Plain English summary of protocol
Background and study aims
Tooth wear is a non-reversible loss of dental tissue and the prevalence has increased. Early diagnosis and prevention are important, however, clinical assessment of tooth wear sustains challenges. These challenges involve relying on a qualitative assessment of tooth wear, including heavily relying on visual assessment and difficulty in comparing tooth wear in a patient over time. Being able to assess tooth wear on scans directly, rather than only in the patient's mouth, may assist the dentist in making a reliable assessment of tooth wear. On a 3D scan, the dentist can have a better view of the teeth, zoom in, save measurements for later on, and show the patient the problem.
Who can participate?
Any adult with tooth wear ranging from none to severe on any tooth can participate.
What does the study involve?
The participant will get a 3D scan of their teeth and the clinician will perform the standard clinical examination for tooth wear (Basic Erosive Wear Examination).
What are the possible benefits and risks of participating?
The possible benefit of participating is that participants may discover conditions of their teeth they were otherwise unaware of – this can be related to the trial’s subject (tooth wear) or unrelated (for example, caries that need treatment). The risks of participating are that some participants may feel minimal discomfort from having their teeth scanned.

| Scientific title | Investigating the utility of 3D intraoral scan imaging to score tooth wear compared to visual clinical assessment |
| Study objectives | To assess the diagnostic accuracy of intraoral 3D scanner-derived detection by dichotomous outcome (yes/no) of tooth wear compared to the standard clinical visually-derived direct scoring of tooth wear. |
| Ethics approval(s) |
Approved 08/04/2024, Leicester South REC (2 Redman Place, Stratford, London, E20 1JQ, United Kingdom; +44 207 104 8079; leicestersouth.rec@hra.nhs.uk), ref: 24/EM/0064 |
| Health condition(s) or problem(s) studied | Tooth wear in a variety of severity from none to severe |
| Intervention | The patient will be screened according to the inclusion and exclusion criteria - they may have varying degrees of tooth wear. The clinician will then perform the 3D intraoral scan (using CE-marked equipment within its intended purpose), and the clinician will then perform the standard clinical examination for tooth wear (the Basic Erosive Wear Examination). This is a visual examination. Without involving the patient, the clinician will also perform the tooth wear examination directly on the scan. Two weeks later, the clinician will score the tooth wear directly on the scan once more. Another clinician, blinded to the clinical truth, will also perform the tooth wear assessment on the scan. |

| Phase | Not Applicable |
| Drug / device / biological / vaccine name(s) | Trios 5 intraoral scanner |
| Primary outcome measure | Tooth wear measured using intraoral 3D scanner and standard clinical visually-derived direct scoring at baseline and 2 weeks |
| Secondary outcome measures | 1. To assess diagnostic accuracy of an algorithm on tooth wear detection on patient-level by dichotomous outcome (tooth wear: yes/no) compared to the clinical reference standard scoring of tooth wear (BEWE sum score cut-off 0-2 vs. 3-18) 2. To assess diagnostic accuracy of an algorithm on tooth wear detection on tooth-level by dichotomous outcome (tooth wear: yes/no) compared to the clinical reference standard scoring of tooth wear (BEWE score 0-1 vs. 2-3) 3. To assess diagnostic accuracy of an algorithm on dentin exposure detection on tooth-level by dichotomous outcome (dentin exposure: yes/no) compared to the clinical reference standard scoring of dentine exposure (dentine exposure: yes/no) 4. To determine the inter- (reproducibility) and intra-examiner (repeatability) of the reference standard on-scan assessment by 2 different examiners 5. To determine the reproducibility of an algorithm’s detection of tooth wear on-scan compared to on-scan assessment performed by examiners 6. To determine the repeatability of an algorithm’s detection of tooth wear |
