Dental erosion
Dental erosion is the progressive, irreversible loss of dental hard tissue that is chemically etched away from the tooth surface by extrinsic and/or intrinsic acids. Dental erosion appears to be a growing problem in several countries, affecting 8–13% of adults (25), and the increasing levels are thought to be due to higher consumption of acidic beverages (i.e.sugary carbonated drinks and fruit juices). Worldwide, there is a need for more systematic population-based studies on the prevalence of dental erosion using a standard index of measurement.
