Effectiveness of surgical root coverage on dentin hypersensitivity: A systematic review and meta-analysis

To assess the effect of surgical root coverage (RC) on dentin hypersensitivity (DH) associated with gingival recession.Two independent reviewers conducted electronic literature searches in MEDLINE (PubMed), EMBASE, Cochrane Library, Web Of Science, DentistryOral Sciences Source, ScienceDirect, and ClinicalTrials.gov databases as well as a manual search to identify eligible clinical studies from January 2000 to March 2022. Randomized controlled trials (RCTs) comparing two surgical RC techniques or a surgical RC technique with or without adjuvant were included. Meta-analyses were performed on data provided by RCTs.Thirteen RCTs with a total of 701 patients (1086 recessions) were included. The percentage of DH suppression was 70.8% (95% confidence interval [CI] [64.4-76.6]; ISuccess of surgical RC is associated with DH suppression.
