The Basic Erosive Wear Examination (BEWE)

The BEWEintroduced by BartlettGanss and Lussi in 2008,⁸² is used to assess the level of erosion. For this examinationthe mouth is divided into six distinct areas for evaluation. Table 6 shows the criteria for sextant scores from 0 to 3which are summed to obtain a cumulative score that is the basis for determining interventions (Table 7). The BEWE is a simplequick index for screening a patient’s erosion status.

Table 6. BEWE Scores and Criteria.

Score	Criteria	Image
0	No ETW
1	Initial loss of surface texture
2a	Distinct defect; hard tissue loss involving <50% of the surface area
3a	Hard tissue loss involving ≥50% of the surface area

^aDentin often involved.
