“…Optical sections in the z-axis with CLSM were performed in a depth of 100µm in order to include the whole apatite layer, which has been reported in previous work by the authors to possess a mean thickness of 50µm [6,9]. Statistical analysis of topography profiles on specimens' surface revealed high surface roughness values which were in the range of 30-70µm (Fig.…”

Surface topography plays an important role in determining the functional performance of engineering materials as well as cell-material interactions. In this work is investigated the surface topography of an apatite layer that was developed on Bioglass® (PerioGlas® Synthetic Bone Graft Particulate, US Biomaterials)-modified dental ceramics, used in fixed prosthetic restorations, after immersion in a Simulated Body Fluid (SBF). The visualization of the surface morphology and structure and the gradual formation of the apatitic layer were followed by CLSM, as well as by ESEM and EDS. Topography profiles on specimens’ surface revealed high surface roughness and a fluctuation of RMS values in relation to immersion time in SBF, due to the continuing process of apatite precipitation.

“…Bioactive glasses with a nominal composition of 60% SiO 2 , 36% CaO and 4% P 2 O 5 (wt %) have excellent potential for bone tissue engineering applications by presenting a high level of bioactivity and developing an HA layer. 7 Thus, in the study nanoparticles with this tri-component nominal composition were synthesized by the sol-gel route, however, adding fluorine for the development of a material with additional interest for the dental field. Brauer 8 reported the synthesis of bioactive glass containing fluorine by conventional fusion, a process that requires high temperature.…”

In the last decades, studies about the specific effects of bioactive glass on remineralization of dentin were the focus of attention, due to their excellent regenerative properties in mineralized tissues. The incorporation of Fluorine in bioactive glass nanoparticles may result in the formation of fluorapatite (FAP), which is chemically more stable than hydroxyapatite or carbonated hydroxyapatite, and therefore is of interest for dental applications. The aim of this study was to synthesize and characterize a new system of Fluorine-containing bioactive glass nanoparticles (BGNPF). A sol-gel route assisted by ultrasound was used for the synthesis of BGNPF. The particles obtained were characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), atomic force microscopy (AFM), X-ray diffraction (XRD), dynamic light scattering (DLS), nitrogen adsorption, and X-ray photoelectron spectroscopy (XPS). SEM micrographs showed that the particles are quite uniform spherical nanostructures, occurring agglomeration or partial sinterization of the particulate system after heat treatment. XRD and XPS analysis results suggest the formation of fluorapatite crystals embedded within the matrix of the bioactive glass nanoparticles.
