Nanotechnology is the field of science and technology pertaining to the creation and use of materials or devices at nanometer scale1. A nanometer scale = one billionth of a meter. Nano is derived from vavos the Greek word for dwarf. The idea behind nano technology was originated with Nobel laureate Richard Feyman nearly 50 years ago. He described the development of tools for molecular engineering which in essence is building materials, molecule by molecule.Dentistry has seen many path-breaking events, which continued its progress towards achieving better materials, better techniques and better ways of treating humanity.Development of “Nanodentistry” will make possible the maintenance of near-perfect oral health through the use of Nanomaterials, biotechnology including tissue engineering and Nanorobot.
