Clinical Studies of Dental Erosion and Erosive Wear [PDF]

open access: yesCaries Research, 2011
We define <i>erosion </i>as apartial demineralisation of enamel or dentine by intrinsic or extrinsic acidsand <i>erosive tooth wear</i> as the accelerated loss of dental hard tissue through the combined effect of erosion and mechanical wear (abrasion and attrition) on the tooth surface.

Dental Erosion [PDF]

open access: yesPolish Journal of Public Health, 2014
Dental erosion is described as an irreversible loss of dental hard tissue resulting from exposure to non-bacterial acids or chelating substances. It may be caused by exogenous or endogenous factors. In the former case, food, drink, as well as the environment might be sources of acids; in the latter, acids flowing into the oral cavity from the stomach ...
