attracted considerable research interest in recent years. An important advance due to the ongoing research is the concept of hybridization of the tissue with primer/Adhesive systems. Hybridization involves permeation of primer monomer into the tissue substrate. Although the mechanism of Adhesive permeation and interaction with tissue may be complex, significant advances have been made. In systems where etching precedes priming and bonding steps, the Hoy's solubility parameter compatibility of the primer formulation with that of demineralized dentin matrix may determine Adhesive permeability. Monomer permeation brings the primer atoms in closer contact with the substrate atoms, leading to Adhesive interactions through van der Waals, hydrogen bonding, and electrostatic interactions. In self-etch primer systems, stronger electrostatic interaction between primer monomers and hydroxyapatite has been used to explain the adhesion process. These interactions have been computer-modeled and analyzed. Such interactions and subsequent polymerization of the monomer promote improved bond strength and efficient margin sealing. Incomplete permeation of monomer into the full depth of demineralized region may, however, leave exposed collagen fibrils and cause nanoleakage of water into these regions through a 20–100 nm sized marginal gap, leading to subsequent hydrolytic degradation of these collagen fibrils and the hybrid layer. Microleakage is also a problem in some single step formulations. In this review, we analyze these current theoretical and mechanism-related issues of interest in Adhesive Resin bonding to dentin, and outline the continuing problems that need to be overcome in the future. © 2008 Wiley Periodicals, Inc.

Effect of indirect composite treatment microtensile bond strength of self-Adhesive Resin cements.
Journal of Clinical and Experimental Dentistry, 2016Co-Authors: Mv Fuentes, Nuria Escribano, Bruno Baracco, Martin Romero, Laura CeballosAbstract:Background: No specific indications about the pre-treatment of indirect composite restorations is provided by the manufacturers of most self-Adhesive Resin cements. The potential effect of silane treatment to the bond strength of the complete tooth/indirect restoration complex is not available.The aim of this study was to determine the contribution of different surface treatments on microtensile bond strength of composite overlays to dentin using several self-Adhesive Resin cements and a total-etch one. Material and Methods: Composite overlays were fabricated and bonding surfaces were airborne-particle abraded and randomly assigned to two different surface treatments: no treatment or silane application (RelyX Ceramic Primer) followed by an Adhesive (Adper Scotchbond 1 XT). Composite overlays were luted to flat dentin surfaces using the following self-Adhesive Resin cements: RelyX Unicem, G-Cem, Speedcem, Maxcem Elite or Smartcem2, and the total-etch Resin cement RelyX ARC. After 24 h, bonded specimens were cut into sticks 1 mm thick and stressed in tension until failure. Two-way ANOVA and SNK tests were applied at α=0.05. Results: Bond strength values were significantly influenced by the Resin cement used ( p 0.05). All self-Adhesive Resin cements showed lower bond strength values than the total-etch RelyX ARC. Among self-Adhesive Resin cements, RelyX Unicem and G-Cem attained statistically higher bond strength values. Smartcem2 and Maxcem Elite exhibited 80-90% of pre-test failures. Conclusions: The silane and Adhesive application after indirect Resin composite sandblasting did not improve the bond strength of dentin-composite overlay complex. Selection of the Resin cement seems to be a more relevant factor when bonding indirect composites to dentin than its surface treatment.
