Abfraction, Abrasion, Attrition, Erosion and Resorption. Ref.: 65

Abfraction is a loss of tooth structure, usually due to continuous trauma to the teeth caused by excessive force due to a bad bite. As tension zones are generated, microfractures are produced that in the long term can lead to the loss of enamel, dentin and cementum.

Attrition is a wear of the dental surfaces due to contact between them. This process frequently occurs in bruxing or clenching patients.

Erosion is the destruction of the tooth surface caused by external elements, usually chemicals and/or acids, such as those contained in carbonated beverages. Excessive consumption of these can lead to loss of enamel.

Root resorptions are defects in a tooth that can affect the enamel, dentin, cementum and pulp, usually caused by trauma, orthodontic treatment, cysts, impacted teeth, systemic, idiopathic or genetic diseases.

Resorptions can be external or internal.
