No significant differences between conservative interventions and surgical interventions for TMJ disc displacement without reduction

摘要

The Cochrane Central Register of Controlled Trials (CENTRAL), Medline, Embase and Scopus databases were searched. In addition reference lists of relevant review articles, textbook chapters and seven relevant journals were hand searched. Study selection Randomised or quasi-randomised controlled trials in patients with clinical and/or radiological diagnosis of acute or chronic DDwoR undergoing any form of conservative or surgical intervention were considered. The primary outcomes were TMJ pain intensity and unassisted/active maximum mouth opening (MMO). Data extraction and synthesis Study selection, data abstraction and quality assessment were conducted independently by two authors. The Cochrane risk of bias tool was used for the quality assessment. Data analysis was based on Cochrane statistical guidelines. For dichotomous data, the estimates of effect of an intervention were expressed as risk ratios (RR) together with 95% confidence intervals (Cl). For continuous data, mean differences (MD) with 95% Cl were used.
