Nano Science and Root Canal Therapy: A Literature Review

Nano science and nanotechnology have revolutionized all aspects in the endodontic field. The aim of the present study was to describe the application of nanotechnology in endodontics by reviewing the literature.The application of nanomaterials, with a smaller size, for surface modification has reduced the incidence of failure in the rotary nickel-titanium files. Nanoparticles with the ability of rapid dispersion into the hard-to-reach spaces in the complex root canal system have a better antimicrobial effect. The incorporation of nanoparticles in the obturating materials promotes the sealing properties and antimicrobial efficacy. Nanoscaffolds in the pulp regeneration approaches, bioceramics as retrofilling, and repair materials, and Nanorobots and nanoterminators as new technologies for local anesthesia with fewer side effects are some examples in this regard.
