Tooth Surface Loss
Also written as: TSL — Tooth Surface Loss
An umbrella term covering the progressive, irreversible loss of dental hard tissue from causes other than dental caries or trauma, including erosion, abrasion, and attrition.
Full Definition
Tooth surface loss (TSL) is a collective clinical term encompassing three distinct non-carious processes: erosion (chemical dissolution of enamel/dentine by intrinsic or extrinsic acids), abrasion (mechanical wear from extrinsic agents such as toothbrushing), and attrition (tooth-to-tooth wear). Editors must understand that TSL is the umbrella term and that the three subtypes are not interchangeable with it or with one another. The BEWE (Basic Erosive Wear Examination) index is a standardised scoring tool for TSL assessment, and its abbreviation must be expanded on first use. TSL is particularly significant in paediatric, dietary counselling, and restorative dental writing, where aetiology determines management.
Usage
Usage note: Always clarify whether TSL is multifactorial or aetiology-specific; do not use 'erosion' as a blanket synonym for TSL in clinical documents.
In Context
- "Moderate tooth surface loss affecting the palatal surfaces of the upper incisors was consistent with a history of gastric reflux." — Clinical assessment record
- "The manuscript used 'erosion' throughout where the broader term 'tooth surface loss' was clinically appropriate, as multiple aetiologies were present." — Peer review comment
