Overlap with other reviews

Reviews that include the same primary studies are not independent evidence. Shared counts match studies by PMID, DOI or NCT, and otherwise by author and year (a probable match). Only the non-Cochrane dental reviews have study lists, so overlap with Cochrane reviews is not counted yet.

Review question

ElementPlanned (methods)Found (results)
PopulationLarge-animal models (canine, porcine, primate) or human subjects with recession defects, no age or gender restriction; small-animal models excluded41 preclinical studies (32 canine, 5 porcine, 4 primate models) with artificial recession-type defects; 43 clinical studies (27 block biopsy, 16 soft-tissue biopsy; mostly case reports/series)
InterventionRoot coverage procedures (RCPs) using any surgical technique (flaps, grafts, soft-tissue substitutes) with or without adjunctive biologicals or membranesCAF with or without CTG or soft-tissue substitutes most frequent; adjunctive EMD, other biologicals and membranes; LSF, FGG, tunneling
ComparisonDifferent RCPs; RCPs with versus without adjunctive biologicals or membranesMeta-analysed in canine models of chronic defects: RCP with versus without biologicals (n=10), with versus without EMD (n=5), with versus without membrane (n=5); pooled means for CAF, CAF + CTG, CAF + SUB
OutcomesQualitative or quantitative histological evaluation of autopsy (animals) or biopsy (humans) specimens: new epithelium, connective tissue, cementum, bone, periodontal ligament, soft-tissue thickness; periodontal regenerationPooled means and Hedges g for epithelium, CT attachment/adhesion, cementum, bone and soft-tissue thickness; descriptive histology for human biopsies
Study designsPreclinical and clinical studies of any design; in vitro studies and reviews excludedPreclinical studies (ex vivo autopsy) and clinical studies, mostly case reports and case series (one RCT)
TimingNot specified (observation time subgroups early <=6 weeks and delayed >=10 weeks defined for meta-analysis)Early (<=6 weeks) and delayed (>=10 weeks) healing in canine/minipig models; human healing times up to 3 years
