BARTLETT, Prosthodontics, King's College London Dental Institute, London, England, UkObjectives: The Basic Erosive Wear Examination (BEWE) is a practical index for assessing tooth wear, using a four point ordinal scale (0-3). The highest score is recorded in each sextant and a total score (or BEWE sextant cumulative) is calculated per subject. This study aims to investigate if the BEWE sextant cumulative score compares to one comprising a cumulative score from each tooth surface. The aim is to assess the validity of the BEWE sextant score. Methods: 175 subjects were recruited from hospital and general practice in south-east England. Buccal, occlusal and lingual/palatal BEWE scores were collected for each tooth surface and percentages calculated per subject based on scores 1, 1 and above, 2 and above and 3. BEWE sextant cumulative scores and highest BEWE scores were also recorded per subject. Spearman correlation coefficients (p values) were used to assess the relationship between BEWE sextant cumulative, BEWE percentages and BEWE highest per subject. Results: Positive correlations were indicated with the BEWE sextant cumulative score and were strongest where specified* below;BEWE scoreTooth surfacesAll tooth surfacesBuccalOcclusalLingualBEWE (1)0.254 (<0.001)0.338 (<0.001)0.098 (<0.197)0.350 (<0.001)BEWE (1) and above0.437 (<0.001)0.646* (<0.001)0.114 (<0.133)0.627* (<0.001)BEWE (2) and above0.630* (<0.001)0.820* (<0.001)0.152 (<0.045)0.891* (<0.001)BEWE (3)0.243 (0.001)0.428 (<0.001)All scores zero0.442 (<0.001) Highest Buccal BEWEHighest Occlusal BEWEHighest Lingual BEWEHighest BEWE0.575 (<0.001)0.770 (<0.001)0.091 (0.231)0.857 (<0.001)The BEWE sextant cumulative score correlates well to surface scores (1) and above and (2) and above (0.6 and 0.9 respectively). It also correlates well with the highest BEWE per subject. Conclusion: BEWE sextant score compares well to the surface score but in cases where there is localised advanced or minimal wear the accuracy is reduced.Keywords: Erosion, Methodology and Wear
