摘要

Objectives: The purpose of this study was to develop an adhesive resin with incorporation of niobium pentoxide and evaluate its properties. Methods: Niobium pentoxide was characterised by X-ray diffraction, surface area, particle size, micro-Raman, scanning electron microscopy and the effectiveness of silanisation process by Fourier Transform Infrared (FTIR). An experimental adhesive resin was formulated with 0, 5, 10 and 20 wt% Nb2O 5. The formulated adhesive resins were evaluated based on microhardness, degree of conversion, radiopacity and interface (resin/dentine) characterisation by micro-Raman. Results: The particles used in this study presented a monoclinic crystalline phase with typical chemical groups and micrometre mean size. Microhardness and radiopacity increased with higher amounts of Nb2O5, and the particles were able to penetrate into the hybrid layers. Conclusions: Therefore, Nb2O5 may be an alternative for polymer-based biomaterials. Clinical significance: Niobium pentoxide could be used to produce adhesive resins with enhanced properties. ? 2012 Elsevier Ltd. All rights reserved.
