[The erosive effect of various drinks, foods, stimulants, medications and mouthwashes on human tooth enamel].

Two forms of non-carious dental disorder - ero- sive tooth hard tissue loss and dental erosion - have been increasingly observed in recent years. Dental erosion is the chemical loss of dental hard substances caused by exposure to acids not de- rived from oral bacteria. Mechanical forces from, for example, the tongue, the cheeks or tooth- brushing, increase loss of partly demineralized tooth surfaces and the cumulative loss of dental hard tissue is defined as erosive tooth wear (ETW).

The erosive effect of various drinks, foods, stimulants, medications and mouthwashes on human tooth enamel.

Two forms of non-carious dental disorder - erosive tooth hard tissue loss and dental erosion - have been increasingly observed in recent years. Dental erosion is the chemical loss of dental hard substances caused by exposure to acids not derived from oral bacteria. Mechanical forces from, for example, the tongue, the cheeks or toothbrushing, increase loss of partly-demineralized tooth surfaces and the cumulative loss of dental hard tissue is defined as erosive tooth wear (ETW).

Effects of Calcium and Phosphate on Dissolution of Enamel, Dentin and Hydroxyapatite in Citric Acid.

The aim was to evaluate the effect of dissolved calcium and phosphate on dissolution rate of enamel, dentin and compressed hydroxyapatite (HA) in citric acid solution as a function of pH. At pH 2.5, dissolution rate of enamel increased significantly by 6% in 20 mmol/L added calcium but, otherwise, dissolution rates of neither enamel, dentin nor HA were significantly affected by 10 or 20 mmol/L calcium.

Consensus report of the European Federation of Conservative Dentistry: erosive tooth wear--diagnosis and management.

Objective: Due to an increased focus on erosive tooth wear (ETW), the European Federation of Conservative Dentistry (EFCD) considered ETW as a relevant topic for generating this consensus report.

Materials And Methods: This report is based on a compilation of the scientific literature, an expert conference, and the approval by the General Assembly of EFCD.

Results: ETW is a chemical-mechanical process resulting in a cumulative loss of hard dental tissue not caused by bacteria, and it is characterized by loss of the natural surface morphology and contour of the teeth.

Understanding the chemistry of dental erosion.

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 by solubility and also by other factors.
