Background Self‐ligating brackets ( SLB s) are widely adopted in clinic owing to their claimed superiorities. Here, we collected and analysed all randomized controlled clinical trials ( RCT s) comparing SLB s with conventional brackets ( CB s) and thereby investigated whether SLB s can relieve discomfort or promote oral hygiene. Methods Electronic databases including MEDLINE , Cochrane Central Register of Controlled Trials, EMBASE , World Health Organization International Clinical Trials Registry Platform, Chinese BioMedical Literature Database and the China National Knowledge Infrastructure were searched to find out RCT s comparing active or passive SLB s with CB s. Two reviewers extracted the data and assessed risks of bias independently. Any disagreement between them was resolved through discussion with a third reviewer. Meta‐analysis was conducted on Review Manager 5.3. Results A total of 12 RCT s with 575 participants were included, and eight of the trials were synthesized quantitatively. Two trials were assessed as low risk of bias, whereas others as unclear risk of bias. Passive SLB s and CB s are not significantly different in plaque control. SLB s and CB s are not significantly different in discomfort reduction at any of four time points (4 h, 24 h, 3 days and 7 days). Conclusions Clinical evidences from existing RCT s suggest that SLB s do not outperform CB s in reliving discomfort or promoting oral health in clinic.
