Nanotechnology (Nanohydroxyapatite Crystals): Recent Advancement in Treatment of Dentinal Hypersensitivity

Abstract

Dentinal hypersensitivity is often a chief concern among patients. A wide range of commercially available products for the treatment of dentinal hypersensitivity contain potassium, strontium, oxalates, fluoride salts and recently calcium sodium phosphosilicate and proarginine. More recently, the toothpastes containing carbonated hydroxyapatite nanocrystals are being studied. These have high reactivity by which they bind to enamel and dentine apatite producing a biomimetic coating on enamel, contrasting plaque formation. They also prevent tooth from decay, rebuild and revitalize the teeth and seal dentinal tubules, annulling hypersensitivity. In near future new products of this kind will be a breakthrough in the treatment of dentinal hypersensitivity.
