Resumen

Objective: To compare the ef fectiveness of the conventional technique and cordless technique in gingival displacement. Materials and Methods: A bibliographic search was carried out until August 2023, in the biomedical data-bases: Pubmed/Medline, Cochrane Library, Scielo, Scopus and Google Scholar. Included studies reporting the gingival displacement of vital teeth using the cordless and conventional techniques comprised clinical trials, articles in English and without time limits. The RoB 2.0 tool was used to assess the risk of the included studies and the GRADEPro GDT tool to assess the quality of the evidence and the strength of recommendation of the results. Results: The preliminary search yielded a total of 489 articles, discarding those that did not meet the selection criteria, leaving only 15 articles. A total of fourteen articles entered a meta-analysis. It was found that the conventional technique caused better gingival (width) displacement than the cordless techniques, however, it caused more bleeding. Furthermore, among the wireless techniques, the one using polyvinylsiloxane obtained better results. Conclusions: The literature reviewed suggests that the conventional technique resulted in a better gingival displacement (width) than the cordless techniques, however, it causes a greater periodontal injury.
