... Abstract Dental erosion is the partial demineralisation of the tooth surface caused by repeated exposure to acids. The loss of surface tissue, which results from simultaneous and/or subsequent exposure to mechanical forces is known as erosive tooth wear (ETW). Excessive consumption of acidic...

... Abstract Tooth wear is the result of three processes: abrasion (wear produced by interaction between teeth and other materials), attrition (wear through tooth-tooth contact) and erosion (dissolution of hard tissue by acidic substances). A further process (abfraction) might potentiate wear...

... Abstract There is evidence that the presence of erosion is growing steadily. Due to different scoring systems, samples and examiners, it is difficult to compare the different studies. Preschool children from 2 to 5 years showed erosion on deciduous teeth in 1 to 79% of the subjects...

... Abstract Various assessment techniques have been applied to evaluate the loss of dental hard tissue and the surface-softened zone in enamel induced by erosive challenges. In this chapter, the most frequently adopted techniques for analyzing the erosively altered dental hard tissues are reviewed...

... Abstract When considering the erosive potential of a food or drink, a number of factors must be taken into account. pH is arguably the single most important parameter in determining the rate of erosive tissue dissolution. There is no clear-cut critical pH for erosion as there is for caries...

... of hydroxyapatite and the precipitation of calcium fluoride on the tooth surface. This layer has some protective effect against an erosive attack. However, when the pH is too low or when no fluoride is present these protecting effects are replaced by direct softening of the tooth surface. Oral dryness can occur...

... Abstract Dental erosion is caused by repeated short episodes of exposure to acids. Dental minerals are calcium-deficient, carbonated hydroxyapatites containing impurity ions such as Na + , Mg 2+ and Cl - . The rate of dissolution, which is crucial to the progression of erosion, is influenced...

... Abstract Gastric juice entering the mouth causes dental erosion. Common causes for the migration of gastric juice through the lower and upper oesophageal sphincters are reflux disease, laryngopharyngeal reflux, eating disorders, chronic alcoholism and pregnancy. Gastroesophageal reflux...

... Abstract Saliva is the most relevant biological factor for the prevention of dental erosion. It starts acting even before the acid attack, with an increase of the salivary flow rate as a response to the acidic stimuli. This creates a more favorable scenario, improving the buffering system...

... from the dentinal surface. With high probability, calcium- and phosphate-binding peptides and proteins adsorbed in the basal pellicle layer are of main relevance for the erosion-reducing effects of the natural salivary pellicle. Improvement of the pellicle's protective properties by dietary components...

... Abstract The role of fluoride in erosion therapy has long been questioned. However, recent research has yielded positive results. In this chapter, an overview of the literature is provided regarding the application of fluorides in the prevention and treatment of erosion and erosive wear...

... Abstract In recent years, different agents have been discussed as potential alternatives to fluoride in the prevention of dental erosion. These agents are intended to form acid-resistant layers on the surface, to induce repair of eroded lesions by mineral precipitation or to prevent...

... Abstract Dental erosion develops from the chronic exposure to non-bacterial acids resulting in bulk mineral loss with a partly demineralised surface of reduced micro-hardness. Clinical features are loss of surface structures with shallow lesions on smooth surfaces and cupping and flattening...

... Abstract Erosive tissue loss is part of the physiological wear of teeth. Clinical features are an initialloss of tooth shine or luster, followed by flattening of convex structures, and, with continuingacid exposure, concavities form on smooth surfaces, or grooving and cupping occuron incisal...

... Abstract There is some evidence that the presence of erosion is growing steadily. Because of differentscoring systems, samples and examiners, it is difficult to compare and judge the outcomeof the studies. Preschool children aged between 2 and 5 years showed erosion ondeciduous teeth in 6-50...

... Abstract Gastric juice entering the mouth causes dental erosion. Common causes for the migrationof gastric juice through the lower and upper oesophageal sphincters are reflux disease,eating disorders, chronic alcoholism and pregnancy. Gastro-oesophageal reflux is a commoncondition affecting up...

... Abstract Erosive tooth wear in children is a common condition. The overlapping of erosion withmechanical forces like attrition or abrasion is probably in deciduous teeth more pronouncedthan in permanent teeth. Early erosive damage to the permanent teeth may compromise thedentition...
