Physical–chemical and biological properties of novel resin-based composites for dental applications

Abstract Insufficient mechanical properties of hydroxyapatite-based composites prompted the search for new and effective solutions dental applications. To improve without losing remineralization potential, use hybrid fillers was proposed. The first them based on formation hydroxyapatite (HA) layer surface SYLOID®244 silica. second investigated created by simultaneous synthesis nanoparticles from precursors HA obtained were extensively characterized spectral methods including X-ray Diffractometry (XRD), Fourier-Transform Infrared Spectroscopy (FT-IR), fluorescence (XRF), as well Scanning Electron Microscopy (SEM)/Energy Dispersive (EDS). Tests using probiotic microorganisms an important part analysis, indicating that there no potential interaction materials with microflora. tests degree conversion, depth cure, opacity, sorption, solubility, flexural compressive strength, remineralizing also showed nano-sized silica/HA better than alone or commercial silica at same time remained desired level. Thus, proposed composite has a high application in creation implants materials. Graphical abstract
