Delphi Study on the non-Restorative Management for Erosive Tooth Wear

Objectives: Given the rising prevalence of Erosive tooth wear (ETW), it is important to establish the baseline knowledge and understanding of the condition by Dental Healthcare Personnel (DHCPs). The aim of this study was to assess the scientific opinion of DHCPs on non-restorative management of ETW.
Methods: Using an independently guided, modified-Delphi methodology, five domains of focus were identified (Improving awareness of ETW; Recognising and addressing risk factors for ETW; Consequences of untreated ETW; Current management options and optimal future approaches for ETW; Further research required to better understand management of ETW). These domains were discussed and edited by a panel of 5 experts. 43 statements were constructed and used in an online survey for testing amongst DHCPs in EU/USA via a market research (convenient sampling/database) basis, with a minimum of 150 (USA) and 150 (EU) responses. Each statement was presented along with a four-point Likert scale (strongly or tend to disagree/tend to or strongly agree). Consensus threshold was established at 75% agreement. Demographic data on respondent country, role/time in role were captured.
Results: 300 responses from DHCPs across EU and the USA were analysed. 28/43 statements attained very strong agreement (≥90%), 10/43 attained strong agreement (<90% and 75%), while 5/43 did not meet the established threshold for consensus (≥75%).
Conclusions: 4 key recommendations were developed:; (i) Awareness of the impact of ETW should be improved by policymakers to reduce the impact of the condition and improve quality of life for patients; (ii) A simple ETW risk assessment form should be developed and implemented in dental practice globally, and digital measurement tools should be used within practice to measure progression of ETW; (iii) DHCPs should caution patients at risk of ETW about erosive foods and drinks and (iv) There is a need for further research into the benefits of different fluoride ions combined with other agents for prevention of ETW.
