Micromorphology, microstructure and topography characterization of resin materials (original) (raw)

The morphologies, microstructures, of the adhesive restorative materials were systematically investigated. The objective of the present study was to make a comparative analysis of the physical properties by scaning electron microscopy and atomic force microscopy analysis of four different resins composite materials. For atomic force microscopy the materials were put between two matrix strips of celluloid and two glasses plates to obtain a flat surface. For scaning electron microscopy analysis the materials were put into standard dental human cavities performed with diamond burs The specimens were sectioned longitudinaly, flattened, polished, thermo cycled from 5 0 -50 0 C for 500 cycles, prepared for scaning electron microscopy observation (JEOLJSM 6390ª) and statistically analyzed using One-sample Test (p≤0.05). The surface roughness and topography were characterized by atomic force microscopy (Park SYSTEMS XE-100). There were differences in surface roughness microstructures and mo...
