Data sourcesCochrane Oral Health Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), Medline, Embase, ISI Web of Science, ISI Web of Science Conference Proceedings, BIOSIS, OpenSIGLE. Reference lists of all eligible trials and review articles, and their reference lists were searched.Study selectionTrials were selected if they met the following criteria: randomised or quasi-randomised controlled trial, involving replacement and repair of amalgam restorations.Data extraction and synthesisTitles and abstracts were assessed independently by two authors. Full papers were obtained for relevant articles. Data synthesis was to follow Cochrane Collaboration statistical guidelines.Results145 potentially eligible studies were identified. Only three studies were analysed further but none of these met the inclusion criteria and all were excluded from this review.ConclusionsThere are no published randomised controlled clinical trials (RCTs) relevant to this review question. There is a need for methodologically sound RCTs reported according to the Consolidated Standards of Reporting Trials (CONSORT) statement (www.consort-statement.org/). Further research needs to explore qualitatively the views of patients on repairing versus replacement and investigate themes around pain, distress and anxiety, time and costs.
