Nanotechnology applied to dentistry will bring significant advances in the diagnosis, treatment and prevention of disease. It is a wide range of new technologies utilizing the unique physical properties of materials. Current work of nanotechnology is focused on the recent developments, particularly of nanoparticles and nanotubes in nanocomposites, operative dentistry , endodontics, periodontal management, nanoporous materials and nanomembranes will play a growing role in materials development for the dental industry. The major investments aimed towards developing the methods to grow tooth structures artificially by soft chemical approaches and find the mechanisms for remineralization of dental defects at various scales in vivo, certainly presents a promising trend.
