AimThe aim of this systematic review was to investigate the quality of evidence for methods used to diagnose, restore and prevent dental erosions, by evaluating and summarising clinical controlled studies and in situ studies covering this field.Material and MethodsThree databases, PubMed, Embase and Cochrane database, were searched for studies published until October 2023. Studies fulfilling the selection criteria were selected, and the risk of bias of the included studies was assessed. Two authors independently reviewed the studies, evaluated their risk of bias and extracted data from the included studies. The certainty of evidence of the findings in the studies was determined using GRADE.ResultsThe literature search identified 7176 records. Out of these, 19 studies were included in this review, three revolving diagnostics, three revolving treatment and 13 revolving prevention. However, due to the fact that only few studies with a small number of participants have investigated the same methods on the same outcome, the studies do not constitute any body of evidence.ConclusionThis systematic review highlights the shortage of data on methods used for diagnostics, restorative treatment and prevention of dental erosions. More knowledge is needed to strengthen the scientific evidence regarding methods used for dental erosions.
