Dental Erosion
Meta Description: Dental erosion is a multifactorial condition characterized by smooth silky-glazed appearance of tooth surface, intact enamel along the gingival margin, grooving on occlusal surfaces, absence of perikymata and may lead to dentin hypersensitivity. Dental erosion is a multifactorial condition characterized by smooth silky-glazed appearance of tooth surface, intact enamel along the gingival margin, grooving on occlusal surfaces, absence of perikymata and may lead to dentin hypersensitivity. The erosive mechanism involves protons of the acidic agent attacking the components of hydroxyapatite such as carbonate, phosphate and hydroxyl ions, which results in hydroxyapatite crystal dissolution with a subsequent release of calcium ions. Chemical, biological and behavioral factors are involved in this process. Nowadays, changes in the nutritional habits and early dietary exposure to acid foods and acid drinks increased the prevalence of dental erosion, especially in younger age groups. The consumption of soft drinks, sport drinks and acid juices can decrease the pH of oral environment below the critical pH of 5.5 and subsequently lead to enamel and dentin demineralization.
