Nanotechnology involves the research, development, and manufacturing of materials and devices measured on the nanometer scale. Materials with constituents less than 100 nm in at least one dimension can be classified as nanomaterials. Nanotechnology has found its way into commercial applications of cosmetics, food packaging, and disinfectants for the past two decades.In the field of medicine, nanotechnology and nanomaterials are used for prevention, diagnosis, and treatment.Nanomedicine is involved in multiple facets such as drug delivery, surgery, restoration, and replacement of tissues. In dentistry, nanoscience has gained impressive traction in the recent past as it deals with nanostructures for diagnostics and treatment of dental diseases.The aim is to attain perfect oral health with the regeneration of oral tissues using nanomaterials, bioengineering, and nanorobotics.The concept of nanotechnology was first introduced by Richard Feynman in 1959 at a lecture at Caltech where he discussed information on a small scale and the unavoidable use of small robots and computers shortly.
