STUDY SELECTION: Randomised controlled trials or quasi-randomised controlled trials that included a minimum follow-up period of 12 months.Data extraction and synthesisTwo review authors independently and in duplicate assessed the eligibility of all reports identified in the searches. Authors were contacted for additional information where required. RESULTS: No randomised or quasi-randomised controlled trials were found. CONCLUSIONS: We found no randomised or quasi-randomised trials of interventions to treat displaced luxated permanent front teeth. Current clinical guidelines are based on available information from case series studies and expert opinions. Randomised controlled trials in this area of dental trauma are required to robustly identify the benefits of different treatment strategies.
