Dental 'erosion' revisited

Article Abstract:

Dentists must reevaluate their use of the term, erosion to describe processes that result in the loss of tooth substance. The scientific community defines pure erosion as the process of wearing away matter by fluid flow. The chemically-induced loss of tooth substance that dentists call erosion is more accurately classified as corrosion. Stress corrosion, an engineering term, describes mechanical stress combined with corrosion. This process takes place in the oral environment. Chewing, biting, swallowing, and grinding the teeth produce stress inside the mouth that is concentrated at the junction between the teeth and the gums. Forces cause the teeth to bend and may ultimately create microfractures called abfractions. The loss of tooth matter may result from a combination of processes including erosion and corrosion, abrasion and corrosion, abrasion and abfraction, or biocorrosion (cavities) and abfraction.

Attrition, abrasion, corrosion and abfraction revisited: a new perspective on tooth surface lesions

Article Abstract:

A schema of the pathodynamic mechanisms in the formation of tooth surface lesions like three basic physical and chemical mechanisms, their interactions and their dental manifestations are presented. The practitioner would be assisted in determining the etiology of various tooth surface lesions by using the precise definitions and would also be enabled to make accurate differential diagnosis.
