Abstract
Nanotechnology has been widely introduced into many areas of dentistry, including restorative dentistry, where it has contributed greatly to the improvement of restorative materials and procedures. This review was conceived with the aim of exploring the various applications of nanotechnology in restorative dentistry. The review consists of two parts. The first part addressed applications for remineralization inhibition and remineralization. This current review is the second part aimed at focusing on the reinforcement of restorative materials and other therapeutic applications of nanomaterials. Among the nanoparticles that are used to reinforce restorative materials are carbon, zirconia, hydroxyapatite, titanium dioxide, alumina, and gold nanoparticles. Furthermore, other promising applications of nanotechnology are for hypersensitivity management, protective varnish, whitening effect, drug delivery, and nanorobotics, which includes performing major tooth repairs and conducting dentition renaturalization procedures. These applications highlight the potential of nanoparticles in restorative dentistry; however, there are still certain limitations that need to be handled.
