The BEWE, introduced by Bartlett, Ganss and Lussi in 2008,68 is used to assess the level of erosion. For this examination, the mouth is divided into six distinct areas for evaluation. Table 6 shows the criteria for sextant scores from 0 to 3, which are summed to obtain a cumulative score that is the basis for determining interventions (Table 7). The BEWE is a simple, quick index for screening a patient’s erosion status.
|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|
|Cumulative Score||General guidelines for management|
|No ETW: 0 - 2||
|Low: 3 - 8||
|Medium: 9 -13||
