1.An experimental study on the effect of topical application of stannous fluoride to the stripped enamel surface.
Korean Journal of Orthodontics 1971;2(1):23-28
In this study, sections of twenty eight teeth were used to investigate the effect of topical application of 8% stannous fluoride on the decalcification rate of enamel surfaces stripped in a manner suggested for orthodontic purpose. The enamel treated with a single application of a fluoride had a significantly lower tile rate of decalcification for the first 96 hours to lactate buffer solution. After double application of fluoride, decalcification rate decreased signicantly. This study suggested that the continuing protection of stripped surfaces should be sought by regularly scheduled treatment of the enamel with the topical application of fluoride and regular use of a fluoride containing dentifrice.

OBJECTIVEThis study aims to assess the effects of desensitizing toothpaste containing stannous fluoride on dentine hypersensitivity by performing Meta-analysis of randomized controlled trials (RCT) involving the treatment of dentine hypersensitivity with stannous fluoride-containing toothpaste.
METHODSThe study was developed based on the Cochrane handbook for systematic reviews of interventions (Version 5.1.0) and included the following: search strategy, selection criteria, data extraction, and risk of bias assessment. We searched electronic databases such as CNKI, CBM, PubMed, Embase, and Cochrane Library up to January 2015. RCT of treating dentine hypersensitivity with stannous fluoride-containing toothpaste were included. Data extraction and domain-based risk of bias assessment were independently performed by two reviewers. Meta-analysis was performed with RevMan 5.3 software.
RESULTSSix RCT with 494 patients (247 in the experimental group and 247 in the control group) were included. The results of Meta-analysis showed that the desensitizing effect of stannous fluoride-containing toothpaste was significantly better than that of control in tactile sensitivity test (SMD=1.41, 95% confidence interval 0.74-2.09, P<0.00001) and air blast test (SMD = -1.16, 95% confidence interval -1.84--0.48, P<0.000 01).
CONCLUSIONCurrent evidence shows that stannous fluoride-containing toothpaste is effective in treating dentine hypersensitivity in clinic. However, due to limited sample size and lower quality of the included studies, more high quality and large-sample RCT are needed to further verify the evidence.
