Abstract
Nanotechnology is considered to be an upcoming technology. Nanotechnology in the field of dentistry helps in diagnosis, prevention and treatment. Nanotechnology incorporates the usage of nanoparticles less than 100 nm. The usage of nanoparticles in restorative materials has increased the quality and life of dental restorations resulting in better oral care and hygiene. The technology helps in modifying the existing restorative material in terms of physical, chemical and biological aspects to improve their quality. Nanotechnology uses nanoparticles which are synthesized naturally from plants and chemically. The usage of specific nanoparticles is based on the properties and cytotoxic actions. Conventional GIC (Glass Ionomer Cement) and composites have been modified and improved in numerous ways by the addition of different nanoparticles. The restorative materials with nanoparticles currently used are nanocomposites, nano glass ionomers, nano adhesives and endodontic sealers. Nanotechnology is paving the way for recent advances in nanomaterials innovations. The advances of nanoparticles are helping the future of dentistry and production of new developments of materials with high quality. The main drawback faced in using nanoparticles is the toxicity produced by the nanoparticles but the demand for nano based dental material preparation has increased so there is a need for new nanomaterials. The review article provides an overview of the advancement of nanotechnology in restorative dentistry.
