Abstract:

BACKGROUND: Loosen teeth are a long-term problem for dentists in treatment of periodontal disease, the use of periodontal splints is still in dispute.　
OBJECTIVE: To assess the effectiveness and safety of periodontal splints for the treatment of periodontal mobile teeth.
METHODS: A computer research of Cochrane Library (Issue 4, 2009), MEDLINE (1966/November 2009), EMbase (1980/November 2009), China Biomedicine Database (1978/2009), CNKI (1989/2009), and VIP (1989/2009) was performed to search randomized controlled trials for periodontal splints in treatment of periodontal repair. Quality assessment and data extraction were performed by two reviewers independently. Statistical analysis of the study data was performed with RevMan 5.0 software offered by Cochrane Cooperative net.
RESULTS AND CONCLUSION: Nine studies of randomized controlled trials were included. The included studies did not report the splint-related serious adverse reactions. Existing researches show that periodontal splint can improve the mobility of loosed teeth with periodontal diseases and periodontal status, permanent splints are more effective than temporary splints, fixed permanent splints are more effective than removable permanent splints, super-strong fiber splints are more effective than traditional stainless steel wire combined resin splints, precious metal splints are more effective than cheap metal splints. Due to few high-quality randomized controlled trials and limited cases of patients, there is a high possibility of selection bias and publication bias.
