Epidemiological studies have shown that the prevalence of dental erosion inchildren varies between 2 and 57 %. Changes seen in dental erosion range from removal ofsurface characteristics to extensive loss of tooth tissue with pulp exposure.The etiology of dentalerosion is dependent on the presence of extrinsic or intrinsic acid in the oral cavity. Extrinsicsources of acids include frequent consumption of acidic foods and drinks,and acidic medications.Regurgitation of acidic content into the mouth, as occurs in gastroesophageal reflux, is the mostcommon source of intrinsic acid. A multitude of factors may modify the erosion process, such assaliva, oral hygiene practices, and presence or absence of fluoride. When dental erosion isdiagnosed, it is important to investigate and identify the acid source, and to determine if theprocess is ongoing. The aim of treatment is to eliminate the cause of acid exposure, and tominimize of effects of acid exposure where it is not possible to remove the acid source.Restoration of the dentition involves stainless steel crowns to restore lost vertical dimension,and composite resin for esthetics.
Key words: dental erosion, extrinsic acid, intrinsic acid
