Abstract
Porous glass nanoparticles according to an embodiment have a specific surface area of 250 m2/g to 800 m2/g, and a pore volume of 0.1 cm3/g to 1 cm3/g. Since the porous glass nanoparticles have a high specific surface area and pore volume, the porous glass nanoparticles may have improved agilities to remineralize the demineralized dentin and occlude dentinal tubules. In addition, by including the porous glass nanoparticles, a dentin adhesive composition with improved adhesive strength to the dentin surface may be provided.
