TWES
Also written as: TWES — Tooth Wear Evaluation System
Abbreviation for Tooth Wear Evaluation System, a comprehensive scoring system used to classify and stage tooth wear combining aetiological and severity assessments.
Full Definition
The Tooth Wear Evaluation System (TWES) is a structured clinical and radiographic scoring system developed to standardise the documentation and grading of tooth wear in research and clinical practice. It integrates aetiological classification (erosion, abrasion, attrition, or combination) with a severity scale, enabling both cross-sectional prevalence studies and longitudinal monitoring. In research manuscripts, editors should confirm that the TWES version is specified (TWES 2.0 is the current version), that the aetiological sub-scores are reported separately from the severity scores, and that the system is not conflated with BEWE, which scores erosive wear only. The TWES provides a broader remit than BEWE by encompassing all wear aetiologies.
Usage
Usage note: Do not substitute TWES for BEWE; BEWE scores only erosive surfaces, whereas TWES encompasses all wear aetiologies. Specify the version number when citing TWES.
In Context
- "Tooth wear severity was graded using the TWES 2.0, which allows separate recording of erosive and non-erosive wear components." — Epidemiological tooth wear survey methods
- "The use of TWES rather than BEWE was justified by the multi-aetiological nature of wear observed in the study cohort." — Discussion section of a tooth wear prevalence study
