To the best of our knowledge, the equality of CAF + EMD and CAF + FCTG regarding complete root coverage in Miller class I and II recession-type defects is still uncertain.?Aim: The aim of the current paper is to compare the effect of CAF + EMD versus CAF + FCTG regarding complete root recession coverage. Thereby, equality on the longer term of both therapeutic options is hypothesized (H0- hypothesis).Materials and methods: Three reviewers searched independently within the electronic database Pubmed/Medline. Only RCTs reporting quantitative data for the outcome variable percentage complete root coverage (%CRC) for the therapeutic options CAF + EMD or CAF + FCTG were considered. Additionally a manual search in the reference lists of all included publications was accomplished.Results: After electronical and manual search for relevant studies, the three independent reviewers (DZ, TU, AL) screened 552 titles, resulting in 102 abstracts and 41 full-texts. Eventually, twenty-five papers could be included for meta-analysis. By comprehensively comparing data from RCTs for the outcome variable ?percentage complete roo
