What is the BEWE?
Tooth surface loss can be caused by erosion, attrition, abrasion or abfraction.
The Basic Erosive Wear Examination (BEWE) is a simple, reproducible and validated screening tool aimed at recording and monitoring erosive tooth surface loss. Bartlett et al. (2008) introduced the BEWE to help with recording this information in a similar fashion to the BPE.
The BEWE quantifies the severity of erosive tooth surface loss across the dentition. This will also provide a summary score that can be used to categorise patients in to various risk levels and, therefore, guidance on management.
How to carry out the BEWE
Like the BPE, the mouth is divided in to sextants.
All tooth surfaces are then examined in each sextant and the most severely affected surface is identified.
Only the worst lesion in each sextant is scored.
