In order to repair the etched human dental enamel, 45S5 bioactive glass with different particle size was used to remineralization enamel in vitro. 45S5 bioactive glass powder was sieved, and divided into the three groups. Freshly sound human second molar teeth from patients were extracted and specimens of dentine-enamel junction were prepared under water-cooled diamond saw, then the enamel surface was polished and finally rinsed. The enamel samples were soaked in simulated oral fluid (SOF) for 5 days. Particle size distribution, topological images and mechanical properties such as hardness and reduced modulus of enamel surface were evaluated by the laser particle size analyzer, atomic force microscope (AFM) and nanoindentation technology. The results indicated that the adhered particle size onto the enamel surface was concentrated on the 1-10 μm. With the decreasing particle size, adhesive capacity onto the enamel surface increased, but the mechanical properties decreased gradually after soaking in SOF for 5 days. In a short period time, Group 2 particles are suitable of repair the etched enamel, and further improve its mechanical properties. This study suggests that proper size 45S5 bioactive glass may be used to repair the acid etched teeth as a toothpaste additive.

As the only bioactive material that can bond with both hard tissues and soft tissues, bioactive glass has become much important in the field of tissue engineering. 13-93 bioactive glass scaffolds were fabricated via selective laser sintering (SLS). It was focused on the effects of laser sintering on microstructure and mechanical properties of the scaffolds. The experimental results showed that the sintered layer gradually became dense with the laser power increasing and then some defects occurred, such as macroscopic caves. The optimum compressive strength and fracture toughness were 21.43?0.87 MPa and 1.14?0.09 MPa.m1/2, respectively. In vitro bioactivity showed that there was the bone-like apatite layer on the surface of the scaffolds after soaking in simulated body fluid (SBF), which was further evaluated by Fourier transform infrared spectroscopy (FTIR). Moreover, cell culture study showed MG-63 cells adhered and spread well on the scaffolds, and proliferated with increasing time in cell culture. These indicated excellent bioactivity and biocompatibility of nano 13-93 glass scaffolds.
