Dental Erosion Index

The Dental Erosion Index is a systematic clinical assessment tool that quantifies the severity of tooth surface loss caused by non-carious erosive agents (acidic substances, mechanical abrasion, or biological factors). Multiple index systems exist (e.g., Lussi Index, Basic Erosive Wear Examination or BEWE), each scoring erosion based on the extent and depth of surface loss on coronal and cervical tooth surfaces. Erosion assessment is critical for identifying patients at risk for advanced tooth loss, determining preventive interventions, and guiding restorative management.
