Learn how to diagnose, monitor, and treat different types of tooth wear including erosion, attrition, abrasion, and abfraction with this infographic based on Dr. Glenn Clark’s course on abnormal oral physiology and sensory disorders.
Nov 7, 2015 · Dental attrition and abfraction are caused by bruxing, but the damage occurs at different points of the teeth. Abrasion is caused by rubbing against foreign objects and erosion is induced by chemical components.
Nov 2, 2020 · Attrition tends to result in flat lesions with sharp margins, whereas occlusal erosion leads to rounding of cusps and incisal edges. Generally, attrition creates corresponding wear facets on opposing teeth. Look for other signs of attritive wear, such as frictional keratosis or fracture lines in teeth/ restorations.
Abrasion is the same wear as attrition, but the factors that create it are external, while attrition occurs after tooth-grinding. Both are characterized by loss of tooth relief. Defects in abrasion-affected teeth are due to repeated contact with hard objects.

Sep 24, 2019 · Tooth surface loss (TSL) or tooth wear (TW) is an irreversible loss of hard tooth structure caused by factors other than those responsible for dental caries. TSL is observed clinically as attrition, abrasion, abfraction, and erosion.
