Review Article Recent Advances in Preventing Dental Erosion

Abstract

Dental erosion is defined as an irreversible loss of dental hard tissue due to exposure to chelating agents or non-bacterial acids. The occurrence of this condition was noted and the incidence and prevalence of dental erosion has been increasingly documented.The Ant erosive agents such as Anacardic acid in which the key component is the cashewnut shell liquid is phenolic lipids. It is a mixture of molecules which are saturated and unsaturated. It is also considered to have an anti-microbial effect and has been studied for the treatment of cancer, oxidative damage, inflammation and obesity disorders. Other anti-erosive agent like Fluoride helps in tooth remineralization. Fluorapatite, rather than hydroxyapatite, forms during the process of remineralization when fluoride is found in oral fluids. In apatite crystal lattice formation, fluoride ions replace hydroxy ions. Fluorapatite, even under acidic conditions, is less soluble than hydroxyapatite, which helps to regenerate tooth enamel. Fluoride is therefore a stronger anti-erosive agent. Various Recent advances in anti-erosive agents are Calcium and phosphate, Casein phosphopeptide amorphous calcium phosphate (CPP-ACP), Protease inhibitors, Oils, Chitosan chitosan and Multivalent metal ions Various techniques to evaluate dental erosion are in vitro techniques and in vivo techniques. In vitro techniques are Scanning electron microscope, Surface Profilometry, Polarized Light Microscopyand Non-Contact Confocal Laser Scanning Microscopy (CLSM). And iv vivo techniques are Photographs Clinical review and indices. The most important point of treatment is identifying and removing the erosion factor, above all current materials and methods. Therefore, early identification of the lesions, evaluation and removal of the etiological variables are relevant topics.
