Influencia de la incorporación del copolímero del ácido polialquenoico en el comportamiento in vitro de diferentes sistemas adhesivos dentinarios

Abstract

To study the influence of polyalkenoic acid copolymer (also known as Vitrebond copolymer, VCP) on immediate (24h) and six-months (6m) bonding stability of VCPbased adhesives to dentin through microtensile bond strength (¿TBS), nanoleakage (NL) and ultra-morphological analysis of dentin¿resin interfaces (UM). Also a potential chemical interaction between synthetic hydroxyapatite (HAp) and VCP-based adhesives was evaluated through Fourier Transformed InfraRed (FTIR) and Nuclear Magnetic Resonance (NMR) spectroscopy.
