Dental erosion due to intrinsic factors is caused by gastric acid reaching the oral cavity and the teeth as a result of wmiting or gastroesophageal reflux. Since clinical manifestation of dental erosion does not occur until gastric acid has acted 011 the dental hard tissues regularly over a period of several years. dental erosion caused by intrinsic factors has been observed only in those diseases which are associated with chronic vomiting or persistent gastroesophageal reflux over a long period. Examples of such conditions include disorders of the upper alimentary tract. specific metabolic and endocrine disorders. cases of medication side-effects and drug abuse. and certain psychosomatic disorders, e.g. stressinduced psychosomatic vomiting, anorexia and bulimia nervosa or rumination. Based on a review of the medical and dental literature, the main symptoms of all disorders which must be taken into account as possible intrinsic etiological factors of dental erosion are thoroughly discussed ivith respect to the clinical picture. prevalence and risk of erosion.
