Erosion: Definition, Aetiology & Management

Definition: Progressive loss of hard dental tissues by a chemical process without bacterial or mechanical action.

Aetiology : Regurgitation and dietary erosion are recognized aetiological factors. The acidic nature of many foodstuffs or drinks can cause erosion of the dental hard tissues. If a patient suffers from gastrointestinal problems then gastric reflux may result and will produce an acidic oral environment. The clinician should always be aware of erosion caused by anorexia nervosa and bulimia. Other features which influence the erosive effect are the buffering capacity of saliva and medical conditions such as alcoholism.

Management: The aetiological factors implicated in the disease process should be identified and addressed as soon as possible. This preventive approach will stop further deterioration and may obviate the need to restore the eroded tooth surface.

The restoration of a dentition ravaged by the joint erosive/attrition action is a more commonly encountered problem that demands high levels of restorative skill to resolve.
