Nanotechnology as defined by size is naturally broad, including fields of science as diverse as surface science, organicchemistry, molecularbiology, semiconductor physics, energy storage, engineering, microfabrication, and molecular engineering. The associated research and applications are equally diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to direct control of matter on the atomic scale. Nanotechnology has been greatly advanced since the past few decades. The role of nanotechnology in field of dentistry has evolved greatly. The use of various nanoparticles and materials in the field of periodontics has brought a new insight in terms of periodontal regeneration, control of biofilms, in treating dentinal hypersensitivity.
