AIM To assess the effect of surgical root coverage on dentin hypersensitivity (DH) associated with gingival recession. MATERIALS AND METHODS Two independent reviewers conducted electronic literature searches in MEDLINE (PubMed), EMBASE, Cochrane Library, WOS, DOSS, 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 root coverage techniques or a surgical root coverage technique with or without adjuvant were included. Meta-analyses were performed on data provided by RCTs. RESULTS Thirteen RCTs with a total of 701 patients (1086 recessions) were included. The percentage of DH suppression was 70.8% (95% CI [64.4-76.6]; I2 = 39.2% [3.5-61.8], Q-test = 0.02) after surgical root coverage. Recession reduction and percentage of root coverage were both statistically significantly associated with DH suppression (estimate = 0.66 [0.10-1.23], p-value = 0.022, R2 = 14.45% and estimate = 0.04 [0.01-0.08], p-value = 0.012, R2 = 29.54%, respectively). CAF + CTG showed results statistically more effective than CAF + XCM in DH suppression (73.3% [65.6-79.8] and 61.4% [51.7-70.3], respectively; p = 0.048). CONCLUSION Success of surgical root coverage is associated with DH suppression. This article is protected by copyright. All rights reserved.
