Abstract: PURPOSE: To appraise the quality of Chinese clinical trials during recent 10 years about the treatment of permanent anterior dental trauma with evidence-based quality control methods. METHODS: The CNKI (Chinese National Knowledge Infrastructure) and Wanfang electronic database with key words "permanent anterior dental trauma " were searched. Two hundred and forty-five papers were obtained during recent 10 years, 46 key papers about the treatment of permanent anterior dental trauma were retrieved. The quality of the Chinese clinical trials according to the consolidated standards of reporting trials (CONSORT) and strengthening the reporting of observational studies in epidemiology (STROBE) statement were assessed. RESULTS: Within the 46 key papers, there were 8 randomized controlled clinical trials, while the other 38 papers were observational studies. It was hard to evaluate precisely due to the lack of scientific information. The randomized controlled trials lacked details for randomization, allocation concealment and blinding compromised the quality. CONCLUSIONS: For the clinical studies about the effects of stabilization of permanent anterior dental trauma, the study quality needs to be improved, and progress should be made both in the clinical study design and the paper writing.
