Background:
Gingival recession is a concern in aesthetic and functional perspective. The tunneling technique (TT) is one of the effective root coverage treatments in some gingival recession defects and is associated with favorable outcomes. This paper aims to evaluate the effectiveness of platelet-rich fibrin (PRF) and connective tissue graft (CTG) in gingival recession treatment with TT.
Methods:
This systematic review used the PRISMA method and electronic bibliographic searches were conducted on seven databases (Google Scholar, Wiley, Pubmed, Sage, Ovid Technologies, Quintessence Publishing, Springer) from December 2018 to January 2023. The search focused on randomized clinical trials (RCTs) that reported TT outcomes in the treatment of Miller class I and II recession with a minimum of six months follow-up.
Results:
Three out of 399 studies met the inclusion criteria. The three selected studies presented PRF and CTG use in multiple gingival recessions to evaluate tissue condition and clinical parameters before and after the surgical procedure. The clinical parameters evaluated were probing pocket depth (PPD), recession width (RW), width of keratinized gingiva (WKG), and vertical depth of recession (VDR). TT with PRF and TT with CTG is effective in treating gingival recession. PRF is well accepted by patients with a less invasive procedure compared to the CTG procedure. However, TT with CTG showed better results in all parameters at follow-up.
Conclusions:
TT with PRF can be used as an alternative to treat some gingival recession defects. However, TT with CTG produced better clinical results in recession closure.
