[摘要] AbstractHighlightsThis meta-analysis systematically evaluatd the efficacy of mechanical tongue cleaning on halitosis, and showed that treatment combined with mechanical tongue cleaning could reduce risks of halitosis and Winkel Tongue Coating Index.Editor’s SummaryMechanical tongue cleaning is effective in reducing volatile sulphur compounds. However, there is insufficient evidence indicate the effective of mechanical tongue cleaning on preventing halitosis. This article found that mechanical tongue cleaning could reduce Winkel Tongue Coating Index and improve improve overall oral health condition.ABSTRACTObjective: To systematically review the effects of mechanical tongue cleaning on halitosis. Methods: Searching and collecting the RCTs about treatment combine with mechanical tongue cleaning from inception to May 2017 in the databases, like CNKI, VIP, WanFang Data, PubMed, the Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library, Web of Science. Two reviewers screened the literatures according to inclusion and excluding criteria, extracted the data independenly, assessed bias risks. In case of disagreement, the discussion shall be settled by the third reviewer. Meta-analysis was conducted by RevMan 5.3. Results: A total of 4 RCTs with 185 volunteers were included. The results of Meta-analysis showed that treatment combine with mechanical tongue cleaning has an advantage over the control group in the levels of Winkel Tongue Coating Index [MD = 2.15, 95%CI(0.93,3.36), = 0.0006], Organoleptic Assessment [MD = -0.71, 95%CI(-0.95,-0.48),.
