Abstract
            Background. Gingival recession (GR) has become one of the most common concerns in oral  mucosal diseases. It causes discomfort such as root hypersensitivity, root caries, and aesthetic  problems, leading to the development of various surgical techniques to address GRs. This study  compared the non-advanced tunnel and m-VISTA techniques in treating multiple GRs.  
  Methods. A literature search related to the efficiency of non-advanced tunnel and m-VISTA  techniques was conducted in MEDLINE (PubMed), EMBASE (ScienceDirect), Cochrane Central  Register of Controlled Trials (Cochrane Library), Springer Link, and Google Scholar. Randomized  controlled trials (RCTs) reporting periodontal parameters published in the recent four years  (2019–2023) were included and assessed for the risk of bias. All in vitro, animal, pilot studies,  case reports, and case series were excluded.  
  Results. Five RCTs were included with 195 cases of GRs. Comparing the two techniques revealed  a significant increase in keratinized tissue width (KTW) from baseline to 6 months (-1.4 mm),  in clinical attachment level (CAL) (-2.65 mm), and in recession depth (-2.7 mm) for the tunnel  technique. On the other hand, a significant increase in GR width (-2.26 mm) was found in the  m-VISTA group. Finally, there were no significant differences in probing depths.  
  Conclusion. Both techniques were effective in root coverage and may be valuable for treating  multiple GRs.
