Abstract:

Applications of nanotechnology for dental biomaterials are growing rapidly. Nanodentistry includes diagnosis and treatment of oral cancer, prevention of plaque accumulation, treatment of teeth hypersensitivity, replacing fractured enamel, restoration of carious teeth and root canal filling. Applying nanotechnology for restorative materials improved their physical and esthetic properties, adhesion and sealing that prolonged their durability. Coating implant with nanomaterial increased their wettability, antibacterial and osteoinductive function. Using Nanobiomaterials like anesthesia, needles, sutures and bone-replacing materials in surgeries facilitated non-invasive procedures without postoperative pain and complications. In spite of nanobiomaterials are non cytotoxic and do not cause health hazard, Nanotechnology did not improve their pyrogenicity. The biocompatibility of the biomaterial depends on their chemical components. Some studies showed that inhalation of Nanodental material dust penetrate alveoli and transported by blood to the liver and spleen. Nanobiomaterial used in surgeries are carried by the blood to the distant body organs and accumulated as non-degradable toxic components that are capable to cause harm to distant organs like lung, liver, spleen and kidney.
