Fibrin sealant versus sutures in periodontal surgery: A systematic review

Background: The aim of this systematic review was to assess the effectiveness of fibrin sealant compared to su-tures in periodontal surgery.Methods: Five electronic databases (PubMed, Scopus, EBSCO, Cochrane and Web of Science) were screened from initiation to January 2021 for randomized controlled trials (RCTs) comparing fibrin sealant to sutures in peri-odontal surgery using this search equation: (Periodont* OR Periodontitis) AND (fibrin tissue adhesive OR fibrin glue OR fibrin sealant OR fibrin sealant system OR fibrin adhesive system OR fibrin fibronectin sealant system). Quality assessment of the included studies was performed using the revised tool to assess risk of bias in randomized trials (RoB 2). The level of evidence was evaluated using the GRADE tool.Results: A total of 240 publications were found as search results in the screened databases. Four RCTs were included in this systematic review based on predetermined inclusion criteria. The trials were published between 1987 and 2014. All the RCTs compared fibrin sealant to sutures in periodontal surgery. The sample size included 101 patients. The overall risk of bias in this systematic review was at high risk in 75% of the studies, while 25% of the studies raised some concerns. The level of evidence evaluated using GRADE tool was very low.Discussion: The current systematic review indicates a low level of evidence of the use of fibrin sealant as an alternative to sutures in periodontal practice. More interventional and multicentric studies should be conducted to support and confirm the results of the included studies.

Automated summary

This systematic review found low-level evidence for the use of fibrin sealant as an alternative to sutures in periodontal surgery, indicating a need for more research to support and confirm the results of the included studies.
