Comparison of Physicochemical Surface Conditioning Methods for Adhesion of bis-GMA Resin Cement to Particulate Filler Composite and Surface Characterization

Abstract

This study compared the effect of physicochemical surface conditioning methods on the adhesion of bis-GMA based resin cement to particulate filler composite (PFC) Microtensile bond strength test (µTBS) was performed in a universal testing machine (1mm/min). After debonding, failure modes were classified using stereomicroscopy. Surface characterization was performed on a set of separate specimen surfaces using Scanning Electron Microscopy (SEM), X-Ray Dispersive Spectroscopy (XDS), X-Ray Photoelectron Spectroscopy (XPS) and Fourier Transform Raman Spectroscopy (FT-RS).
