Nanodentistry is a branch that involves the maintenance and upgradation of oral health care yet more precise by employing nano materials, biotechnology, including tissue engineering & ultimatelty dental nanorobotics. Recent development of nanoparticles and nanotubes in operative dentistry, endodontics, peridontal management, has played a growing role in the enhancement of dental industry. Nanomaterials and nanoparticles are cornerstone of innovative  dental devices used for drug discovery and delivery,discovery of biomarkers and molecular diagnostics. Nanodentistry aims to manipulate and fine tune particles to create unique with novel properties and advances in dentistry.
